摘要

Abstract

Photoinduced reversible liquefaction and solidification of polymers enable processing and healing of polymers with light. Some azobenzene-containing polymers (azopolymers) exhibit two types of photoinduced liquefaction properties: photoinduced reversible solid-to-liquid transition and directional photofluidization. For the first type

light switches the glass transition temperature (

) values of azopolymers and induces reversible solid-to-liquid transitions. For the second type

polarized light guides solid azopolymers to flow along the polarization direction. Here

we compare the two types of photoliquefaction and discuss their mechanisms. Recent progresses and applications based on photoliquefaction of azopolymers are also highlighted.
