| 摘 要： | 采用化学气相聚合法制备了聚3,4-乙烯二氧噻吩(PEDOT))/纳米银复合薄膜,研究了复合纳米薄膜的导电及电化学性能。研究结果表明,PEDOT/纳米银复合薄膜的电导率为54.8 S/cm,高于纯PEDOT薄膜的电导率(17.3 S/cm),复合纳米薄膜的比容量为174.5 F/g,明显高于纯PEDOT薄膜的比容量。循环测试1000次后,复合膜的比容量保持率为81.6%,具有良好的电化学稳定性。这种化学气相聚合制备的聚合物复合纳米薄膜在超级电容器及导电材料领域有着良好的应用前景。

| Abstract: | A chemical vapor-phase polymerization (VPP) method was employed to prepare poly-3,4-ethylenedioxythiophene/nano silver nanocomposites. The electrical and electrochemical performance of the nanocomposites was investigated. The conductive results show that PEDOT/nano silver exhibits conductivity ca. 54.8 S/cm, which is higher than pure PEDOT films (17.3 S/cm). This PEDOT/nano silver composites exhibits higher specific capacitance (ca. 174.5 F/g) than pure PEDOT due to the high specific surface area of nano silver. The cycle performance reveals that the nanocomposites keep 81.6% initial capacitance after 1000 cycles, indicating excellent cycling stability. This VPP PEDOT nanocomposites show promising application in supercapacitor and conducting materials. |
