Notes:
Surface modified poly(ethylene terephthalate) (PET) films with 2-(methacryloyloxy)ethylphosphorylcholine (MPC) and 2-(glucosyloxy)ethyl methacrylate (GEMA) moieties, PMPC-g-PET and PGEMA-g-PET, were prepared by graft copolymerization using an Ar plasma-post polymerization technique. The degrees of polymerization of the grafts PMPC and PGEMA were P̄n ≈ 30 and P̄n ≈ 40, respectively. The contact angle of the modified PET film decreased from θ = 68° (the original PET film) to θ = 26° for PMPC-g-PET and to θ = 43° for PGEMA-g-PET. The modified PET films adsorb less serum proteins than the original PET film. Egg yolk lecithin did not adsorb on PGEMA-g-PET but adsorbed on PMPC-g-PET. PMPC-g-PET showed activity for the inhibition of fibrin formation and no adhesion of mouse fibroblasts (L-929).
