TLDR
In this paper, a commercially available aromatic polyamide reverse osmosis (RO) membrane was chemically modified to improve its chlorine resistance and anti-biofouling property by free-radical graft polymerization of 3-allyl-5,5-dimethylhydantoin (ADMH) using 2,2′-azobis(isobutyramidine) dihydrochloride as an initiator.About:

Thin-Film Composite Polyamide Membranes Functionalized with Biocidal Graphene Oxide Nanosheets
TL;DR: Using amide coupling between carboxyl groups of graphene oxide and carboxy groups of the polyamide active layer, graphene oxide is irreversibly bound to the membrane and direct contact of bacteria with functionalized graphene oxide on the membrane surface results in 65% bacterial inactivation after 1 h of contact time.
