S. Belfer et al., SURFACE MODIFICATION OF COMMERCIAL POLYAMIDE REVERSE-OSMOSIS MEMBRANES BY RADICAL GRAFTING - AN ATR-FTIR STUDY, Acta polymerica, 49(10-11), 1998, pp. 574-582
A new grafting procedure was developed for surface modification of com
mercial polyamide reverse osmosis membranes. Acidic and neutral acryli
c monomers and sulfo-containing vinyl monomers were successfully graft
ed from aqueous solutions under mild conditions. The modifications wer
e monitored by ATR-FTIR spectra. The characteristic peaks of functiona
l groups introduced by grafting were evaluated. The spectral findings
correlated with physicochemical properties of the membranes.
