摘要 基于偶氮苯聚合物的光致异构和光致取向特性,开展了双偶氮苯功能化聚合物薄膜表面微结构的“刻写”研究·利用两束相干光照射,在样品表面“刻写”出了亚微米量级的光栅结构;利用分步法在样品表面制作出了清晰的“三角格子”等花样微结构,证明了双偶氮苯功能化聚合物对于表面微结构的制作有较强的可操作性·通过对比单偶氮和双偶氮材料的实验结果,证明了双偶氮聚合物具有响应时间快、衍射效率高等特点,并由此讨论了偶氮苯聚合物薄膜表面微结构的形成机理及其偏振选择性· Based on photoisomerizations and photoinduced alignments of an amorphous copolymer containing azobenzene groups, the writing process of the surface microstructures was studied. Some pattern structures were written on the sample surface by irradiation with two coherent laser beams. The forming mechanism and the polarization selectivity of the microstructure on the polymer surface was discussed by contrasting the phenomenons of azobenzene and di-azobenzene during the experiment.
