摘　　要：偶氮聚合物光致表面起伏光栅研究涉及一系列光和聚合物相互作用的基本科学问题,是近年来国内外研究的热点。将软刻为代表的微加工技术和偶氮表面起伏光栅光刻方法相结合,为表面起伏光栅的制备和应用开辟了新的途径。本文综述偶氮化合物表面起伏光栅光刻和软印刷复制等方面的最新研究进展,并介绍功能性光栅结构和器件在太阳能电池、液晶定向层及光栅传感器领域的应用。Photoinduced reversible surface-relief-gratings （SRGs） on the azo polymer films have aroused extensive research interests in recent years. Soft-lithographic methods have been well-known as a powerful tool for preparing various nano/microstructures. Combining photo-fabrication of SRGs and soft-lithographic methods has offered a new processing method to develop SRGs with various functional materials. This new approach can lead to potential applications of SRGs in solar cells, liquid crystal display and optical sensing. This article reviews the research progresses in the SRG photo-fabrication, the soft-lithographic duplication methods and applications. Related background and literature are given at the same time and discussed in some details.
