Abstract
In order to satisfy medical requirements, several novel bioelastomers were prepared based on biocompatible acid and alcohol. These polyester typed bioelastomers displayed excellent elasticity and adjustable biodegradation capability and fine biocompatibility. However, due to the lack of crystallization, the tensile strengths of these bioelastomers were low. The nano-hydroxyapatite and carbon-nanotube were separately incorporated into these elastomers. As a result, their strengths were prominently improved. The biocompatibility of nano-reinforced bioelastomers was also checked and illustrated. A positive cell compatibility endowed by nano-particles was founded. The industrialized world is currently highly dependent on fossil fuels as a source of energy for industrial processes and for the chemical production of structural materials. The worldwide research on chemicals originated from renewable agricultural and biomass feedstock had been progressing actively during the past few decades. In order to provide the solution for rubber resource crisis, the concept of Bio Engineering Elastomer (BEE) is firstly put forward in this lecture. The definition and meaning of BEE are demonstrated. A series of novel chemically synthesized BEE with excellent performance by authors are also reported.
