聚吡咯/脲醛树脂多孔碳的超级电容性能
Supercapacitive performance of polypyrrole/urea-formaldehyde resin derived porous carbon
摘要
Abstract
Urea-formaldehyde resin(UF) derived porous carbon (UFC)was prepared by using UF as the precursor and activated with KOH solution.Polypyrrole(PPy)/UFC composite was further prepared by in-situ chemical polymerization.The nanocomposite was analyzed by SEM,XRD,Fourier-transform infraredspectra (FTIR).The electrochemical performance of the nanocomposite was tested by cyclic voltammetry,electrochemical impedance spectroscopy (EIS)and galvanostatic charge-discharge.The PPy/UFC composite had higher specific surface area and better electrochemical performance than single PPy and UFC.When cycled in-1.0 ~0 V with 4 A/g,its specific capacitance was 545 F/g,the capacitance retention rate was 91% after 2 000 cycles.关键词
