Characterization of carbon/carbon composites containing cellulose by electrospinning

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.
