As an effort to prepare carbon nanosheet and carbon film through catalyst- and transfer free process, several research groups have reported carbonization of polymers and small molecules such as polyacrylonitrile (PAN) and a small molecular pitch extracted from petroleum. Carbon nanosheets converted from PAN or pitch were obtained through two steps: cyclization and carbonization. Because the quality of the carbon materials sensitively depends on the cyclization conditions such as temperature, ramping rate, and oxygen contents, there is a great need for a cyclization-free process. Recently, we developed a cyclization-free carbonization process using PIM-1 (polymer of intrinsic microporosity). In this presentation, shape and dimension control of carbon materials and direct use as electrodes of organic solar cells or supercapacitors will be discussed.
