摘要

A Cabbage like polyaniline@hydroquinone composite microsphere was synthesized using in situ polymerization and the electrochemical performance was investigated. The core template, p-benzoquinone, is demonstrated working as an oxidizing agent for the in situ polymerization of PANI, and to be reduced to 1, 4-hydroquinone after reaction. The morphology and microstructure of samples were examined by field emission scanning electron microscopy, transmission electron microscope, X-ray photoelectron spectrometer, thermo gravimetric, and Fourier transform infrared spectra. The cyclic voltammetry, impedance and galvanostatic charge/discharge analysis demonstrates that PANI contributes electronic conductive channels for hydroquinone, and hydroquinone works as a pseudocapacitance component. The prepared PANI@hydroquinone nanocomposite exhibits brilliant electrochemical properties of a specific capacitance of 126.0 F g(-1) at a scan rate of 5 mV s(-1) and enhanced stability of about 85.1% of initial capacitance retained after 500 cycles scanning at a current density of 1 A g(-1).
