刺激响应性高分子由于能对外界的电、磁、热、光等刺激做出感应进而发生物理性质的明显改变, 受到越来越多的关注。在不同的外部刺激中,光刺激具有清洁易获得、远程操控性强、反应调控精准迅捷等特点。
基于光刺激的这些优势, 在高分子中引入特定的感光基元可以使聚合物微结构对光产生响应性变化,从而赋予其特定的性质和用途。 
Stimulation-responsive polymers have attracted more and moreattention due to their ability to respond to external electrical,magnetic, thermal, light and other stimuli, and then make obviouschanges in physical properties. Among different external stimuli,light stimulation has the characteristics of clean and easy access,strong remote control, accurate and fast response regulation.
Based on these advantages of light stimulation, theintroduction of specific photosensitive elements into the polymercan make the polymer microstructure responsive to light, thusendowing it with specific properties and uses.
