摘要
近年来,聚合物光折变材料越来越受到人们的关注,因为与无机材料相比,聚合物材料有较高的电光系数,较高的光损伤阈值,低的直流介电常数,而且易于加工,所以光折变聚合物材料显示出光明的应用前景。文中介绍了光折变产生的简单的机理,以及目前国际上所研究的各类材料及发展状况。
This review presents the current status of the field on photorefractive polymers and provides a brief summary of reported polymeric PR materials. Here the four necessary elements of photorefractivity are described and also we introduce the structures and properties of the three classes of PR polymer materials: doped materials based on nonlinear optical polymer hosts, doped materials based on chargetransporting polymers and fullyfunctional polymers. The advantages and disadvantages of kinds of PR polymer materials are presented. We compare the PR polymers with the inorganic crystals, evaluation is presented with future prospects.
