摘要
环境响应型吸水树脂面对外界刺激时能够快速产生响应,物理结构和溶胀性能迅速发生变化,有望应用于人造肌肉、药物控释载体、吸附分离、细粒煤脱水等领域。该文综述了近年来环境响应型吸水树脂的研究进展。首先,简述了环境响应型吸水树脂的结构与性质。接着,重点介绍了4类不同响应类型(温度、pH、盐及磁响应)吸水树脂的响应机理、研究水平及应用现状。最后,总结了环境响应型吸水树脂在面向应用的研究过程中要解决的关键科学问题,并提出制备具有多重响应机制并兼顾刺激响应特性与机械性能的吸水树脂,可加快其由实验室基础研究向实际工业应用过渡和成果转化的进程。
Environmentally responsive superabsorbent resins can produce rapid response in the face of external stimulation and make changes in physical structure and swelling performance,which are expected to be applied in artificial muscles,drug controlled release carriers,adsorption and separation,fine coal dehydration and other fields.The recent research progress of environmentally responsive superabsorbent resins is introduced.First,the structure and properties of environmentally responsive superabsorbent resins are described.Subsequently,the response mechanism,research level and application status of temperaturesensitive superabsorbent resins,pH-sensitive superabsorbent resins,salt-sensitive superabsorbent resins,and magnetic superabsorbent resins are mainly discussed.Finally,the key scientific problems existing in the application-oriented research of environmental responsive superabsorbent are summarized.It is pointed out that the preparation of superabsorbent resin with multiple response mechanisms and mechanical properties can accelerate the transition from basic laboratory research to practical industrial application.
