A simple one-step method was used for preparing the beta-cyclodextrin/polyacrylonitrile (PAN) nanofibers deposited with silver nanoparticles by electrospinning and followed by the reduction of the Ag+ ions. The nano-composite fibers were stabilized at 280 degrees C in air and activated at 800 degrees C for 1 h in steam/N2. The structures of nano-composite fibers were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), fourier-transform infrared (FTIR) spectroscopy, and X-ray diffraction analysis (XRD). The electrochemical behaviors of the composite of carbon nano-fibers were investigated by cyclic voltammetry and charge/discharge tests.
采用一种简单的一步法，通过静电纺丝制备负载银纳米颗粒的β-环糊精/聚丙烯腈（PAN）纳米纤维，随后还原Ag+离子。将纳米复合纤维在空气中280℃下进行稳定化处理，并在蒸汽/N2中800℃下活化1小时。通过扫描电子显微镜（SEM）、透射电子显微镜（TEM）、傅里叶变换红外（FTIR）光谱和X射线衍射分析（XRD）对纳米复合纤维的结构进行表征。通过循环伏安法和充/放电测试研究了碳纳米纤维复合材料的电化学行为。
