Surface characteristics of polymer membrane plays a significant role in bioprocess such as separation, purification, and so on. Generally, hydrophilicity is recommended for better process efficiencies in various commercial biomedical engineering fields. However, omniphobic properties of these fields could be recommendable for better perfomance because those properties on the surface is more favorable in many reasons. In this study, we try to modify the commercial polyethersulfone (PES) membrane by combining two different coating procedures: electrospinning and spray coating. Poly(vinylidene fluoride) is used to form the nanofiber mat for the robust roughness by the electrospinning technique and various fluoro-silane materials is applied to modify the chemical properties of the surface by spray coating method. The modified membrane was analysed by scanning electron microscopy for surface morphology and characterized by the measurement of contact angle for anti-fouling properties. We also measured the permeabilities of membrane for water and bovine solution to test anti-fouling ability in a simulated bioprocess conditions.
