Introduction: Many of today’s greatest inventions have been created by “accident” , meaning that these products were created in the midst of a scientist trying to make something else. Three of these products, two of which were staples during many of our childhoods, are things we could not imagine a time without them. The “accidents” we will be focusing on are nylon (yes, the material panty hose are made of), Silly Putty®, and the bouncy ball.
Nylon
Nylon, a synthetic polymer fiber, was invented by Wallace Hume Carothers at the E.I. DuPont de Nemours Company in Delaware in 1934. Nylon stockings became a huge hit as soon as they were released during World War II after a public supply cut-off.
Although Carothers receives recognition for the creation of the polymer, another DuPont employee may the actual inventor. Julian Hill worked with Carothers, and had spent time developing a process where a long fiber with a silky texture could be created of carbon polymers. Carothers may have had a psychological issue, and committed suicide in 1937. The company accredited the invention of nylon to him in honor of him. Nylon was created entirely from petrochemicals unlike previous artificial fabrics like rayon and acetate, which were plant based. Nylon was designed as a synthetic silk for women’s stockings. The material was intended to be less expensive while adding qualities such as strength and insulation. Nylon is not only used in stockings, but is also used in an enormous amount of other products, including basketball nets, carpeting, clothing, fishing line, guitar strings, surgical sutures, tennis racquet strings and vehicle upholstery, among others. Nylon has even been to the moon. On the first trip to the moon, the astronauts wore space suits containing nylon fibers. The flag that Neil Armstrong planted there was also made of nylon.
Silly Putty One of the most important resources needed for World War II war production was rubber. It was essential for tires and boots, which kept the soldiers moving. It was also important for gas masks, life rafts, and even bombers. Early in the war, Japan attacked many of the rubber producing countries in Asia which drastically affected the supply route. Due to this rubber was being conserved back in the US. Civilians were also asked to donate old rubber products, and there were numerous propaganda posters instructing people on the importance of carpooling to save tires, and taking care of the rubber products at home so they would last the duration of the war. Silly Putty was truly created by accident. In 1943, engineer James Wright was attempting to create a synthetic rubber that had similar properties, but that could be made with non-restricted ingredients when he found something unusual. In a test tube, he had combined boric acid and silicone oil, producing an interesting gob of goo. Silly Putty. Wright performed several tests on the substance and found that it could bounce when dropped, stretch farther than regular rubber, didn’t collect mold, and had a very high melting point. Although it was interesting, it didn’t contain the properties of rubber that were needed. Wright, nor other scientists could find a practical use for the substance. Even though the substance was not practical, it continued to be entertaining. The “nutty putty” was passed around to family and friends. It was even taken to parties to be dropped, stretched, and molded to the delight of many. In 1949, Ruth Fallgatter, a toy store owner, took the putty and put it in her toy catalog. It was a great seller, but was dropped from the catalog the next year.
Peter Hodgson, Fallgatter’s advertising agent, saw opportunity in the putty. He bought a large quantity of it and had Yale students separate it into one ounce balls and place them in red plastic eggs. After many name suggestions, he settled on the same “Silly Putty.”
FUN FACT: Silly Putty was originally a toy for adults, but became popular with children by 1955.
Bouncy Ball Yet another polymer was discovered by accident. In 1965, Norman Stingley, a chemical engineer at Bettis Rubber Company, decided to do some off the record experiments with the chemicals at Bettis. One day, he created this “gooey, rubberlike” material and compact the material with around 3,500 pounds of pressure. Turns out, the substance was able to withstand and keep its shape even under this amount of pressure, though if the material was struck too hard, it crumbles. This material, through observation by Stingley, could bounce to tremendous heights. Stingley had made a synthetic rubber! Stingley, through loyalty, offered the invention to his own company, but they denied it, saying it was too risky and why would anyone want to play with something that could possibly fall apart. Thankfully, another company wanted Stingley’s accidental polymer, and Stingley’s gooey substance became the “Wham-O Superball”. Several more tests were completed on the material to make it stronger, and eventually Stingley tweaked the formula enough to apply for a patent for his material called “Zectron” in August 1965. Some fun facts about the Superball is that there is no other ball in history that exhibits the same bouncing quality and pressure resistance as the Superball. Also, the term “Super Bowl” came from the super ball. The owner of the AFL’s Kansas City Chiefs was thinking about how to make the title of the contest between the NFL and AFL catchier. Then, Lamar Hunt, owner of the AFL’s Kansas City Chiefs, thought about how he saw his daughter playing with a “high-bouncing” Super Ball a few days prior. A little word placement, and eventually the word “ball” changed to “bowl” and the rest is history.

