We have succeeded in synthesizing metal folding ceramic (SiC) nano-fiber from Si-based precursor polymers using Single Particle Nanofabrication Technique (SPNT). Si-based polymers were cross-linked along ion tracks of nano-size in diameter through the whole thickness of polymer thin film. Nano-fiber was developed on the surface of the substrate by dissolution and washing away of uncross-linked polymer by solvent. Subsequent pyrolysis converted polymeric into inorganic SiC nano fibers. The diameter of nano fiber was depended on LET (liner energy transfer), molecular weight and cross-linking efficiency of polymers.
