Description
PAN molecule has strong polar nitrile groups.It is relatively insoluble in nature. PAN based carbon fibers possess very high strength compared to other polymeric precursors. When subjected to heat treatment, it can produce high carbon yield giving rise to thermally stable, highly oriented, graphite like molecular structure. Generating carbon-fiber from PAN based fiber is a combination of three processes-- namely stabilization, carbonization and graphitization.Polyacrylonitrile (PAN) is used as polymeric carbon precursor to form carbon fibers, electrospun activated carbon materials having meso-macro pores, carbon black additives.These are consecutively used in hydrogen storage, EMI shielding, electrochemistry, separation processes. It may find applications in PAN based single walled carbon nanotube composites.Specifications
