플라즈마를 이용한 유기 실리콘 박막의 합성과 그 특성에 관한 연구

A study on the formation and properties of silicone thin film by the plasma polymerization.

In the study, samples were made on the electrode in internal glass bell jar by the radio frequency discharge polymerization. The polymerization rate of samples was observed as a function of r.f. discharge power. The characteristics of polymers obtained from TMDSO and HMDSO were analyzed by FT-IR and TGA, and their electrical properties were examined on insulation resistivity, breakdown voltage, dielectric constant, and tan ${\delta}$. (1) There was no difference between PPTMDSO and PPHMDSO in a polymerization rate and thermal and electrical properties. (2) The growing rates of thin film with discharge powers were from $0.42{\mu}/h$ to $1.2{\mu}m/h$. (3) According to IR spectra analysis, discharge power did not effect polymer structure due to polyermization mechanism and effected only polymerization rate. (4) PPTMDSO and PPHMDSO were thermally resistive polymers which did not decompose to $300^{\circ}C$.
