Abstract

Carbon nanofibers contained nano cellulose were prepared and the resulting carbon nanofiber composites were characterized by electron microscopy, Brunauer-Emmett-Teller (BET) method and image analysis. The samples are also evaluated as electrodes of electric double layer capacitor. The diameters of nano fibers are around 300nm estimated by scanning electron microscope (SEM). Structure of the nano fibers is revealed by transmission electron microscope (TEM) observation and image analysis. The nano structured carbons are porous materials with large specific surface area. The nano and micro pores are seemed to be formed by intertwining of heterogeneous catenulate molecular of cellulose and PAN (poly acrylonitrile) or PVA (polyvinyl alcohol) each other and/or missing of the cellulose during carbonization.

静电纺丝法表征含纤维素的碳/碳复合材料

制备了含纳米纤维素的纳米碳纤维，并用电子显微镜、BET法和图像分析对纳米碳纤维复合材料进行了表征。并对样品作为双电层电容器的电极进行了评价。通过扫描电子显微镜(SEM)估计纳米纤维的直径约为300nm。通过透射电子显微镜(TEM)观察和图像分析揭示了纳米纤维的结构。纳米结构碳是具有大比表面积的多孔材料。纳米孔和微孔似乎是纤维素与聚丙烯腈或聚乙烯醇的非均相链状分子相互缠绕或碳化过程中纤维素的缺失而形成的。