...two-stage emulsion polymerization method, a series of poly(methyl methacrylate-acrylonitrile)/poly(ethyl acrylate-n-butyl acrylate) [P(MMA-AN)/P(EAnBA)] latex interpenetrating polymer networks (LIPNs) were synthesized by varying AN content, ratio of network I/network II, crosslinker content, and introducing chain transfer agent. The damping properties of the LIPNs were investigated using a Rheovibron Viscoelastometer. The results indicates that a suitable content of AN can improve the damping properties of the LIPNs. Three kinds of fillers were incorporated into the LPINs, respectively, to measure the change in the damping properties. Mica and TiO2 both increased the damping properties of the LIPNs over the wide temperature range. For TiO2-filled LIPNs, it was observed that the tan values exceeded 0.4 over 112.6°C temperature range from 50 to 72.6°C. © 2000 John Wiley & Sons, Inc.

Forming of Polymer Nanofi Bers by a Pressurised Gyration Process

...Macromolecular Rapid Communications Communication Forming of Polymer Nanofibers by a Pressurised Gyration Process Suntharavathanan Mahalingam, Mohan Edirisinghe* A new route consisting of simultaneous centrifugal spinning and solution blowing to form polymer nanofibers is reported. The fiber diameter (60–1000 nm) is shown to be a function of polymer concentration, rotational speed, and working pressure of the processing system. The fiber length is dependent on the rotational speed. The process can deliver 6 kg of fiber per hour and therefore offers mass production capabilities compared with other established polymer nanofiber generation methods such as electrospinning, centrifugal spinning, and blowing. 60 Frequency (%) 50 40 30 20 10 0 0 50 100 150 200 250 300 350 400 Fibre diameter (nm) 1.

Transparent!

...How to make a crab shell see-through 30 November 2011 Researchers in Japan have made a crab shell transparent. Then, using knowledge gained from this activity, they created a transparent nanocomposite sheet, incorporating powdered chitin from crab shells. The nanocomposite could have applications in devices that need a high light transmittance, such as flat panel displays. Scientists have previously used cellulose from plants and chitin to strengthen materials, giving biologically-inspired nanocomposites. If natural nanofibres are dispersed widely enough in a transparent polymer matrix, they can strengthen the polymer and the resulting nanocomposite material will retain its transparency. Work on optically transparent polymers containing cellulose nanofibres shows they have a low axial thermal expansion coefficient, meaning their size does not vary with temperature, making them ideal for use in flexible flat panel displays and solar cells. Muhammad Iftekhar Shams and co-workers from Kyoto University took a whole crab and treated it with hydrochloric acid, sodium hydroxide and ethanol to remove the minerals, proteins, fats and pigments, respectively. This gave a chitin-only crab shell, which they immersed in an acrylic resin monomer. Following polymerisation, they obtained an entirely transparent crab shell. The shell retained its shape and detail, right down to the creature's eyes.  Preparing the transparent crab shell: (a) original shell, (b) shell after removal of matrix...

