Fabrication of Superhydrophobic Polyacrylonitrile (PAN) nanofibres membranes for membrane distillation technology

Membrane distillation (MD) is a promising water desalination technology that is capable of treating high salinity water. However, the problematic fouling issues and membrane wetting are the primary impediments to the large-scale application of this technology. To overcome the mentioned problems, the...
