Preparation of porous ion‐exchange membranes from sulfonated polyethylene/poly(styrene‐co‐divinylbenzene)

Abstract: It was shown that the etching of styrene-divinylbenzene copolymer from KESD-2 type ion-exchange membranes resulted in porous membranes. Modification of such membranes introduced both acidic or basic groups onto the pore surface. The ultrafiltration of bovine serum albumin through these membranes was mostly affected by coulombic interaction. Protein deposition on/in membrane was controlled by charge as well as hydrophilic properties of membranes. In addition, the effect of polystyrene crosslinking degree on the… Show more

“…When the preparation of a nanofiltration membrane appeals for the more careful examination, the antifouling activity of Porous Ion-Exchange Membranes is just well documented in literature 2,10,[13][14][15][16] . Having membranes with carboxylic groups on their surface one expects antifouling action of such materials.…”

“…Surface-hydrophilized membranes do not foul to the same extent as their unmodified analogues. Hence, the separation run may last much longer. Taking into account the economy of ultrafiltration, the longer the time of a membrane's service, the more profitable the processes. An additional advantage of surface modification is a chance to modify the membrane surface without any alteration of the bulk material properties.…”
