Polymer

Polymers are all around us, a fact that we cannot deny. Polymers are used by everyone of all ages. Man has used natural polymers throughout history, but it is only in the last 60 years that we have been able to make our own synthetic polymers. Polymers have been used vastly in many industrial applications until now. However, like any other organic compounds, polymer burn readily in presence of oxygen, and generally thermoplastics are worse than thermoset materials. The flammability of polymers can

Conductive polymers are a specific section under the broad range of polymers, that have the ability to effectively conduct electricity. They were discovered by accident in a lab by Hideki Shirakawa in 1974, yet their potential applications were not understood until early 2000s. They are made by doping with n-type and p-type which forces electrons to move throughout the material which normally would not happen because of a polymer molecular structure. They provide many advantages over metals because

SMART POLYMERS Polymer scientists have been trying hard to mimic this feature for the last twenty years creating called smart polymers. These are defined as polymers that go through reversible large, physical or chemical changes in response to small external changes in the environmental conditions, such as temperature, pH, light, magnetic or electric field, ionic factors, biological molecules, etc. Smart polymers have very promising applications in the biomedical field as delivery systems of therapeutic

learn, learn and relearn until my end. My decision to apply for MS polymer engineering has emerged, both from my passion for research and my aspiration to understand the language of energy generation. I felt polymer engineering footholds the entire world. This makes it one of the most challenging fields of the present generation. It has the power to create novel designs in the field. I keenly wish to contribute more towards the polymer engineering to this field by acquiring the practical knowledge and

Experiment 1: Release of Aspirin from a Polymer Matrix Summary Firstly, aspirin was weigh to 0.25g which was then dissolved in 100cm3 of distilled water by heating to >80°C using a hotplate. 2.0g of agar was added while stirring and was heated till dispersed, giving almost clear solution. The temperature was control so as not to overheat the agar. The agar was left to cool in an ice bath. Using a hollow cylinder, the agar was cut to approximately 4.0g (the exact weight of the agar was recorded).

The evolution of polymers throughout the past has been very impressive. Many industries depend very heavily on polymers. A polymer is a long molecule consisting of many similar or identical building blocks linked by covalent bonds ( ). Polymer means many monomers. A monomer is a simple compound whose molecules can join together to form polymers ( ). Polymerization is the process of connecting these monomers together and creating large macromolecules of different sizes and shapes ( ). Advances

 Polymers they are combined form small units of compound having low molecular weight, as a wall is made up of bricks.  The word ‘polymer’ is taken from two Greek words poly states many and (mer) means unit or part.  The term polymer is defined as very large molecules having high molecular mass. These are also referred to as macromolecules, which are formed by joining of repeating structural units on a large scale.  The repeating structural units are derived from some simple and reactive molecules

A polymer is a large molecule consisting of many smaller subunits known as monomers. There are different types of polymers and many uses for all of them. Even though people may not realize it polymers play an essential role in our everyday life. For polymers range from plastics, PVC, and Styrofoam to key structures in the human body like DNA and proteins which are key components to the human body that makes it possible for each of us to live and be unique. So with out polymers in our body we would

Synthetic vs Natural Polymers in Conditioning Shampoos Introduction and Thesis Cosmetics have been used for thousands of years to enhance the visual appearance of people, either through ritualistic or aesthetic motivations. With the turn of the 20th Century, the growing trend of the film industry caused an uprising in the commercialism of cosmetic products. This coincided with the increasing development in the chemistry industry, to accommodate the multi-billion dollar industry which is present today
