摘　　要：聚醚砜膜凭借其优异的综合性能被广泛用于先进分离与生物医用领域.然而,随着各领域对分离过程可控性以及分离精度要求的提高,目前商业化聚醚砜膜越来越难满足现实所需.因此,研究与开发可以感知和响应环境刺激,改变其特性的环境敏感聚醚砜膜是近年来科研人员关注的热点.本文根据刺激响应信号的种类,分别介绍酸碱敏感膜、离子敏感膜、热敏感膜、光敏感膜等在不同领域的潜在应用,以及刺激信号-膜结构响应-功能的关系,并对未来的环境敏感聚醚砜膜研究方向提出展望.Polyethersulfone(PES)membranes have been widely used in advanced separation and biomedical fields due to their excellent comprehensive properties.However,with the increasing needs for separation accuracy and the controllability of separation process in different fields,it is more and more difficult for commercial polyethersulfone membranes to meet the actual needs.Therefore,researches and developments of stimuli-responsive PES membranes that can sense and respond to environmental stimuli and change their characteristics,have always been attract much attentions for the researchers.According to the types of stimulus response signals,this article introduces acid-base sensitive membranes,thermal-responsive membranes,ion-responsive membranes,and light-responsive membranes,as well as their applications in different fields,and illustrates the interdependence of stimulus signals-membrane structure response function applications.Then,we also put forward the prospects for future research direction of environmentally sensitive PES membranes.
