Fabrication of carbon nanofiber-polyaniline composite flexible paper for supercapacitor

In this work we report a low cost technique, via simple rapid-mixture polymerization of aniline using an electrospun carbon nanofiber (CNF) paper as substrate, to fabricate free-standing, flexible CNF-PANI (PANI = polyaniline) composite paper. The morphology and microstructure of the obtained produc...

Description
Summary:In this work we report a low cost technique, via simple rapid-mixture polymerization of aniline using an electrospun carbon nanofiber (CNF) paper as substrate, to fabricate free-standing, flexible CNF-PANI (PANI = polyaniline) composite paper. The morphology and microstructure of the obtained products are characterized by FESEM, FTIR, Raman and XRD. As results, PANInanoparticles are homogeneously deposited on the surface of each CNF, forming a thin, light-weight and flexible composite paper. The resulting composite paper displays remarkably enhanced electrochemical capacitance compared with the CNF paper, making it attractive for high-performance flexible capacitors. A combination of electrospinning and rapid-mixture polymerization techniques has been successfully utilized to prepare freestanding and flexible CNF-PANI composite paper, which displays remarkably enhanced electrochemical capacitance compared with the pristine CNF paper.
