不同方法制备聚苯胺/MoS_2复合材料及其电容性能

结合Li插层法制备的单层MoS2,分别采用溶液法和乳液法原位聚合制备了聚苯胺/MoS2复合材料。由FT-IR光谱对其结构进行表征,由电化学工作站测试其做电容器电极材料的电化学性能。结果表明,相同MoS2用量下,乳液法制备的聚苯胺/MoS2复合材料在0.8 A/g电流密度下的比电容为245 F/g,是溶液法聚苯胺/MoS2复合材料的3倍;充放电1000圈后的比电容保持率为82%,比溶液法聚苯胺/MoS2复合材料高11%,显示出更好的电容性能。

Capacitance Performance of Polyaniline/MoS2 Composites Prepared by Different Methods

Polyaniline/molybdenum disulfide composites were prepared in single-layer MoS2 suspension via solution polymerization and emulsion polymerization, respectively. The composites were characterized by FT-IR, and the electrochemical properties were determined by electrochemical workstation. The results show that PANI/MoS2 electrode prepared by emulsion polymerization has the better capacitance performance. The specific capacity was 245 F/g at the charge-discharge current density of 0.8 A/g, which are 3 times than that of solution polymerization. After 1000 charge-discharge cycles the retention ratio of specific capacity was 82 %, which are l 1% higher than that of solution polymerization.
