氧化石墨烯/壳聚糖复合薄膜材料的制备及其非线性光限幅效应的研究
Preparation of graghene oxide/chitosan composite films and investigations on their nonlinear optical limiting effect
摘要
Abstract
As a new kind of carbon nanostructured material, graphene and its derivatives have attracted extensive attention owing to their outstanding optical limiting (OL) properties. However, most of the current studies concentrate on liquid matrix. In this work, we use chitosan (CS) as matrix and homogeneously disperse graphene oxide (GO) into it to prepare GO-CS composite films. We comparatively study the different OL effects and mechanisms of GO in liquid and solid matrix. The results show that GO presents stronger nonlinear optical effect and weaker nonlinear optical scatter, which indicates that different from carbon nanotubes, GO may possess multi sort of nonlinear optical effects.关键词
