| 摘 要： | 合成了一种主链含偶氮生色团的线性聚酯,用核磁共振、热分析、紫外-可见光谱、红外光谱、GPC等方法对其结构进行了表征.该聚合物膜在线偏振激光的作用下,光致取向形成的双折射各向异性Δn可达0.07.聚合物的旋涂膜经干涉的P偏振488nmAr+激光照射60min后,得到了规则的正弦表面起伏光栅,光栅的一级衍射效率约为18%.

| Abstract: | Anovel polyester with a high density of azobenzene groups in the main chain was synthesized by ester-interchange reaction of ethyl-4-4-(2-hydroxyethyl)ethylamino]-phenylazobenzoate. The structure and properties of the azo polyester were characterized by 1HNMR, GPC, TA, UV-Vis and others. On irradiation with a linearly polarized laser beam, birefringence was induced in the azo polymer film to the level of 007. Surface profile grating was optically inscribed upon exposure to an interference pattern of Ar+laser beam at modest intensities. The first order of diffraction efficiency of the surface relief grating was up to 18%. |
