摘要
采用原位聚合法制备不同摩尔比的PANI/MoS_2纳米复合材料。通过X射线衍射、红外光谱、透射电镜等手段,对所制备的材料进行了结构和微观形貌的表征,结果表明:所制备的聚苯胺呈现棒状纳米纤维包覆在卷曲的纳米鳞片MoS_2片层上形成了PANI/MoS_2纳米复合材料。通过循环伏安法、恒流充放电等测试手段对材料的电化学性能进行了研究,结果表明:在不同电流密度下PANI∶MoS_2=1∶0.1的二元复合物比电容明显高于纯聚苯胺,在1 A/g时PANI∶MoS_2=1∶0.1的二元复合物的比电容值可达942.5 F/g,相比于同电流密度下的PANI的400.5 F/g的高出一倍。表明适量的MoS_2的掺入有助于提高PANI电极材料的电化学电容特性。
PANI/MoS2 nanocomposites with different molar ratios were prepared by in-situ polymerization. The structure and microscopy of as-prepared materials were characterized by X-ray diffraction（XRD）, FTIR spectroscopy, and transmission electron microscopy（TEM）. The results of analysis indicated that the prepared polyaniline exhibited rod-like nanofibers coated on the curled nanoscale MoS2 sheet. The electrochemical properties of the material were studied by cyclic voltammetry（CV） and galvanostatic charge-discharge（GCD） tests. The results showed that the specific capacitance of PANI：MoS2=1：0.1 was significantly higher than that of pure polyaniline at different current densities. The specific capacitance of the PANI：MoS2=1：0.1 composites reached 942.5 F/g, which was double that of PANI（ 400.5 F/g） at the current density of 1 A/g. It showed that the proper amount of MoS2 incorporation helped to improve the electrochemical capacitance characteristics of the PANI electrode material.
