摘要
聚电解质凝胶是在聚合物网络结构中含有化学键结合的离子化基团的水凝胶。有些聚电解质水凝胶在施加电场的电解质溶液中能发生形变。本文叙述了对电场刺激发生响应的聚电解质凝胶的发展、响应机理,以及在人工肌肉、自动开关元件、药物释放体系方面的应用,并指出将其应用于组织工程的可行性。
Polyelectrolyte gel consists of a crosslinked polymer network with ionizable groups and a liquid phase. A kind of hydrogel exhibits a continuous or discontinuous volume change in an electrolyte solution by applying a dc electric field. The development of hydrogels responding to electric field was introduced. Several kinds of mechanism of polyelectrolyte gels responding to electric field were introduced in this article. This kind of hydrogel presents a number of potentially useful possibilities for robotics, artificial muscles, large-motion actuators, microvalves for drug-delivery systems. It is feasible that polyelectrolyte gel can be used in tissue engineering.
