Electrochemical Preparation and Capacitance Characteristics of Conjugated Microporous Polymer

  • 摘要: 以聚集诱导发光(AIE)材料咔唑基三苯乙烯衍生物(TPCz)为单体,采用循环伏安法(CV)以聚集诱导发光(AIE)材料咔唑基三苯乙烯衍生物(TPCz)为单体,采用循环伏安法(CV)原位聚合制备了咔唑基三苯乙烯衍生物多孔聚合物薄膜(TPCz-CMP). 利用红外光谱(FT-IR)、紫外-可见吸收光谱(UV-vis)、高倍透射电镜(HR-TEM)等手段对其结构和形貌进行了表征,并对CMP薄膜修饰的电极进行了CV、恒电流充放电(CP)及交流阻抗(EIS)等电化学性能测试. 结果表明, TPCz-CMP薄膜具有微孔结构,在电流密度为4 A/g时,TPCz-CMP薄膜电极的比电容达到193 F/g,是一种具有优良应用前景的超级电容器材料.

     

    Abstract: 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.
