| Summary: | 碩士 === 國立中央大學 === 光電科學與工程學系 === 107 === In recent years, with the development of smart automotive electronics, the use of plastic as a substrate for automotive display has a unique product value of low cost, good optical properties, and corrosion resistance. However, compared with glass, the adhesion for plastic between the substrate and the film is worst due to it low surface energy. Moreover, it is easily absorb some water contents on its surface, causing the out-gassing during the deposition process.
In order to solve the above problem of plastic coating, the study performs a baking treatment for plastic substrate before thin film deposition, and establishes an experimental method for removing the water contents in a short time. The surface of the plastic is modified by an ion source to increase the number of surface functional groups, greatly improve the adhesion of the substrate surface to the film. The functional groups are measured by FTIR. We also deposited an oxygen-deficient thin film as an interlayer between substrate and anti-reflective(AR) coating.
Finally, the plastic substrate treated by baking, surface activation, and adhesion layer deposition can pass the high temperature/humidity environmental test for 1000 hours without thin films peeling.
