Membrane Modification via "Grafting-From" Method Without the Use of a Photoinitiator... 

As a rule, two methods are used for membrane modification via the grafting-from approach without a photoinitiator an immersion method when the membranes are irradiated while immersed in a monomer solution, and a dip method when the membranes are dipped in a monomer solution and then irradiated in nitrogen or another inert gas (Pieracci et al. 2000).

Grafting can also be applied for the surface modification of the membrane. Although the method should work for any polymeric materials, most of the recent works on membrane surface graft polymerization were on polyamide thin-film composite (TFC) membranes or porous polypropylene membranes.
