摘要： 合成一种具有可逆光加工特性的偶氮聚电解质(PAA-AZ),用核磁、热分析、紫外-可见光谱、接触角及GPC等手段对其进行了结构和性能表征.PAA-AZ的旋涂膜用线偏振Ar+激光照射一段时间,在原子力显微镜(AFM)下观测其表面,膜表面形成了规整有序纳米尺寸的三维表面图案表面起伏光栅(起伏深度为100nm).用氦氖激光检测了PAA-AZ旋涂膜一级衍射效率与光照时间的关系.

关键词: 偶氮聚电解质, 可逆光加工, 表面起伏光栅

Abstract: The surface relief gratings(SRG) of azo polymers formed upon irradiation with an interference pattern of coherent light have attracted great attention recently. In this study, a novel photodynamic azo polyelectrolyte was synthesized by incorporating azobenzene units into poly(acrylic acid) backbone. The polymer structure and properties were characterized by 1HNMR, elemental analysis, GPC, TA, UV Vis and contact angle measurement. The spin coated films on glass substrates were prepared from DMF solutions of the azo polyelectrolyte. The atomic force microscopy image of the films, which were exposed to the interference pattern of p polarized Ar+ laser beams at 140 mW/cm2, showed that the synthesized azo polyelectrolyte possessed a good photodynamic property. Good quality SRG structures were clearly generated(the depth from peak to trough was 100 nm).

Key words: Azo polyelectrolyte, Reversible photo processing, Surface relief gratings
