Controlled pore size, thickness and surface free energy of super-hydrophobic PVDF® and Hyflon®AD membranes

Super-hydrophobic membranes were manufactured by using two per-fluorinated polymers such as PVDF and Hyflon AD. The combination of controlled structure and supra-molecular chemistry made these membranes ideal interfaces to be used in membrane contactors.

Super-hydrophobic per-fluorinated membranes were prepared by controlling kinetic and thermodynamic parameters of the manufacturing process. Pore size and thickness were modulated, narrow distribution was maintained and water repellence was improved. The control of the membrane morphology and physicochemical properties make
