中文摘要:
      聚乙二醇(PEG)是一种结晶完善且具有良好水溶性的热塑型聚醚高分子,其分子链结构在无定形态及结晶态间相互转变的特性符合形状记忆材料对可逆形变结构的要求,因此广泛应用于形状记忆高分子材料的研究。文中综述了近年来聚乙二醇在形状记忆聚合物、形状记忆水凝胶、形状记忆复合材料等高分子材料中的应用研究进展,阐述了聚乙二醇链结构与材料形状记忆特性及不同刺激响应性之间的关系,并特别强调了聚乙二醇与水的氢键作用对水诱导响应型形状记忆特性的重要性,对低毒且生物相容性好的聚乙二醇基形状记忆高分子材料在生物医学领域的应用进行了展望。
英文摘要:
      Polyethylene glycol (PEG) was a kind of thermoplastic polyether polymer with perfect crystal and water solubility. According with requirement of reversible deformation structure of shape memory materials, PEG was widely applied in shape memory polymer material based on the changeable molecular chain structure between amorphous state and crystalline state. The progress in the application of PEG to shape memory polymer, shape memory hydrogel and shape memory composite materials in recent years was reviewed in this paper. The relationship between PEG molecular chain structure, shape memory effect and the response to various stimuli was demonstrated and the importance of hydrogen bonding interaction of polyethylene glycol with water to water induced shape memory property was highlighted. Biomedical applications of PEG based shape memory polymer materials with low toxicity and good biocompatibility were also prospected.
