聚苯胺在碳纤维上的一维生长及电容性能研究
One dimensional growth of polyaniline and its pseudocapacitive property study
本文首先利用超声和电化学氧化等方法对碳纤维布（CFC）进行预处理，制备亲水性和电化学特性良好的碳纤维（ANEA）。再分别利用过硫酸铵（APS）和K2Cr2O7引发苯胺聚合，在碳纤维表面覆盖聚苯胺（PANI），制备ANEA-PANI-APS和ANEA-PANI-K2Cr2O7。利用扫描电镜（SEM）观测了PANI的表面形貌，利用红外光谱（FT-IR）研究了其振动吸收，利用循环伏安（CV）扫描和恒电流充放电（CP）实验研究了其超电容性能。研究发现，ANEA-PANI-APS上的PANI以纳米纤维形式存在，有助于聚合物与电解液充分接触而提高其电化学性能，其比电容可达644 F/g。
Polymerization of aniline was conducted through initiation by ammonium persulfate (APS) and K2Cr2O7, respectively on ultrasonic and electrochemical pretreated carbon fiber cloth ANEA to afford ANEA-PANI-APS and ANEA-PANI-K2Cr2O7. The morphologies of the polymers were investigated by scannining electron microscope (SEM). Their vibrations were studied by fourier transform infrared spectroscopy (FT-IR). Pseudocapacitive properties of the products were studied by cyclic voltammetry (CV) and galvanostatic charge/discharge (CP) experiments. It was found that one dimensional growth of PANI was controlled through APS initiated polymerization to afford nanofibrous polymer in ANEA-PANI-APS, which enables effect contact of the polymer with electrolyte to ensure its improved electrochemical properties. ANEA-PANI-APS displayed a high specific capacitance of 644 F/g.
