摘　　要：合成了一种新的带有光交联基团的电光聚合物， 其高分子基体是双酚Ａ 环氧树脂， 二阶非线性生色团对硝基苯胺和光交联基团肉桂酰氯都键接在高分子链上． 将聚合物溶解后旋涂成膜，对薄膜进行电晕极化． 极化的后阶段用紫外光照射， 使聚合物体系交联成网络结构， 形成生色团取向长时间稳定的聚合物电光薄膜． 用这种聚合物电光薄膜构成外部电光调制系统，A novel three dimensional electro optic polymer containing photo crosslinkable group was synthesized. 4 Nitroaniline and cinnamyl were introduced onto the polymer matrix of bis A epoxy as the electro optic chromophore and photosensitive chromophore respectively. A thermal stable polymeric electro optic film was prepared by spin coating, followed by the corona poling and photo crosslinking reaction in the late poling phase. An external electro optic measuring system based on the electro optic film was fabricated, by which the electric signals propagating on the coplanar waveguide were measured.