Research Paper

...Example Research Paper on Polymer Chemistry: Introduction Polymerization refers to a chemical reaction that results in bonding of two monomers to form a polymer (Tarle, 435). A polymer molecule is made up of hundreds, thousands, or even millions of atoms joined together to form a chain with an extended length at least an order of magnitude greater than its thickness (Peacock & Calhoun, 2006). Polymers have variations of molecular weight (length), branching, steric configuration, interconnections and chemical defects (Tarle, 435). A polymer is made up of many elements. One can consider a polymer as a thread with every link of this string forming a fundamental unit which is in turn made of hydrogen, carbon, silicon and oxygen(Tarle, 435). They are mostly made up of hydrocarbons though other elements such as Sulphur, nitrogen and chlorine may also be found(Carraher & Charles, 2). The molecules are held together by covalent bonds that are branched, linear, or networked to form the polymeric material (Carraher & Charles, 2). While most polymers have carbon as their backbone, others have silicon as the main element holding the polymer (Carraher & Charles, 2). . The history of polymerization The science of polymerisation began way back in the 19th century where alumina-silica glass and phosphoric acid was widely applied to fill dentures (Carraher & Charles, 2). . However, the compounds had very poor mechanical properties and high solubility. This meant that they...

...Chapter 2 Strain energy functions The aims of constitutive theories are to develop mathematical models for representing the real behavior of matter, to determine the material response and in general, to distinguish one material from another. As described in the preceding chapter, constitutive equations for hyperelastic materials postulate the existence of a strain energy function W . There are several theoretical frameworks for the analysis and derivation of constitutive equations, for example the Rivlin-Signorini method where the governing idea is to expand the strain energy function in a power series of the invariants, or the Valanis-Landel approach expressing the strain energy directly in terms of the principal stretches [115]. In this chapter, we make no attempt at presenting these methods but instead, we present some classical explicit forms of strain-energy functions used in the literature for some isotropic hyperelastic materials. Many other models have been proposed (for example, a collection of constitutive models for rubber can be found in [32]). 2.1 2.1.1 Strain energy functions for incompressible materials Neo-Hookean model The neo-Hookean model is one of the simplest strain energy functions. It involves a single parameter and provides a mathematically simple and reliable constitutive model for the non-linear deformation behavior of isotropic rubber-like materials. Its strain energy function is W= µ (I1 − 3), 2 (2.1) where µ >...

Polymers are made up of repeating monomer units with a high molecular weight. Their chemical reactivity depends on the chemistry of their monomer units, but their properties depend mainly on how the monomers are assembled together. Nearly all polymers exist with a range of molecular weight and for convenience the reported molecular weight of a polymer is the average molecular weight.

Chemistry Ert Water Piping Comparison

...COMPARISON OF WATER PIPING PVC and PEX Extended Research Task Introduction Polymers are nearly everywhere we look in present-day society. We use them for many different purposes as certain polymers can have certain characteristics which determine its applications. These characteristics depend on the very small intra and inter molecular bonding as well as their individual functional groups that greatly contribute to their properties. PVC and PEX are two very common polymers used to transport cold water in residential buildings; however their chemical and microscopic structures differ, giving each polymer its own unique properties. The purpose of this investigation is to compare the properties of each polymer determined by their inter and intra molecular structures. Properties needed in pipes for cold water transportation include flexible, lightweight, cost effective and safe for household/buildings. Polyvinyl Chloride Polyvinyl chloride (PVC) has many uses; one of its uses is water piping in residential buildings, due to its low cost, light weight , good insulation and low maintenance (“Polyvinyl chloride,” 2015) it suits the application perfectly. PVC is made from the polymerisation of the monomer vinyl chloride (VCM) displayed in Image 1, and achieves these properties due to its molecular structure.

Alloying: Copper and its alloys are widely used in deep draw and flat stamped products because they have excellent electrical and thermal performance, good resistance to corrosion, high ductility and relatively low cost. Thermoplastic polymeric materials Polymer processing temperature: The effect of temperature change on polymers * When substances made of small molecules are heated, they simply melt and form a free-flowing liquid; however with polymers the process is more complex. * When polymers are cooled, they will often become very brittle. When heated, the polymers will first become flexible before melting. * This is due to their structure. In some polymers, there are areas of crystalline and amorphous regions. In the “glassy” state, the tangled polymer chains in the amorphous region become “frozen”, which prevents easy movement of the chains relative to each other. If the polymer is forced to change shape, it does so by breaking.
