碩士 === 龍華科技大學 === 化工與材料工程系碩士班 === 106 === The products of biomedical materials pay attention to safety, reliability and effectiveness. In order to improve the defect of biomedical materials in organisms, such as catheter thrombosis, cell adhesion, infection of implants, etc., In this study, A hydrophobic film was prepared by using （Hexamethyldisilazane, HMDSN） as precursor by Atmospheric Pressure Plasma Jet and a sol-gel method, and the drophobic film was applied to silicone rubber. The suitability of materials as medical materials. The experimental results indicate that the surface properties of the Atmospheric Pressure Plasma Jet coating at different intervals are different. Adding SBMA monomer between the film and the substrate increases the adhesion of the film, which not only improves the contact angle, but also increases the durability of the film. The best experimental parameters of the slurry membrane system are SBMA monomer with a spacing of 20mm. The SiOx film prepared by another traditional process Sol-Gel method is coated on the test piece and found to have hydrophobic effect and maximum contact angle. up to 146.3° and 148.9°.Observing the change of surface morphology, it is found that the particle size of SiOx in the two processes is 70-100 nm. However, it is known from the analysis of the material structure that the SiOx crystallinity of atmospheric plasma is superior to that of Sol-Gel method, and the film is excellent. The state in a high temperature environment is also more stable than the Sol-Gel film.
