形状记忆高分子材料（SMPs）作为一种新型功能材料具有生物相容性好、形变率大、形变温度可调、易于加工、可引人生物降解组分等特点，近年来，特别是在生物医药领域，SMPs已成为研究人员广泛关注的焦点之一。根据SMPs的功能及其应用研究现状，着重综述了近年来SMPs在矫形固定材料、药物缓释体系、手术缝合、微创医疗器械以及组织工程等生物医学领域的主要研究和应用，并展望了SMPs在生物医学领域未来的研究方向和前景，同时，简要介绍了SMPs的发展概况及其具有形状记忆效应的原理。
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.
