摘要: Abstract Due to the advantages of material abundance and synthetic simplicity, polyaniline can be used as a high capacity cathode material. However, its practical application in battery has been hindered by poor electrochemical utilization cycling instability. To solve these problems, we synthesized Polyaniline-co-o-nitroaniline aniline. The copolymers were for 1:1 1:4 M ratios aniline o-nitroaniline acidic medium using ammonium persulfate oxidant their properties compared with that polyaniline. prepared samples have characterized number techniques including Raman spectroscopy, FTIR, UV–vis, conductivity. polymers showed less electrical conductivity than Unlike polyaniline, presence nitro group caused higher frequency dependence FTIR bands at 1560, 1306 1148 cm −1 are corresponding salt. band observed range 1100–1140 cm is characteristic conductive due charge delocalization on polymer backbone.
