Facile Preparation Of Superhydrophobic Membrane Inspired By Chinese Traditional Hand-Stretched Noodles

A facile approach inspired by Chinese traditional hand-stretched noodle-making process has been demonstrated for the preparation of superhydrophobic membrane for the first time. Unlike standard electrospinning, a metal substrate that is covered with superhydrophobic nanopowders is utilized to collect fibers during electrospinning. Experimental results show that the proposed method can make some nanopowders stick on the fiber surface to endow electrospun membranes with superhydrophoboic property, especially as the substrate is heated. This noodle-making-like electrospinning process is believed to provide a novel and simple way for the fabrication of superhydrophobic membrane, which should further broaden the application of electrospinning technique.
