Biofunctional Membrane Substrates Based on Blends of Polyetherimide with Poly (Vinyl Pyrrolidone-Co-Vinyl Acetate)

Amorphous engineering thermoplastics such as polysulfone, polyethersulfone, and polyetherimide have been used for the fabrication of a wide range of membrane materials via phase inversion methods. The high glass transition temperatures inherent to these materials lead to glassy membranes which display excellent mechanical integrity for a variety of applications. The application of engineering thermoplastics as microporous substrates for biofunctional membranes is typically precluded, however, owing to a lack of suitable functional attachment sites on the membrane surface. Further, the hydrophobic nature of these materials leads to difficulties with protein adsorption (i.e. fouling) and wettability.
