摘要
采用溶液聚合法,对涤纶织物进行表面改性,形成聚苯胺(PANI)-聚吡咯(PPy)共聚物改性的涤纶织物(PANI-PPy/涤纶织物),并将其作为超级电容器的电极材料,系统研究了苯胺和吡咯共聚时单体浓度的变化对PANI-PPy/涤纶织物的微观形貌、结晶性能、化学结构、电化学性能的影响。研究表明:PANI-PPy共聚物能在一定程度上提高涤纶织物的电化学性能,且当苯胺和吡咯的单体浓度比值为0.75∶0.25时,涤纶表面共聚物的比表面积最大;当电流密度为2 mA/cm^(2)时,PANI-PPy/涤纶织物的面积比电容达1 046.26 mF/cm^(2),此时改性织物的导电率和电化学性能达到最佳,是一种具有良好应用前景的超级电容器电极材料。
This paper prepared PANI-PPy/polyester fabric through surface modification on polyester fabric by using solution polymerization method, and the resultant fabric was used as the electrode material of supercapacitor. It systematically studied the influence law of monomer concentration change during copolymerization of aniline and pyrrole on the micro-morphology, crystallization, chemical structure and electrochemical properties of PANI-PPy/polyester fabric. The research shows that PANI-PPy copolymer can improve the electrochemical performance of the polymer fabric to some extent. When the monomer concentration ratio of aniline to pyrrole is 0.75∶0.25, the specific surface area of the copolymer on polyester surface reaches the largest. When the current density is 2 mA/cm^(2), the specific capacitance of PANI-PPy/polyester fabric is up to 1 046.26 mF/cm^(2), and at this time the conductivity and electrochemical performance of the modified fabric are the best. This study indicates the resultant fabric is a good electrode material for supercapacitor with good application prospect.
