【摘要】 <正>表面浸润性是物质的一个主要的物理化学性质,在催化、采油、选矿、润滑、涂饰、防水、生物相容等领域有着重要的应用。固体表面的浸润性是由表面化学组成和表面微观结构两方面因素决定。一般地,液体对固体的浸润程度以接触角θ表示,而既有大的接触角和又有小的滚动角的表面被称之为超疏水表面。超疏水表面具有强疏水、自清洁、减阻等性能, 在建筑外墙涂料、减阻防污涂层及人体植入材料表面涂层等方面具有重要的潜在应用。更多还原

【Abstract】 Polymer was dissolved in various solvents to form molecular solution or micellar solutions due to the different solvent quality. The resulting solutions were cast on clean glass slice and dried under ambient temperature. SEM images show that the as-prepared coatings exhibit different surface morphologies and water contact angle measurements indicate these coatings possess different hydrophobicity ranging from moderate to super-hydrophobicity. The different chain motion ability of the two blocks in different solvents contributes to the appearance of such phenomena.更多还原
