Experimental Studies of Photorefractive Polymers

这项研究将对聚合物光折变材料中的光折变效应的机理，特别是光导的基本物理，有了详细的了解。聚合物中的电荷捕获、电光响应和介电弛豫。这一知识将允许合成和制造适用于广泛应用的改进的光折变聚合物，尤其是那些将利用聚合物相对较低的成本以及与结晶材料相比容易和灵活加工的那些材料。所获得的洞察力也将有益于对聚合物光折变器件的性能进行建模。

This research will gain detailed understanding of the mechanism of the photorefractive effect in polymer photorefractive materials, particularly the underlying physics of photoconduction, charge trapping, electro-optic response, and dielectric relaxation in the polymers. This knowledge will permit the synthesis and fabrication of improved photorefractive polymers suitable for use in a wide range of applications, particularly those which will take advantage of the relatively low cost and the ease and flexibility of processing of polymers as compared to crystalline materials. The insight gained will also be beneficial in modelling the performance of polymer photorefractive devices.
