Preparation of porous polyaniline withtemplate method and its electrochemical properties

Abstract

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
