Title Synthesis and electrochemical performance of Ployaniline hybridization composite
Abstract
The composite material is a hotspot of high performance supercapacitor electrode materials research, which compounded by Nitrogen-doped porous carbon (NMC) as matrix and polyaniline (PANI)。 In this paper, the research mainly involves two aspects: the composite microstructure and electrochemical properties is influenced by which different concentrations of metal ions Ni2+ and Co2+ were added ,respectively, with acid co-doped NMC@PANI; Using MnSO4 and APS, the ternary composite of nitrogen-doped porous carbon @MnO2@PANI was synthesized through the ultrasonic dispersion method and chemical in-situ polymerization, then studying its morphology and electrochemical properties。 The composite structure were investigated by FTIR、XRD、Raman、SEM and other methods, and electrochemical capacitivetests were analyzed by electrochemical workstation。
