High temperature polymers
Introduction: Polymers or most ordinarily known as plastics is used abundantly in a wide range of applications. In fact, they are seen almost anywhere in our daily lives. Polymers are those substances that are composed of individual monomers cross linked with long chains and bonds. They are composed of a long chain of carbon backbone constituted with other elemental contributions such as O,N,S,F,…

Before the body part is replaced, compatibility of the biomaterial and the living tissue is of great consideration (Ratner 2004). Biocompatibility is the acceptance of the synthetic biomaterial by the immediate and surrounding tissues and by the body generally (Paul & Kelvin 2009). Appropriate host response is shown by lack of blood clotting, normal heating and resistance to bacterial…
