超疏水表面对水滴具有很强的粘附性，由于其独特的应用而引起人们的极大关注。在这篇文章中，我们提出了一种方法来构建这样的表面具有相当强的固体-水粘附力。采用静电纺丝法制备了一种新型的含氟聚酰亚胺（FPI）纳米纤维连接的碗状凹陷纳米粒子。由这种结构组成的表面呈现出强大的超疏水性以及超高的粘附性。建立了一个物理模型来解释革命性的静电纺丝结构上高粘附力的产生。
Superhydrophobic surfaces with strong adhesion to water droplets are drawing great attention due to their unique applications. In this communication, we propose a method to construct such surfaces with considerably strong solid-water adhesion. A novel fluorinated polyimide (FPI), was electrospun into dented nano and/ormicro bowl-like particles linked with nanofibers. Surfaces consisting of such structures present robust superhydrophobicity as well as ultra high adhesion. A physical model is built to explain the generation of high adhesion on the revolutionary electrospun structures.
