摘要
近几年来,人们在聚合物中观察到了光折变效应。与无机材料相比,聚合物材料具有较大的电光响应、高的破坏阈值和低的介电常数,并且容易加工成形。所以它显示出光明的应用前景。本文描述了聚合物光折变的研究方法,并综述了迄今为止已经报道的理论和实验研究结果。
In the past few years, the photorefractive effect has been observed in polymeric materials. Compared to inorganic materials, polymeric materials have larger electro-optical response, lower dielectric constant, and higher damage threshold, and are easier to be processed. They, therefore, have bright future in applications. In this paper, the methods of studying photorefractive effect in polymers are described, and the theoretical and experimental results reported up to now are reviewed.
