Electrochemical Preparation and Capacitance Characteristics of Conjugated Microporous Polymer

Conjugated microporous polymer deposited electrochemically from Carbazolyl Triphenyl Ethylene Derivative(TPCz-CMP) was prepared via in-situ polymerization by cyclic voltammetry(CV) with aggregation-induced emission(AIE) material (TPCz) as monomer. The structure and morphology of TPCz-CMP films were characterized by fourier transform infrared (FT-IR), ultraviolet visible spectrum(UV-vis), high resolution transmission electron microscope (HR-TEM)and other techniques. The electrochemical properties of electrode prepared by electrochemical polymerization which was consisted of TPCz-CMP were investigated by CV, galvanostatic charge-discharge (CP) and electrochemical impedance spectroscopy (EIS). The results suggest that TPCz-CMP films exhibit good microporosity and demonstrated a specific capacitance value as high as 193 F/g at current density of 4 A/g. TPCz-CMP turns out to be a prospect materials for supercapacitor.
