The bubble electrostatic spraying a new technology for fabrication of superhydrophobic nanofiber membranes

Le résumé fourni par la source

Researchers are excited about the latest advances in the long needle electrospinning and the bubble electrospinning, which have triggered wide-spread concern. This paper offers a new angle for modifying both methods, the former is developed into a modified one with an auxiliary helix needle, which is used for fabrication of super-hydrophobic polyvinylidene difluoride-copolypolyhexafluoropropylene nanofiber membrane (PH-E membrane for short), and the latter is extended to a bubble electrostatic spaying, which is used for spraying PDMS microspheres on the PH-E membrane surface, and the resultant membrane is called as the PDMS-PH-E membrane. Both membranes hydrophobicity, surface roughness, porosity, and wetting property are measured and compared, and the drop impact dynamical property of the PDMS-PH-E membrane has opened the path for a new way to design of self-clearing and anti-fouling and anti-wetting surfaces. Far-reaching applications of the membranes include energy harvesting devices and sensors. We anticipate this article to be a starting point for more sophisticated study of the bubble electrostatic spaying and PDMS-PH-E membrane advanced applications.
