Abstract
Designing and control of structure and nanotexture of carbon materials are important factors to designing and control of their functions. Here, firstly a brief explanation of structure and nanotexture of carbon materials was presented and then the destruction of nanotexture was shown to open some new functions and applications of carbon materials by focusing "exfoliation"; exfoliated graphite had high sorption capacity for heavy oils and exfoliated carbon fibers gave high capacitance of electrochemical capacitors.
