An optimization of microwave-assisted grafting of poly(N-isopropylacrylamide) (PNIPAM) onto nylon-6 porous film for thermo-responsive gating membrane

This work focused on a fabrication of smart membranes using a novel grafting method comprising of plasma peroxide technique together with microwave-assisted polymerization. PNIPAm, thermo-responsive polymer, both with and without crosslinker, were grafted onto porous Nylon-6 membranes. Key parameter...
