Method for preparing a functionalized nanoporous track-etched PVDF membrane with RAFT polymerization

摘要

The invention concerns a method for preparing a functionalized nanoporous track-etched ²-PVDF membrane, this method comprising the steps of :
- considering a ²-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.
