Abstract

The mixture of polyaniline (PANi) and PANi grafted multi-walled carbon nanotube (PANi-g-MWNT) was prepared by two step reaction sequences. MWNT was first functionalized with 4-aminobenzoic acid via “direct” Firedel-Crafts acylation in polyphosphoric acid (PPA)/phosphorous pentoxide (P2O5) medium to afford aminobenzoyl-functionalized MWNT (AF-MWNT). Then, aniline was polymerized via in-situ static interfacial polymerization in H2O/CH2Cl2 in the presence of AF-MWNT in organic phase to yield the mixture of PANi and PANi-g-MWNT. The mixture was characterized with a various analytical techniques such as Fourier transform infrared spectroscopy (FT-IR), wide angle x-ray diffraction (WAXD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), cyclic voltammogram (CV). Even after dedoping, the mixture displayed semimetallic conductivity (4.9 S/cm). The capacitance of the mixture was also greatly enhanced and its capacitance decay with respect to cycle times was significantly reduced.
