Electrochemical preparation and analysis of organic composites

Abstract

Using different concentrations of aniline (PA) and γ-Fe2O3, by electrocatalytic polymerization method to form composite materials, which can be used in the development of supercapacitor electrode materials. And the composite products were tested to find the best ratio and compare properties of the composites with those of polyaniline. In this experiment, the concentration gradient method was used to design the concentration ratio of aniline (PA) and γ-Fe2O3 (1:1, 1:2, 1:4, 1:8, 1:16, 1: 32), and different concentrations of aniline (PA) (50 mM PA was diluted to 50mL with 0.01M, 0.1M and 1M sulfuric acid, respectively), and glassy carbon and uniaxial conductive glass (ITO) were used as working electrodes for comparative experiments, and the synthesis of electrode materials and performance analysis was carried out by cyclic voltammetry. The results show that the ratio of different concentrations has a great impact on the yield and performance of the product. According to the experimental results, in different variables, ITO glass as the working electrode, aniline (PA) diluted with 1M concentrated sulfuric acid, and PA and γ-Fe2O3 concentration ratio of 4:1 when the synthesis of combined efficiency is the best. The properties of the synthesized compound are much better than those of polyaniline
