## Abstract Acrylic acid (AA)β__g__βpolypropylene (PP) membranes were prepared by grafting AA on to a microporous PP membrane via plasmaβinduced graft polymerization. The grafting of AA to the PP membrane was investigated using Fourier transform infrared spectroscopy (FTIR). Poreβfilling of the mem
Surface-charge-mosaic-modified ultrafiltration membranes with charged domains of various sizes (500, 100, or 50 mm) were prepared by two-step laser-induced surface graft polymerization using a striped photomask. First, the surface of an ultrafiltration membrane was treated with 4-vinylpyridine after
