摘　　要：用旋转涂布法制得了PVA -H3PW1 2 O40 复合体系的光敏膜。研究了膜对光的响应情况 ,发现复合体系对光的响应情况与体系内各成份的浓度无关。光敏性的产生源于体系内PVA的 OH与钨磷酸阴离子中Oc的相互作用。The composite photosensitive film was prepared by spin coating method. The photochromism of the film was studied, the results indicating the reaction time of the film for light had no relation to the concentration of the composite. The photosensitivity resulted from the interation between the OH of PVA and the Oc of the anion.
