本論文研究開發具反應型親水性PU樹脂與奈米二氧化鈦粒子形成有機/無機混成樹脂系統，將混成親水性PU樹脂分別塗布於玻璃或織物表面，使玻璃表面產生具有長效型的防霧功能、或使疏水性織物表面具有耐水洗的親水性質。首先製備含異氰酸鹽(NCO)末端基的親水性(含聚乙二醇)PU預聚物；針對應用玻璃和織物兩種材質的親水處理，此常溫架橋型親水性有機/無機PU混成樹脂，分別使用不同末端反應型官能基的PU樹脂，如下: 玻璃防霧處理：首先將製備含NCO末端反應型官能基之PEG-1000之PU 預聚物，再加入3-氨丙基三乙氧基(3-aminopropyl)triethoxysilane(APTES) 與PU預聚物形成 silane末端基，使其能與玻璃表面SiOH產生Si-O-Si化學鍵結，再加入tetra-butyl titanate (TBT)，以溶膠-凝膠法(Sol-gel process)產生親水性奈米二氧化鈦粒子，增加親水效果，使玻璃達到長效型親水/防霧功能。 織物表面改質：首先將製備製備含NCO末端反應型官能基之PEG-1000之PU 預聚物，再加入二羥基乙基甲基丙烯酸酯(2-HEMA)與PU預聚物形成紫外光硬化型寡聚物，再加入tetrabutyl titanate (TBT)後，將其分散在水中。利用羧基與TMPTA-AZ進行Michael Addition的常溫架橋反應，將織物含浸塗佈，再經紫外光硬化處理乾燥後，親水性有機/無機混成UV-WPU樹脂在織物上形成互穿式網狀交聯(IPN)，嵌入織物纖維中，最後經AATCC-22標準水洗測試證明織物具長效型親水性及耐水洗的性質。 水性高分子油墨運用:首先利用AIBM作為起始劑，將GMA與AA反應形成含環氧官能基之高分子，再加入染料，使其與高分子鍵結，形成高分子水性油墨，並加入常溫架橋劑，形成耐水和耐溶劑的水性高分子油墨用途。 This research has been developed a series of hydrophilic PU resin materials for the treatments of anti-fogging glass and hydrophilic PET textile, respectively. Anti-fogging Glass: A PEG-1000 containing NCO-terminated PU prepolymer is prepared and it reacted further with 3-aminopropyl triethoxy-silane, APTES (consists silane and amino function group), and a silane-terminated PU oligomer is resulted after TBT (for nano-TiO2 via sol-gel process) is added at pH=5 for 65 oC/6 hr. A silane-terminated hydrophilic PU oligomer is applied on an anti-fogging glass. The glass anti-fog effect will stand for more than 10 minutes and also remain excellent adhesion (cross-cut passes 4 B) after dipping in boiling water for 10minutes or in alcohol for 1 hr . Hydrophilic Textile treatment: A mixture of nano-TiO2 (TBT via sol-gel process) and hydrophilic (PEG-1000) group-containing UV-curable aqueous PU resin(UV-WPU) has been prepared for breathable textile treatment. A PET textile has been treated with UV-WPU by dipping process and then cured by UV-radiation. A hydrophilic PET textile has resulted and that demonstrated by its water diffusion area and water absorption. And PET textile still is hydrophilic after 20 water washing cycles (AATCC method). Due to UV-curing process creates IPN (interpenetrating polymeric networks) of hydrophilic UV-WPU between textile fibers that enhancing water washing durability.
