...Abstract Conductive polymers or, intrinsically conducting polymers (ICPs) are organic polymers that can have metallic conductivity or semiconductivity via conjugation and co-doping. Polypyrrole (PPy) as a kind of heterocyclic conjugated conductive polymers is considered to be the most prospective electric conductive polymer due to its relatively high conductivity, stability, and other characteristics. Recently, PPy /magnetic nanoparticles composite materials have become a research hotspot, for its potential application in electromagnetic shielding, molecular electronics, nonlinear optics, absorbing materials, etc. The preparation of this material is mainly through in-situ polymerization. The polymer wrapped around nanoscale magnetic particle via particle-substrate interaction to form a core-shell structure of polymer /magnetic nanoparticles composite materials. But study also shows that this kind of polymer coat may reduce the saturation magnetization of the magnetic nanoparticles. Three methods—chemical method, electrochemical and O/W microemulsion synthesis method were used to synthesize different structural types of PPy. The Four probe method shows that it has good conductivity (793.7 S.m-1).The TEM indicates that the PPy synthesized through O/W microemulsion has better controlled nano size and thus we chose the PPy synthesized by O/W microemulsion to interact with magnetic Co nanoparticles via ligand substitution reaction. The PPy/ magnetic nanoparticles composite material...

...Introduction: Polymer is a kind of long, large molecules which have a repeating pattern according to the monomers they are made of. Each pattern These sub-units are typically connected by covalent chemical bonds and each polymer consists roughly of between a thousand and a million monomers. The polymers were commonly found in the nature (e.g. animals, plants). Meanwhile, the polymers were produced synthetical a lot to create different kinds of plastics. Vinyl, neoprene, polystyrene, nylon are very common synthetic polymers and Polyaniline (PANI) is also a conducting polymer. Polyaniline is among a family of conductive polymers, and has properties similar to some metals. It was discovered as “aniline black” in an organic form as part of melanin, a type of organic polymer in 1934. Melanin does many things in nature, including protecting the skin by regulating UV exposure through a polyaniline interaction. In a natural form, polyaniline is usually found folded with other polymers. In the late 1990s it became evident that polyaniline was a flexible and highly useful polymer, and could be used in applications ranging from intelligent windows to computer chips. Polyaniline is a unique type of polymer because it is a type of semiconductor. Polyaniline can be configured to conduct across a wide range, from being utterly non-conductive for insulation use to highly conductive for other electrical purposes. Polyaniline, like other polymers, is highly flexible, which makes it appealing...

...Plastics in the Oceans We live in an increasing disposable world. Everything from food to electronics ends up in a landfill somewhere. We are always looking for newer and better products to replace what we already have. The consequences of this behavior are resulting in more and larger landfills, toxic water and a myriad of other problems. With our growing population and excessive consumption, the items we use everyday are becoming disposable so the garbage problem continues to expand exponentially. It is a readily accepted fact that plastics has made our lives both easier and safer, but, at the same time, has also left a damaging imprint on our environment and even our health. The waste management industry has done a very clever job of keeping the inner workings of landfill disposal cloaked in secrecy. As a result we give less and less thought to what actually happens to all the trash we throw away every day. Our culture of convenience is so dominant we do not even see the consequences of our actions. Journalist and filmmaker Heather Rogers, in her essay “The Hidden Life of Garbage” takes us on a journey of garbage disposal that most of us never think about once we take the trash to the curb. She explains one particular method that should give us all pause for thought: In new state-of-the-art landfills, the cells that contain the trash are built on top of what is called a “liner.” The liner is a giant underground bladder intended to prevent contamination of groundwater...

