In this paper, we report a facile low-cost synthesis of the chitin and chitosan-based hybrid nanocomposites for supercapacitors. The chitosan and chitin based hybrid composites functional group analysis, structural, optical and morphological properties were characterized using FTIR spectroscopy, Raman spectroscopy, UV-vis spectroscopy and scanning electron microscopy (SEM), respectively. Specific capacitance values of hybrid composites were calculated using cyclic voltammetry, electrochemical impedance spectroscopy and galvanostatic charge–discharge analysis. The hybrid composites asymmetric supercapacitor performance was perceived in the range of −0.2 to 1.0 V. The specific capacitance value was achieved at 542.63 F g−1 at current density value of 0.1 A g−1 for CH-GO-ZnO/PANI hybrid composites. The prepared hybrid nanocomposites exhibit good supercapacitive performance and long-term cycle stability. These results demonstrate the potential of the CH-GO-ZnO/PANI hybrid nanocomposites as a high-performance supercapacitors.
在本文中，我们报道了一种用于超级电容器的基于几丁质和壳聚糖的混合纳米复合材料的简便低成本合成方法。分别使用傅里叶变换红外光谱（FTIR）、拉曼光谱、紫外可见光谱和扫描电子显微镜（SEM）对基于壳聚糖和几丁质的混合复合材料的官能团分析、结构、光学和形态特性进行了表征。使用循环伏安法、电化学阻抗谱和恒电流充放电分析计算了混合复合材料的比电容值。在-0.2至1.0V范围内观察到混合复合材料不对称超级电容器的性能。对于CH-GO-ZnO/PANI混合复合材料，在电流密度值为0.1A g−1时，比电容值达到542.63F g−1。所制备的混合纳米复合材料表现出良好的超级电容性能和长期循环稳定性。这些结果证明了CH-GO-ZnO/PANI混合纳米复合材料作为高性能超级电容器的潜力。
