摘要
聚苯胺(PANI)是一种比电容很高的电容材料,但由于其容易团聚导致实际利用率不高。目前提高PANI利用率的方法主要有制备大分子掺杂PANI或构筑PANI纳米阵列结构等。文中采用化学聚合法构筑了Nafion掺杂聚苯胺纳米阵列电容材料,在苯胺浓度为10 mmol/L时所制备的复合材料PANI/Nafion-10性能最佳。PANI/Nafion-10在2 A/g的电流密度时表现出1024 F/g的比电容,纯PANI(PANI-10)比电容仅为714 F/g。
Polyaniline(PANI)is a kind of capacitive material with high specific capacitance,but it is easy to agglomerate,resulting in low actual utilization.At present,the main methods to improve the utilization of PANI are preparing macromolecular doped PANI or constructing PANI nanoarray structures.In this paper,Nafion-doped polyaniline nanoarray capacitor material was constructed by chemical polymerization method.When the aniline concentration is 10 mmol/L,the composite material(PANI/Nafion-10)has the best performance.PANI/Nafion-10 exhibits a specific capacitance of 1024 F/g at a current density of 2 A/g,while pure PANI(PANI-10)exhibits a specific capacitance of only 714 F/g.
