Controlled Grafting of S-Naproxen Imprinted Layer on PVDF Microporous Membrane by ATRP
Controlled grafting of S-naproxen-imprinting polymer layer on the poly(vinylidene fluoride) (PVDF) microporous was carried out by the surface-initiated atom transfer radical polymerization (ATRP). Polymerization time was used as the independent variable to manipulate the amount of grafted imprinting polymer on the membrane surface. SEM, SPM and UV spectrum were used to study the structural morphology and selectivity of membranes and probe the incorporation of imprinted polymer layer on the surface of PVDF membranes . Results indicate that the integration of ATRP and molecularly imprinted polymeriaztion realize preparation of molecular selective membranes and it is possible to tune selectivity and morphology in rational way by changing polymerziton times.
