羧甲基纤维素/石墨烯柔性复合材料的制备及其电化学性能
Preparation and Electrochemical Properties of Carboxymethyl Cellulose/Graphene Flexible Composite Materials
摘要
Abstract
Using cellulose derivative carboxymethyl cellulose(CMC)and graphene oxide(GO)as raw materials,a CMC/reduced graphene oxide(rGO)flexible composite with layered structure was prepared by a combination of casting curing and reduction technology.The effects of GO addition on the micro structure,functional group structure,thermal stability,and electrochemical properties of the composite were investigated.The results showed that GO significantly enhanced the surface roughness of CMC membrane.After reduction treatment,the thermal stability of CMC/rGO flexible composite was significantly improved,exhibiting ideal electrochemical characteristics of electric double-layer.With the increase of doped GO content,the electrochemical performace was improved accordingly.When the current density was 1 mA/cm2,the areal specific capacitance of CMC/rGO-40%flexible composite could reach 129 mF/cm2(mass specific capacitance was 80.6 F/g),and when the current density increased to 2 mA/cm2,the areal specific capacitance remained 72.7%(93.8 mF/cm2).Meanwhile,the equivalent series resistance of the composite material was only 0.58 Ω,which provided a theoretical and data basis for the application of cellulose-based materials in the field of flexible electrodes.关键词
