化学响应型形状记忆材料因其独特的响应方式而越来越受到重视。论述了化学响应型形状记忆材料研究进展,主要包括形状记忆聚合物、形状记忆复合物以及形状记忆凝胶等。根据其形状记忆的原理,将化学响应型形状记忆过程分为塑化回复过程、溶胀回复过程、溶解回复过程以及pH回复过程。塑化作用是溶剂分子与聚合物基体相互作用,降低高分子基体的玻璃化转变温度,实现形状记忆效应;溶胀效应是溶剂分子扩散进入聚合物内部使自由体积膨胀,释放出形变时存储的弹性能实现形状记忆效应;溶解回复型是可变相溶解后,通过受限弹性相回复实现形状记忆效应;pH回复是一定pH环境下产生的质子化作用促进材料内部链段运动性,驱使去质子化作用时存储的能量释放实现形状记忆效应。

Due to the unique response, chemoresponsive shape memory materials (SMMs) have attracted more and more attentions. Chemoresponsive SMMs which mainly include shape memory polymer, shape memory composite and shape memory gel, are reviewed in this paper. Based on the shape memory principles, chemoresponsive SMMs are divided into plasticization recovery SMMs, swelling recovery SMMs, soluble recovery SMMs and pH induced recovery SMMs. Plasticization, as the interaction between solvent molecules and the polymer matrix, reduces the glass transition temperature of polymer and realizes the shape memory effect. Swelling effect is the diffusion of solvent molecules into the polymeric network and induces the free volume of matrix to expand, shape memory is activated by releasing the elastic energy stored during the deformation of temporary shape. Soluble recovery means the constrained elastic phase recovers after switchable phase is soluble and the shape memory is achieved. For pHresponsive SMMs, protonation promotes the motion of the inner segment in a certain pH environment, which drives the energy stored at deprotonation release to achieve the shape memory effect.
