刺激响应聚合物是近几年来研究的热点之一,这类聚合物能够感受外界刺激而发生响应,产生物理或化学性质的变化.金纳米粒子由于量子效应,具有良好的催化性质,因此有广阔的应用前景.但是在实际的应用中却常常面临易于团聚的问题,因此时常需要将其负载于载体之上.将刺激响应聚合物引入金纳米粒子催化体系之中,一方面可以发挥普通载体所能起到的分散作用,防止金纳米粒子团聚,另一方面也可实现可控催化,可以通过外界条件的改变来调控金纳米粒子的催化性能.本文综述了该体系近期的研究进展,从体系的构建方式、刺激响应类型等方面进行了论述,并对该体系的研究与应用进行了总结与展望.%Stimuli-responsive polymer has attracted much attention in recent years.This kind of polymer can respond to external stimuli and switch their properties.Gold nanoparticles have excellent catalytic properties which means a bright application prospect.However,gold nanoparticles are easy to aggregate in the application,and it will result in a remarkable decrease of catalytic property.So different carriers are usually required to immobilize gold nanoparticles.The introduction of the stimuli-responsive polymer into the catalyst systems of gold nanoparticles is a way to prevent the aggregation similar to other normal carriers,and at the same time a fascinating approach to controllable catalyst.This paper reviews recent research progress on this kind of catalyst systems,followed by the discussion of their fabrication,sensitivity and applications.Moreover,the development potential of this field is also discussed.
