Shape memory polymers(SMPs)are a class of functional"smart"materials that have shown bright prospects in the area of biomedical applications.The novel smart materials with multifunction of biodegradability and biocompatibility can be designed based on their general principle,composition and structure.In this review,the latest process of three typical biodegradable SMPs(poly(lactide acide),poly(ε-caprolactone),polyurethane)was summarized.These three SMPs were classified in different structures and discussed,and shape-memory mechanism,recovery rate and fixed rate,response speed was analysed in detail,also,some biomedical applications were presented.Finally,the future development and applications of SMPs are prospected:two-way SMPs and body temperature induced SMPs will be the focus attension by researchers. |
