摘要

Asymmetric polyacrylonitrile (PAN) membranes (average pore size of about 12 nm) were used as support for polymeric PV separation phases which were in situ prepared by heterogeneous photo-initiated graft copolymerization. The impact of different substituted methacrylates or acrylates and preparation parameters (UV irradiation time, solvent, initiator and degree of grafting) were analysed using PV with toluene/heptane (20/80 wt-ratio; 80°C) as model feed. High selectivity and high permeate fluxes were achieved. Major reasons for the excellent performance were the small effective PV barrier thickness (< 5mm) and the covalent anchoring of the coated polymer.
