我们首先通过自下而上的过程制备了基于垂直纳米针分形结构的水接触角为178°的超疏水薄膜。迄今为止，只有原始水接触角大于90°的材料（被归类为疏水性）才能根据可能的分形结构，通过自上而下的过程来制备超疏水膜（>170°）。现在，在这项工作中，基于由直径为6.5 nm的纳米尺寸针制造的超疏水表面的理想分形结构，使用原始接触角为75°的月桂酸涂层薄膜可以实现约178°的水接触角，这被归类为亲水性。
We first fabricated the superhydrophobic film with a water contact angle of 178° based on a perpendicular nanopin fractal structure by a bottom-up process. Until now, only materials with an original water contact angle larger than 90°, which is classified as hydrophobicity, could be used to fabricate the superhydrophobic film (>170°) according to the possible fractal structure by a top-down process. Now, in this work, a water contact angle of about 178° can be achieved using a lauric acid-coated film with an original contact angle of 75°, which is classified as hydrophilicity, based on an ideal fractal structure for the superhydrophobic surface which is fabricated by the nanosize pin with 6.5 nm diameter.
