    Abstract: 超斥水合成物及其超斥水的應用已被大量研究及使用,但基於許多超斥水合成物含有氟或將超斥水合成物塗佈於各種基材表面時,該超斥水合成物塗層由於被磨擦或沖刷,會失去超斥水的特性,基於超斥水合成物塗層的無毒與可靠度,本研究將含有高壓容器容積比例為70%之二乙烯苯單體、乙酸乙酯溶劑及偶氮二異丁腈起始劑之A混合溶液,進行高壓溶劑熱法已成功製備無毒且具有超斥水之聚二乙烯苯(PDVB)合成物,壓製成PDVB超斥水薄片時,其靜態接觸角與滑動角分別約為163°及1°。將已去木質素的木粉與含有高壓容器容積比例為70%之A混合溶液,經高壓溶劑熱法已成功製備具有超斥水之木粉,將超斥水木粉壓製成片後製成靜態接觸角與滑動角分別約為148°與2°的超斥水木粉薄片。為了增加超斥水合成物塗層的可靠度及其應用,使用環氧樹脂將該超斥水木粉薄片黏接於S25C碳鋼與6061鋁合金形成具有超斥水的複合工件。實驗結果顯示超斥水木粉薄片/環氧樹脂/S25C鐵片複合工件經過耐酸(1M之鹽酸水溶液)鹼(pH13.9之氫氧化鈉)試驗後,該複合工件的靜態接觸角與滑動角約為153°與2°以下。使用6kPa固定負荷的菜瓜布磨擦該複合工件後,該複合工件的靜態接觸角與滑動角約為146°與2°以下。使用含有1wt%細砂(平均粒徑約為300um)之純水沖刷超斥水木粉薄片(內壁)/環氧樹脂/6061鋁管複合工件後,超斥水木粉薄片之靜態接觸角與滑動角略降分別約為140°與18°。另外,將開孔超斥水木粉薄片用螺栓鎖定於兩個中空壓克力管的法蘭後,成功設計一款可有效及快速分離液體中含有氣體之水氣分離模組。
    The superhydrophobic material and superhydrophobic application has been widely applied and extensively studied. Some superhydrophobic materials have toxic compounds such as fluoride or these are prone to lose the superhydrophobicity when they are being abraded or eroded. In the present study has successfully made a superhydrophobic coating with non-toxic and long-lasting durability. Firstly, we prepared a non-toxic polydivinylbenzene (PDVB) plates under high pressure solvothermal method with solution A – i.e., mixed solutions of divinylbenzene monomer, ethyl acetate solvent and azobisisobutyronitrile initiator in 70% volume ratio of high pressure vessel. The experimental results showed that the PDVB plate is approximately 163° contact angle and the sliding angle (SA) is about 1°. Additionally, the present experiment using delignined wood powder with similar parameters as above to form a superhydrophbic wood powder plate and produced CA and SA approximately 148° and 2°. In order to improve the durability and application, the superhydrophobic wood powder plate was adhered to S25C carbon steel and 6061 aluminum alloy pipe with epoxy resin to form a superhydrophobic composite workpieces. The experimental results show that the CA and SA is 153° and 2°,respectively during the test of the alkali (pH 13.9 sodium hydroxide)and the acid (1M aqueous solution of HCl) treatment. Additional, the 6kPa fixed load of melon cloth was exerted on the composite workpieces with CA and SA is 146° and 2°. Liquid erosion is using water containing 1wt% fine sand (the average particle size is 300μm) with numbers of CA 140° and SA 18°. In addition, we successfully designed a module that can effectively and quickly separate the gas from the liquid. It is prepared by fixed the openings superhydrophobic wood powder plate between the two flanges of acrylic tube with bolt.
