Two-photon 3D Microfabrication of Inorganic Preceramic Polymers Using Photohydrosilylation Catalysts |
| 초록 |
Fabrication of three-dimensional polymeric structures by two-photon initiated chemistry take advantage of the spacial selectivity of two-photon absorption(TPA). 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. (η5-cyclopentadienyl) Trialkylplatinum was employed as a two-photon absorption(TPA) initiator for photohydrosilylation of commercially available inorganic preceramic polymers. The liquid precursor polymer was loaded with 1wt% of TPA initiator and was photocuried using 200mw laser power for few ms exposure time. After two-photon crosslinking process, inorganic preceramic polymers followed by high pyrolytic temperature (600oC) in a nitrogen gas atmosphere such as peroxide compounds. SiC structures. Extremely low shrinkage (4%) was observed during the experiments. |
