PHOTOREFRACTIVE POLYMER COMPOSITION EXCELLENT IN PHASE STABILITY AND METHOD FOR PREPARING THE SAME

摘要

PURPOSE: Provided are a photorefractive polymer composition which has excellent photorefractivity and phase stability, and which shows easy processability, and a method for preparing the same. CONSTITUTION: The polymer composition consists of a photoconductive polymer for conducting the incident light; a linear, electrically optical(nonlinear optical) polymer for refracting an incident light; and an electric charge generator for generating an electric charge in responding to the incident light. The composition further comprises 40.00 wt% or less of plasticizer in order to increase a processability of mixture of the photoconductive polymer and the linear, electrically optical polymer into film. The contents of the photoconductive polymer, the linear polymer, and the generator are 5.00-95.00 wt%, 5.00-95.00 wt%, and 0.05-2.00 wt%, respectively.
