中文摘要： 形状记忆聚合物是一种新型智能材料，增加与具体应用环境相适应的功能特性已成为其进一步发展的大趋势。本项目提出将导电聚合物和形状记忆聚合物的特征结构结合于同一种材料中以获得本征导电的形状记忆聚合物的新思路，拟采用半互穿聚合物网络(IPN)技术来实现这一分子结构设计思想。通过乳液聚合和共聚合反应，使环氧形状记忆聚合物网络和导电聚苯胺大分子链形成双相连续、相互贯穿和强迫互容的有效连接，获得一种半IPN结构的本征半导体形状记忆聚合物。通过调控IPN结构中导电大分子链的聚集密度和掺杂程度来提高本征导电环氧形状记忆聚合物的电导率。基于形状记忆网络变形前后的能量状态等特征来研究导电和形状记忆两种功能之间的协同效应，分析材料的构效关系，从而揭示形状记忆聚合物本征导电功能化机理。本项目为形状记忆聚合物导电功能化研究提供了新途径，将为形状记忆聚合物其它功能化研究提供理论指导。

英文摘要： Shape memory polymer is a novel smart material, and the general trend for its further development is to add functional characteristics appropriate to specific application environment. A new idea is suggested in this project that characteristic structures of conductive polymer and shape memory polymer are combined into one polymer to obtain intrinsic conducting shape memory polymer. This idea is carried out by half-interpenetrating polymer network (IPN) technology. In order to obtain an intrinsic semi-conducting shape memory polymer material with semi-IPN structure,conducting Polyaniline molecular chains and epoxy shape memory polymer network is connected effectively through dual-phase continuous,interpenetrating and forced compatibility by emulsion polymerization reaction and copolymerization reaction. Conductive properties of the epoxy intrinsic conducting shape memory polymer is improved significantly by adjusting density and doping level of large conducting Polyaniline molecular chains. The synergistic effect between conductivity property and shape memory effect is studied based on energy condition before and after shape changing of shape memory network and other characteristics, and the relationship between structure - properties is analysized. According to the aboves, mechanism of multi-function on shape
