本文报道了一种简单的水热法在聚酰亚胺（PI）上原位制备分级CuO球。在引入低表面能的涂层后，超疏水性被赋予所得膜，其中水滴的润湿状态可以通过简单地调节CuO的微/纳米结构来很好地控制。特别是，超疏水表面可以抵抗酸碱腐蚀，高温和低温，冲洗和超声波处理，对这些极端处理显示出高耐久性。此外，该膜对有机和无机粉尘具有自清洁性能。我们相信，具有自清洁功能的超疏水性和柔性PI膜在实际户外应用中具有极大的兴趣。(C)2016爱思唯尔B. V.保留所有权利。
A simple hydrothermal method is reported here to in-situ fabricate hierarchical CuO spheres on polyimide (PI). After introducing a coating layer of low surface energy, superhydrophobicity is imparted to resultant films, where the wetting state of water droplet can be well-controlled by simply adjusting the micro/nano-structures of CuO. Particularly, the superhydrophobic surface can resist acid-and base-corrosion, high and low temperatures, flushing and ultrasonication, showing high durability against these extreme treatments. In addition, the film has a self-cleaning property toward organic and inorganic dusts. We believe the superhydrophobic and flexible PI films with self-cleaning function are of great interest to practical outdoor applications. (C) 2016 Elsevier B.V. All rights reserved.
