摘要/Abstract

摘要： 通过以极慢的速率滴加氧化剂水溶液方式,构建了受限的油水反应界面,在无模板条件下制备了多孔聚苯胺,并研究了产物的结构和用作超级电容器电极材料的电化学性能.结果表明:产物为银耳状多孔结构,富含小于10 nm的中介孔.在电流密度为1 A/g时,充放电时间近似对称,比电容高达441 F/g,经2 000次充放电循环后,比电容损失率为27.3%,该聚苯胺表现出良好的电化学性能.

Abstract: The limited oil-water reaction interface was constructed by an adding oxidant water solution approach at a very slow rate, porous polyaniline was prepared without template, and the structure and the electrochemical properties using as the electrode material of supercapacitor were studied. The results showed that the product presented porous structure looking like a tremella. The distribution of pore diameter was mainly in range of less than 10 nm. The charge and discharge time was approximately symmetric and the specific capacitance was 441.6 F/g when the discharge current was 1 A/g. The loss rate of the capacitance was 27.3% after 2 000 of galvanostatic charge discharge (1 A/g). Polyaniline showed good electrochemical properties.

Key words: poylaniline, interfacial polymerization, electrochemical properties
