具有形状记忆功能高分子材料的研究进展

第 1 页 共 9 页具有形状记忆功能高分子材料的研究进展摘 要：本世纪以来，随着高分子合成以及改性技术与高分子学理论的迅猛发展，形状记忆高分子材料正快速地渗透到我们的日常生活中，成为了一种不可或缺的材料。本文通过查阅相关的文献，对该材料的研究发展过程、应用现状进行综述，由于形状记忆高分子材料种类丰富，其中着重阐述热致型形以及光致型形状记忆高分子材料。相关研究发现热致型形状记忆材料在医疗领域的应用存在可能会对人体机能造成破坏的缺点。本文认为将热致型与光致型形状记忆材料结合使用可以克服这个缺陷，从而提升形状记忆材料的性能。关键词：形状记忆；记忆效应；热致型；光致型Abstract ： Since the beginning of this century,with the rapid development of polymer synthesis and modification technology and polymer theory, shape memory polymer materials are rapidly infiltrating into our daily life and become an indispensable material. This paper reviews the research and development process and application status of this material by consulting relevant literature. Due to the variety of shape memory polymer materials, the thermal induced polymer and photo induce polymer polymer materials are emphasized. Through related research and discussion, it is found that the application of thermally induced shape memory materials in the medical field may have the disadvantage of causing damage to human body function. I believe that the combination of thermal induced and photo induced shape memory materials can overcome this defect. Thereby increasing the use scene of the shape memory material.Key words ： shape memory ； memory effect ； thermal induced polymer ； photo induced polymer1 引言1.1 形状记忆高分子材料的概念 判断一类高分子材料是否为形状记忆高分子材料，即在于看这类材料是否能第 2 页 共 9 页产生记忆效应，这是形状记忆高分子材料最核心的本质。一高分子聚合物在起初被赋予一定的形状后，固定其形状得到它的“初始态”。随后对其施加一定的外力，让它...
