摘　　要：偶氮聚合物光致质量迁移行为是近年来国内外的研究热点之一,涉及到一系列有关光-物质相互作用的基本科学问题。研究偶氮聚合物微球的光致质量迁移行为,不仅为制备形状各向异性粒子提供了一种全新的途径,对研究和理解光致质量迁移这一复杂的多尺度运动行为也有重要意义。本文介绍了作者课题组近年来在偶氮聚合物光致质量迁移研究的相关工作,分析了在不同条件下微球的形变行为和内在机制,并展望了这一领域的发展趋势。Photoinduced mass transfer behavior of azo polymers has aroused extensive research interest in recent years, which involves a series of basic scientific problems about light-matter interactions and promising application prospects.Azo polymer microspheres can act as a unique type of isolated deformation unit to show photoinduced mass transfer behavior. The research in this area not only offers a novel method for the preparation of shape-anisotropic particles through photoinduced shape-manipulation,but also provides a valuable tool for studying the complex multi-scale motions of photoinduced mass transfer behavior.This article presents and summarizes the progresses in the photoinduced mass transfer and deformation of azo polymer microspheres in recent years.The deformation behavior and its intrinsic mechanism of azo polymer microspheres under different conditions are comprehensively discussed.A perspective of the future research and applications in this field is also presented.
