Abstract
A bilayer electrospun membranes for treating hydraulic fracking wastewater via membrane distillation, and more particularly to bilayer electrospun membranes having an omniphobic layer to prevent low-surface tension solution wicking and an oleophobic antifouling surface to prevent foulant depositing on the membrane. Nanoparticles are decorated on the omniphobic surface through electrochemical interaction, which is coated with a fluorine monomer on the nanoparticles. A zwitterionic co-polymer is grafted using self-assembly between hydroxy groups on the antifouling surface generated by alkaline treatment and anchor segment epoxy groups on zwitterionic co-polymer.
