Synthesis of Photosensitive Preceramic Silazane Oligomers for Photopatterning |
초록 |
Oligomeric vinylsilazanes (OVSiN) are commonly used for the fabrication of non-xoide ceramic structures usually by heat curing and then pyrolysis. In order to synthesize photocurable OVSiN for curing at room temperature, photosensitive acrylate groups were introduced to the backbone through a reaction between NH of OVSiN and isocyanate of 1,1-bis(acryloyloxyethyl)ethyl isocyanate and the reaction was characterized by 1H-NMR and IR spectra. The photosensitivity of the acrylated OVSiN was investigated by DPC, UV absorption, and IR spectroscopy. The acrylated OVSiN formulations mixed with 5 wt% of a photoinitiator were found to be cured within 30 sec by UV irradiation with about 10 mwatt/cm2 at 365nm. The fabrication of ceramic patterns using the acrylated OVSiN was also discussed. |
