中文摘要：

以无纺布（NW）为柔性基底,通过化学镀镍法在NW的纤维表面沉积镍制得柔性导电基底（Ni/NW）。然后以吸附有FeCl3·6H2O的Ni/NW与吡咯蒸气进行反应,通过原位氧化法制备了PPy/Ni/NW柔性复合电极材料并优化了制备条件。用X射线衍射（XRD）、X射线光电子能谱（XPS）和扫描电子显微镜（SEM）对复合材料的结构形貌进行表征。以聚乙烯醇/磷酸为凝胶电解质,PPy/Ni/NW为电极组装了柔性固体电容器。用循环伏安、恒电流充放电和电化学交流阻抗法研究了复合材料的电化学电容性能。研究发现在2mV/s时,柔性固体超级电容器的面积比电容可达150mF/cm^2,并且在弯曲状态下其比电容与没弯曲时相比没有明显差别,说明电容器具有可弯曲性。

英文摘要：

The flexible conductive substrate based on polyester nonwoven fabric （NW） are fabricated by coating Ni layer on NW through electroless plating. The polypyrrole is deposited on the substrate of Ni/ NW through chemical oxidation polymerization by using FeCl3 · 6H2O adsorbed on Ni/NW as oxidatant, and the concentration of FeCl3· 6H2O is also optimized in order to get the optimal composites. The obtained composites are characterized by using X-Ray diffractomer, X-ray photoelectron spectroscopy and scanning electron microscope and the properties of the capacitor cells assembled by the composites are investigated by cyclic voltammetry, galvanostatic charge/discharge and electrochemical impedance spectroscopy measurements. The results show that the specific capacitance of the optimal flexible solid capacitors assembled by optimal composites can reach to 150 mF/cm^2 at scan rate of 2 mV/s and that the capacitive properties of the capacitor in bent state can almost remain unchanged compared with its normal state.
