摘要:
通过简单的涂覆方法,结合宏观粗糙的表面和处理的低表面能材料制备超疏水钢薄片.海水的接触角高达130.16o,新的卡西-巴克斯特方程从理论上预测了这种新型材料的接触角,得到的预测 结果与实验吻合.表征了超疏水钢网小船的装载能力.最大载重约为17.50 g,这种微型钢网小船经过含量为2%的三甲氧基硅烷溶液处理.小船优异的负载能力可能归因于钢丝网表面的空气膜的作用.

Abstract:
A superhydrophobic steel mesh film was prepared by combination of macro-scale rough sur-face and low surface energy material treatment through a facile coating method. The contact angle for seawater is measured to be as high as 130.16o. A reformed Cassie-Baxter equation was applied for the theoretical predictions of this novel material for the first time. Good agreement between the predictions and experiments was obtained. The loading capacities of these boats, fabricated from the resulting hydrophobic steel meshes, were also character-ized. The highest loading weight about 17.50 g was obtained by the steel mesh treated by 2.0wt% (heptadecafluoro-1,1,2,2,-tetradecyl)trimethoxysilane solution. The striking loading capacity of this miniature boat may be attributed to the air film trapped around the mesh surface. This novel superhydrophobic steel mesh material have wide applications on medical materials, marine materials and smart materials.
