Hemocompatibility and antifouling properties of PEGMA grafted Polyethersulfone/aminated halloysite nanotubes mixed matrix membrane

The aim of this study was to evaluate the permeation performance and hemocompatibility of polyethersulfone (PES) membrane after mixing with halloysite nanotubes (HNTs), followed by grafting poly (ethylene glycol) methyl ether metacrylate (PEGMA). HNTs were modified by (3-aminopropyl)triethoxysilane (APTES) to facilitate dispersion in PES matrix. Incorporation of 2wt% HNTs not only could increase water permeability of the PES membrane from about 580 to 840 L/m(2).h.bar, but also improved mechanical strength of the membrane and could be an appropriate sublayer for composite membrane preparation. Grafting PEGMA could inhibit proteins attachment and platelets adhesion on the PES mixed matrix membrane.
