Preparation and Properties of Poly(ether imide) Ultrafiltration Membrane Modified with Polyether Diamine

Abstract:

In this study, the morphologies, the hydrophilicity, and the anti-fouling of poly (ether imide) (PEI) membrane modified with an aqueous solution of polyether diamine predominantly PEO backbone (PEO-diamine) were investigated. A decrease in water contact angle and an increase in water absorption ratio indicated the hydrophilicity of modified membrane. Scanning Electron Microscope (SEM) showed a thinner skin layer of membrane and pores on the membrane surface for modified PEI membrane providing an increment of pure water flux and a reduction of BSA rejection of membrane. Under the protein filtration study, it was found that the flux recovery ratio of modified PEI membrane was higher than that of the unmodified PEI membrane.
