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 polymers are one of the hot topics studied in recent years. These polymers can respond to external stimuli and produce changes in their physical or chemical properties. Due to the quantum effect, gold nanoparticles have good catalytic properties, so they have broad application prospects. However, in practical applications, it often faces the problem of easy reunification, and therefore, it often needs to be loaded on the carrier. The stimuli-responsive polymer is introduced into the catalytic system of gold nanoparticles. On the one hand, it can play the role of ordinary carriers can play a role in the dispersion, to prevent gold nanoparticles agglomeration, on the other hand can also be controlled catalysis can be changed by external conditions To regulate the catalytic properties of gold nanoparticles. This article summarizes the recent research progress of the system, discusses the construction of the system, the type of stimulus response and so on, and summarizes the research and application of the system.
