Abstract:
As a kind of “smart” functional material, shape memory polymers (SMPs) have good biocompatibility, large deformation ratio, adjustable range of deformation temperature, easy processing, and possible biological degradability, and they have drawn much great attention in the field of biomedical research and application in recent years. The research and application of SMPs in biomedical field are reviewed, for example, in orthopaedic fixed materials, drug release system, surgical equipment, suture and tissue engineering. Further perspectives are discussed for SMPs, and their research progress and relevant mechanism are briefly introduced meanwhile.
