Surface self-assembled zwitterionization of poly(vinylidene fluoride) microfiltration membranes via hydrophobic-driven coating for improved blood compatibility

Effect of surface modification of PVDF microfiltration membranes by PPO-b-PSBMA copolymer on resistance to fibrinogen adsorption and platelets adhesion. The modified surface resists the adsorption of plasma protein through the establishment of a hydration layer surrounding the hydrophilic segments of the copolymer, and therefore presents an improved hemocompatibility.194
