제목 SiC inorganic 3D microstructures of near zero-shrinkage fabricated by Pt catalyst using stereolithography
초록 To the best of our knowledge for the first time, we have described a novel method to fabricate microstructures of inorganic preceramic polymers by two-photon 3D microfabrication method via photohydrosilylation. Pt catalyst was employed insted instead of a two-photon absorption(TPA) initiator for photohydrosilylation. The liquid precursor polymer was loaded with 1wt% of TPA initiator and was photocuried. After two-photon crosslinking process, inorganic preceramic polymers followed by high pyrolytic temperature (600°C) in a nitrogen gas atmosphere such as peroxide compounds. SiC structures Extremely low shrinkage (4%) was observed during the experiments.
