Preparation of Highly Adhesion Hydrophobic Membrane and Superhydrophobic Membrane via Electrospinning

Abstract

Membranes with superhydrophobicity have attracted much attention in recent years for improving self‐cleaning in practical applications. In this study, highly‐adhesion hydrophobic membranes and superhydrophobic membranes were prepared and used for preciously rare droplets transportation and efficient oil‐water separation separately. The two types of membranes with different applications were prepared by electrospinning and the morphology and structures of the electrospinning membranes were adjusted by regulating serious of parameters including voltage, flow rate and the diameter of the spinning needle. The as‐prepared membranes with apparent superhydrophobicity were fluorine‐free, environmentally friendly materials and realised effective and rapid oil‐water separation; moreover, the membranes exhibit excellent adhesivity when measured by the video‐optical contact angle system, and the maximum adhesion amount was 80 μL. The two membranes reported here were easily fabricated and reproducible, with adhesive and superhydrophobic properties, respectively. so we envision that the membrane has the potential to be used in a variety of practical applications such as the development of robots that require non‐destructive liquids transportation, efficient oil‐water separators and so on.This article is protected by copyright.
