近年來在親水塗層研究中，有一種表面具極端濕潤行為而被積極研究，即為超親水表面。當水滴滴附於超親水表面時，其水接觸角將小於10o，有助於使液體快速攤平，達到快速乾燥的優異性、除霧等特性。 本研究所製備之超親水聚合膜，先行使用電漿蝕刻聚碳酸酯表面，使其表面具有粗糙度，再利用有機矽烷做為單體進行電漿聚合反應，使親水自由基沉積於基板上。藉由調變蝕刻參數，如電漿電流、電壓與鍍製時間等，使表面極為粗糙且越粗糙之表面其上所含超親水官能基越多，可提升超親水持久性。在製備過程，使用光放射光譜儀作為即時監控電漿解離之情況，使單體擁有較高裂解出親水自由基的機率。經X射線光電子能譜儀分析超親水聚合膜之組成元素含量，其親水官能基具有最多含量，因此讓水接觸角小於10o，達到超親水效果。 在持久性方面，射出型聚碳酸酯基板之超親水持久性可達34天，而押出型聚碳酸酯基板可達39天。;In recent years, there is a kind of extreme wetting behavior on the surface of hydrophilic coating, which is the super hydrophilic surface. When the water droplets are attached to a super-hydrophilic surface, the water contact angle will be less than 10 degrees. It is helpful to make the water droplets spread quickly and achieve the excellent properties of fast drying and mist removal. The aim of this study is to characterize the Super-Hydrophilic Polymer Films on Polycarbonate Substrate. First using oxygen and argon plasma to etch surface with roughness, and then using organic silane as the monomer for plasma polymerization .Finally hydrophilic free radicals deposited on the substrate. By adjusting the etching parameters, such as plasma current, voltage and deposition time, etc., making the surface extremely rough. The more rough the surface, the more hydrophilic functional on the surface, which can promote the persistence of super hydrophilic. In the preparation process, using optical emission spectrometer as a real-time monitoring of the plasma dissociation, so that the monomer has a higher probability of polymerize hydrophilic free radicals. The content of the constituent elements of the plasma polymerization film is analyzed by XPS, the hydrophilic functional has the most content, so the water contact angle is less than 10 degrees and achieves the super hydrophilic effect. In terms of durability, the super hydrophilic durability of the injection molded PC substrate can be up to 34 days. The compression molding PC substrate can be up to 39 days.
