    Abstract: 本研究利用具有低表面能的聚矽氧烷( PDMS )與異氟爾酮二異氰酸脂 ( isophorone diisocyanate )合成具有NCO末端官能基含聚矽氧烷聚胺脂預聚物,再加入二羥基乙基甲基丙烯酸酯( 2-hydroxyethyl methacrylate ),形成含壓克力紫外光硬化型聚胺脂樹脂。在樹脂中加入具有低表面能的長鏈壓克力樹脂提升樹脂的撥水效果。再利用溶膠凝膠法( Sol-gel process )摻入四乙氧基矽烷( TEOS )合成氧化矽粒子,並用3-(三甲氧基甲硅烷基)丙基-2-甲基-2-丙烯酸酯( TESPMA )修飾氧化矽粒子表面官能基乾燥處理後,產生氧化矽粒子和聚胺脂樹脂進行混摻再將混摻後的樹脂塗佈於材料表面增加材料表面粗糙度,最後利用紫外光照射塗佈表面樹脂產生交聯反應,增加耐水壓特性,因為樹脂中聚矽氧烷的微相轉移,造成塗佈材料表面的表面能降低,增加撥水效果。.
    在織物的撥水處理:首先將聚酯織物( PET )浸泡鹼液精煉,再將聚胺脂預聚物添加光起始劑(紫外光硬化型)/過氧化物(熱硬化型),將聚胺脂樹脂以含浸方式塗佈在織物上後,烘乾後再經紫外光硬化/加熱硬化,最後經美國紡織化學協會( AATCC )標準測試其撥水效果及耐水洗性質。
    A low surface energy and hydrophobic material, Polydimethylsiloxane (PDMS) has been selected to react with isophorone diisocyanate (IPDI) and forming a NCO-terminated PDMS-containing Polyurethane (PU) prepolymer, it then reacts further with 2-hydroxyethyl methacrylate (HEMA) and results in a formation of acrylate-terminated PDMS-containing PU oligomer. It is compounded with hydrophobic long-chain hydrocarbon (its carbon number more than 16 and that is similar to wax) acrylate (monomer) and becomes UV-curable hydrophobic PU coating material. Nano-particles are generated from a sol-gel process by mixing tetra-ethyl siloxane (TEOS) and 3-(trimethyyloxysilyl)propyl methacrylate (TESPMA) that creates even rough surface and that increases water-resistance on the coated hydrophobic textile surface after UV-curing process.

    Hydrophobic textile treatment: A refined PET textile (treated with diluted NaOH solution and cleaned with de-ionized water) is treated with UV-curable hydrophobic PU oligomers and cured with UV-radiation or heating. The results of hydrophobic treated textiles are evaluated by AATCC testing methods.
