Natural and synthetic polymers pdf

1. Introduction. Many of the substances we use in everyday life are made from “Polymer” chains. A polymer is a very long molecule made up of many smaller molecules called monomers. There are two types of polymers: Natural and synthetic. The products from natural sources have become an integral part of human health care system because of some side effects and toxicity of synthetic drugs. Applications of natural polymers in pharmacy are comparable to the synthetic polymers and they possess wide scope in food and cosmetic menuggboots.top by: Natural polymers These polymers are found in nature generally from plants and animals sources. Examples are proteins, cellulose, starch, resins. Semi-synthetic polymers These polymers are obtained from natural polymers by simple chemical treatment to change the physical properties of natural polymers like Starch, silicones.

There are two types of polymers: synthetic and natural. Synthetic polymers are derived from petroleum oil, and made by scientists and engineers. Examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy. Natural polymers occur in nature and can be extracted. They are often water-based. Dr. Kumbar is serving as a reviewer for more than 25 journals in the field of biomaterials, drug delivery and tissue engineering. He has recently edited a book “Natural and Synthetic Biomedical Polymers” Elsevier Science & Technology, ISBN: Book Edition: 1st Edition. Natural polymers (from the Greek poly meaning “many” and meros meaning “parts”) are found in many forms such as horns of animals, tortoise shell, shellac (from the lac beetle), rosin (from pine trees), asphalt, and tar from distillation of organic materials. One of the most useful of the natural polymers was rubber, obtained from the sap. Organic Polymers Synthetic and Natural A polymer is a high molar mass molecular compound made up •Cellulose •Rubber Synthetic polymers •Nylon •Dacron •Lucite Silverstone®: polytetrafluoroethylene Tyvek. 3 The simple repeating unit of a polymer is the monomer. Homopolymer is a polymer made up of only one type of. 1. Introduction. Many of the substances we use in everyday life are made from “Polymer” chains.

Examples are proteins, cellulose, starch, resins. Semi-synthetic polymers These polymers are obtained from natural polymers by simple chemical treatment to change the physical properties of natural polymers like Starch, silicones. Scaffolds generated from natural polymers 9, synthetic polymers, or by removing the cellular components from xenogeneic tissues 1 have been used with and without prior cell-seeding to support and guide the in-growth of cells. Natural Matrices One option for creating tissue scaffolds is to use extracellular matrix (ECM).
