【Abstract】 Superhydrophobic surface with high solid/liquid adhesion is of great fundamental and echnological importance.However,the fabrication of adhesive superhydrophobic polymer surfaces with high stability is rare,which limits the utilization of such surfaces in harsh environment.This paper illustrates a simple electrospinning way to produce fluorinated polyimide nanofibric mat with adhesive superhydrophobicity as well as high thermal stability.Water contact angle on the mat reaches as high as 158°and the adhesive force to water drop is up to 98μN.Moreover,the mat is able to stand extreme heat up to 300°C.By virtue of the facile electrospinning technique,large-area flexible mats can be easily achieved.Such electrospun fluorinated polyimide mat will possess more broad applications than ordinary organic superhydrophobic surfaces owing to its excellent stability in harsh environment.更多还原
