Porous carbon materials have attracted much attention because of their versatile applications. In this study, carbon aerogel/polymer nanocomposites were developed to improve the electrochemical performance of supercapacitor. RF aerogels were synthesized via the sol-gel polycondensation of resorcinol(R) with formaldehyde(F) in a slightly basic aqueous solution. Carbon aerogels were obtained by pyrolyzing the RF aerogels at 1173K. Carbon nanocomposites were prepared by electrospinning of polyacrylonitrile(PAN) and poly(methyl methacrylate)(PMMA) solution with carbon aerogel in N,N-dimethylformamide(DMF). PMMA was used as supporting materials which keeps pores of aerogel, PMMA phase disappeared after thermal treatment. The morphology of carbon composites were investigated using SEM. The surface area and pore size were measured by BET. Also, electrochemical property of carbon aerogel/polymer composites were investigated by three electrode system. |
