| 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%。 |

| 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%. |