...Marie O'Campo Environmental Science Lab Lab Report 2 Sustainability We hear the words 'sustainable' and 'sustainability' almost every day. But what does it mean exactly? Is it about people and culture, our environment, or jobs and money? Is it about cities or the country? Is it about you and me or is it something for other people to worry about? Sustainability is about all of these things and more. Sustainability could be defined as an ability or capacity of something to be maintained or to sustain itself. It’s about taking what we need to live now, without jeopardizing the potential for people in the future to meet their needs (“What”). If an activity is said to be sustainable, it should be able to continue forever. Some people say it is easy to recognize activities that are unsustainable because we know it when we see it. Think of extinction of some species of animals, often due to the activities of humans. Or salt in our rivers due to changed land management practices. And at home, the amount of packaging you put in the bin that has to go into landfill. In addition to these, sustainability can be measured in things like our energy use and carbon footprint, solid waste generation, and even our food choices. Measuring your energy use and carbon footprint is something that every American needs to take time to do. This is very important because it puts in perspective how many Earth’s we would need to support human life if everyone lived like you. For most Americans, the...

...variations in bristle shape, size, and texture, as well as unconventional handle styles. The Manufacturing Process: Injection molding is one of the most common methods of shaping plastic resin into useful objects. The process involves heating pellets of plastic resin to melting point then injecting the molten resin into a mold. Molding the handles and head. The first step in manufacturing a toothbrush is to create the toothbrush handle. Simple, manual toothbrushes and more complex electric toothbrushes require a plastic handle, though the molds used to shape these different types of brushes are quite different. The injection-molding machine deposits liquid plastic into the mold and then pushes the handle out of the mold once the handle is solidified. Multi Injection. For multicolored brushes, there will be two-stage injection process as described below: When the pre-injection is completed, the mold slides open with the handles still attached to it. Then the mold rotates 180° and closes so that the brush handles now face another die / cavity which can inject different shape and different color on to the handles. EMM2512_ICA02_1 Bristling. After the handles are formed, a filling machine is used to attach the bristles. In modern toothbrushes, these are made from nylon or plastic. The filling machine pushes the bristles into holes in the head of the handle and then...

...Unit 3: Assignment Chapter 5 Delta Plastics Case 1. The different costs of quality that costs that Delta Plastics has been effected by are appraisal because Jose has to analyze the monthly quality report, internal because they rushed releasing the new product without quality testing and external because the if the customer receives a defective plastic product they will not want to buy any more and will tell their friends that it is a poor product. Delta Plastics traded off the prevention cost which would have been more time spent fine tuning the plastic so that they could release the new “Super Plastic” sooner ahead of potential competitors. George Chadwick was incorrect when he decided that more tests were not necessary. Because of that decision the new “Super Plastic” has 93 defective for cracks and 71 defective for air bubbles for the month compared to the Standard Material which had 41 defective for cracks and 55 defective for air bubbles. For the other three defective categories, two of the three were within a standard deviation of each other. 2. The quality control tool that I would use to analyze the monthly quality report would be the histogram. I would use it because it easily differentiates and visually presents the data. Between the two products there was a dramatic difference in the defects for cracks and air bubbles. The new “Super Plastic” had 93 products defective for cracks and 71 defective for air bubbles for the month. The Standard...

...key strategic issues he needs to consider. He could grow the company and enter into other segments of the business. This segment would be the plastics containers that would have potential. Other option is whether to acquire Continental Can Canada or not. The company generates $400 million in sales per year and it is the largest manufacturer in the Canadian region. That does not seem a whole lot. However, Continental’s USA business has estimated revenues of $1.3 billion which would double the size of Crown’s domestic operations. Also, Continental’s European operations generated estimated sales of $1.5 billion. Potential bidders for the acquisition are the major competitors of CCS. Avery is concerned about both options because they both have pros and cons. Entering the plastic can business segment would have the following pros: • Entering a new business segment, great for diversification • Decreasing shipping cost because of lighter weight • Made of natural resources • Plastic material can easily be formed/shaped Entering the plastic business segment would have the following cons: • Unknown business territory, no experience • Carbonation leaks after 4 month – major issue • Cannot be fully recycled Acquiring Continental Can Canada would have the following pros: • Double in size domestically, increase market share rapidly • Plastic container line would come from this factory • Expansion globally • Increasing bargaining power Acquiring Continental Can Canada would have...
