摘要
Polyurethane is an excellent and widely used polymer material.In synthesizing polyurethane,the structure of soft and hard segments in polyurethane could be adjusted,which can obtain better properties than other polymer materials,such as good mechanical properties and biocompatibility.In recent years,due to their excellent chemical stability,biocompatibility,and low cytotoxicity,polyurethanes have been widely used for biomedical applications.To solve the problems of degradation and recycling,the development of bio-based polyurethane has also become a current hot spot.This paper summarizes the research progress and applications of polyurethane materials for dressings,skin sensors,orthopedics,and cardiovascular.It also looks forward to the future development of polyurethane medical materials.
