摘　　要：利用电化学法在不锈钢网上直接生长出了墨绿色、高比电容、光敏性的双功能聚苯胺薄膜,从而完全省略了加大电阻的黏结剂。采用紫外吸收光谱、扫描电子显微镜(scanning electron microscope,SEM)、循环伏安法(cyclic voltammetry,CV)、恒电流充放电(galvanostatic charge/discharge,GCD)及阻抗分析法(electrical impedance spectroscopy,EIS)等方法对样品进行表征和测试,并且在不同的测试条件下对电容进行了统计和比较。在3种网状结构的聚苯胺中,最疏松的聚苯胺网络具有最大的比电容(443.7F/g)和最高的导电性(44S/cm)。这是由于疏松的网状结构材料可以充分地与电解液接触,提高了聚苯胺薄膜的比电容。同时,该聚苯胺薄膜具有很好的光敏性质,对白光有最强的光电响应,可以作为光敏传感器。This paper reports the direct growth of ink green,high specific capacitance,photosensitive double-functional polyaniline film on stainless steel network by electrochemical method,thus the adhesive is completely omitted for decreasing resistance.The polyaniline samples were characterized and tested by ultraviolet absorption spectroscopy,scanning electron microscope(SEM),cyclic voltammetry(CV),galvanostatic charge/discharge(GCD)and electrical impedance spectroscopy(EIS).The comparison of capacitance was carried out under different test conditions.Among the three kinds of polyaniline with network structure,the most porous polyaniline network has the largest specific capacitance(443.7 F/g)and high conductivity(44 S/cm)because the loose network structure material can fully contact with the electrolyte which improves the specific capacitance of the polyaniline film.The polyaniline film also has good photosensitive properties with the strongest photoelectric sensitive to white light,which can be used as a photosensitive sensor device.
