A simple magnetic stirring process to synthesize poly(diaminoanthraquinone)/ multi walled carbon nanotubes(PDAAQ/MWCNTs)composite using 1,4-diaminoanthraquinone(DAAQ)and multi-walled carbon nanotubes(MWCNTs)via π-π stacking was reported.The as prepared composite was investigated by Fourier transform infrared spectroscopy(FTIR),transmission electron microscopy(TEM),cyclic voltammetry(CV)and galvanostatic charge discharge(GCD).The results showed that a 3-4 nm thickness of PDAAQ was well coated on the outer surface of the MWCNT,which clearly indicated the formation of a multilayer of DAAQ molecules on the nanotube surface.This unique structure of PDAAQ/MWCNTs composite greatly increases the surface area of composite and the utilization of PDAAQ.Thus,the homogeneous PDAAQ/MWCNTs composite exhibits a high pseudocapacitance characteristic.
