形狀記憶高分子材料已經(jīng)成為一種新型的生物醫(yī)用智能材料，它能夠根據(jù)不同應(yīng)用進(jìn)行性能設(shè)計(jì)，滿足生物醫(yī)學(xué)領(lǐng)域?qū)Σ牧隙喙δ艿囊�求。基于不同的�?yīng)用，形狀記憶聚合物材料可以提供適合的功能例如形狀展開(kāi)功能，形狀固定及回復(fù)功能，形變回復(fù)率及回復(fù)力可控的性能等。形狀記憶高分子材料可以通過(guò)多種刺激例如熱，光，電，磁等方式被激發(fā)實(shí)現(xiàn)其生物醫(yī)學(xué)功能。這些刺激可以通過(guò)直接接觸或遙控的方式激發(fā)材料的性能。形狀記憶高分子材料也可以經(jīng)過(guò)設(shè)計(jì)具有生物降解性能，生物相容性等。本文首先介紹形狀記憶聚合物材料的結(jié)構(gòu)原理、性能及分類，并在此基礎(chǔ)上根據(jù)不同生物醫(yī)學(xué)領(lǐng)域的應(yīng)用進(jìn)行總結(jié)，同時(shí)針對(duì)不同形狀記憶性能在生物醫(yī)學(xué)領(lǐng)域的應(yīng)用進(jìn)行探討；最后對(duì)形狀記憶聚合物材料的生物力學(xué)性能、滅菌方式對(duì)材料性能的影響進(jìn)行總結(jié)。

Abstract:

Shape memory polymer has been a new bio-medical smart material. The performances of shape memory polymer can be tailored to meet the multi-requirements of biomedical area. Base on different applications, shape memory polymer can display a deployable property, shape fix and recovery property and controllable shape recovery velocity and shape recovery force. Many triggers can be used by direct or remote way to active the shape memory properties such as heat, light, electronic, magnetic to achieve the biomedical functions. The shape memory polymers also can be designed to get the biodegradability and biocompatibility. This paper will review the structure， properties, classification of shape memory polymers and summary the biomedical applications based on different medical field and shape memory performances.
