摘    要:采用Ar氛烧结碳化法在600℃、700℃、800℃及900℃下制备了基于氧化石墨烯(GO)/壳聚糖复合材料的超级电容器电极材料。通过XRD、SEM、FTIR及循环伏安等电化学手段,系统评价了碳化的GO/壳聚糖复合材料作为超级电容器电极材料的可能性。通过与文献报道的纯壳聚糖碳化材料的相关性能进行比较,结果表明:碳化GO/壳聚糖复合材料力学性能较纯壳聚糖碳化材料提高约67%,而且具有良好的电容器材料的性质。800℃碳化GO/壳聚糖复合材料样品的比电容达131 F/g,1 500次充放电后比电容保持率达97%。

关 键 词:氧化石墨烯  壳聚糖  超级电容器  力学性能  电学性能

Abstract:The carbonized graphene oxide(GO)/chitosan composites were prepared by atmosphere sintering in Ar atmosphere at 600℃, 700℃, 800℃ and 900℃. The carbonized GO/chitosan composites were characterized by XRD, SEM, FTIR and electrochemical station. The results indicate that the carbonized GO/chitosan composites exhibit the significant improvement (around 67%) in mechanical properties comparing with pristine chitosan. The specific capacitance of the carbonized GO/chitosan sample fabricated at 800℃ is about 131 F/g, the specific capacitance retention after 1 500 cycles is higher than 97%.
Keywords:graphene oxide  chitosan  supercapacitors  mechanical properties  electrical properties
