Polymeric Biomaterials (Mingyu Li z3369978) The use of polymers in biomedical applications is now widely accepted and they are termed with the generic name of polymeric biomaterials. A biomaterial can be defined by their function as a material in contact with living tissue that used to the treatment of disease or injury‚ and to improve human health by restoring the function of tissue and organs in the body.x Polymeric biomaterials in medicine include surgical sutures‚ drug delivery vectors‚ orthopedic

Introduction Polymers are large macromolecules composed of many small repeating subunits (monomers) connected via covalent bonds. Both natural and synthetic polymers are created via polymerization of these small molecules (Chemistry 144 Writing Assignment information sheet). The chosen polymer‚ polytetrafluoroethylene (PTFE) in the form of Teflon®‚ is a synthetic fluoropolymer of tetrafluoroethylene (Wikipedia‚ 2015)‚ and is one of the most well-known brand names for PTFE based formulas‚ owned by

developing synthetic replacements for rubber. Two primary motivating factors prompted their research. First‚ the war effort required most of the available rubber for building equipment. Second‚ the price of rubber was unstable and it fluctuated frequently. Developing an alternative to rubber could solve both of these problems. At first‚ their goal was to develop a durable elastic strand based on synthetic polymers. In 1940‚ the first polyurethane elastomers were produced. These polymers produced millable

Spandex fibers were first produced by Farbenfabriken Bayer. He was a pioneer in polymer chemistry and in 1952 earned a German patent for his synthesis. The final development of spandex was produced by scientists at Du Pont and the U.S. rubber Company. Du Pont used the brand name Lycra. They soon began manufacturing in 1962. Du Pont is the world’s leader in spandex production. Spandex development first started in during World War II as a substitute for rubber. Since rubber was being used for the
