摘要

The invention concerns a method for preparing a functionalized nanoporous track-etched β-PVDF membrane, this method comprising the steps of :- considering a β-PVDF membrane with nanoporous channels,- using the radicals to initiate radical polymerization controlled by RAFT mechanism with a monomer in the nanoporous channels by- immersing the polymer membrane in an aqueous solution containing said monomer and a RAFT agent dissolved in the aqueous solution,- purging oxygen from the aqueous solution,- putting a sealable casing containing the aqueous solution and the membrane into a thermostated water bath during a predetermined time with a predetermined temperature to reach a predetermined grafting yield.
