title: A novel fluorinated polyimide surface with petal effect produced by electrospinning.
abstract: 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/or micro 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.
