  表面自由能和中子反射率评价聚甲基丙烯酸酯侧链五氟硫烷基的疏水性

  摘要：

  表面保护、防污、粘附和其他应用需要疏水表面或涂层。为了实现疏水性能，通常采用氟基涂层，例如引入三氟甲基或二氟亚甲基。合成化学的最新发展表明其他有机氟烷基基团适用于实现更疏水的表面。在这项研究中，我们专注于五氟硫烷基 (-SF 5 ) 基团的疏水特性。我们合成了具有-SF 5基团或其他官能团（-CF 3，-CH 3, 和-H) 在它们的侧链中，并基于水和乙二醇的接触角以及它们的薄膜对水的亲和力通过中子反射率测量来评估它们的疏水性，以证明-SF 5基团的优越疏水性。具有-SF 5基团的聚甲基丙烯酸酯薄膜的水接触角较大，这表明表面自由能低于其他具有-CF 3、-CH 3和-H侧链的聚甲基丙烯酸酯薄膜的表面自由能。此外，对与空气和水接触的聚合物薄膜的中子反射率分布的拟合分析表明，水与具有-SF 的聚甲基丙烯酸酯薄膜表面之间的亲和力最低。合成聚合物的薄膜中有5组。因此，我们证明了五氟硫烷基作为高级疏水基团的潜力。
