中文摘要： 本项目致力于微波驱动下具有快速形变回复性能的聚离子液体/聚乙烯醇互穿网络形状记忆聚合物的研究。拟设计具有高介电性能的咪唑类和季铵类离子液体单体(ILM），通过原位聚合法将ILM引入到交联聚乙烯醇（PVA）基体中形成具有互穿网络结构的形状记忆聚合物（SMPs），考察微波辐照下材料的形状记忆性能。与该领域当前研究的靠添加无机填料实现光、电、磁等远程响应的SMPs相比，本项目研究的材料是完全基于聚合物的可非直接接触驱动的形状记忆材料，能有效避免无机与有机材料间相容性差及受热不均匀、回复速率慢等问题，进而获得微波作用下可快速回复、性能优良的SMPs。系统研究离子液体聚合物骨架、阳离子基团的种类、互穿网络的交联密度、组成的比例及辐射功率等条件对产物结构、性能的影响；详细研究所制备材料合成条件与性能间关系，实现微波作用下结构稳定、回复性能优异的SMPs制备。

英文摘要： The aim of the present research is to desgin and sythesize microwave induced shape memory polymers (SMPs) based on poly(ionic liquid)/poly(vinyl alchohol) having fast recovery properties. We intend to design different kinds of imidazolium-and quarternary ammonium- based ionic liquid monomer (ILM) with high dielectric properties.The ILM will be introduced into crosslinked poly(vinyl alcohol) network using insuit polymerization to prepare SMPs having interpenetrating polymer networks. After that we will study the shape memory effect under microwave irradiation and the mechanism behind it. Compared with the present ligh, electricity and magnetic field remotely induced SMPs prepared by adding inorganic filler, the present studied material also can be remotely controlled, which completely comprises polymers and could effectively avoid the incompatibility between oragnic an inorganic materials, non-uniform heating or slow recovery rate. The project will systematically study the effect of several different factors on the products structre and properties, such as polymer backbones, the kind of cation groups, crosslinking density and the composition of interpenetrating polymer networks or the microwave irradiation power. We will detailedly study the relationships between sythesis condition and products properties, real
