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 P̄ n ≈ 30 and P̄ n ≈ 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).
