Grafting polymer from poly(ethylene terephthalate) films by surface-initiated ATRP
Surface-initiated atom transfer radical polymerization (ATRP) from poly(ethylene terephthalate) (PET) film was studied. Poly(methyl methacrylate) (PMMA), poly (acrylamide) (PAAM), and their diblock copolymer (PMMA/PAAM) on the surface of PET film were successfully prepared by surface-initiated ATRP. The structures and properties of the modified PET film were characterized by FT-IR/ATR, X-ray photoelectron spectroscopy (XPS), measurements of contact angles, and scanning electronic microscopy (SEM). The results indicate that the surface properties of PET film were greatly improved by grafted polymer. (c) 2007 Wiley Periodicals, Inc.
