K. Fujimoto et al., POLYURETHANE SURFACE MODIFICATION BY GRAFT-POLYMERIZATION OF ACRYLAMIDE FOR REDUCED PROTEIN ADSORPTION AND PLATELET-ADHESION, Biomaterials, 14(6), 1993, pp. 442-448
Surface modification of polyurethane by glow-discharge treatment and s
ubsequent graft polymerization of acrylamide was studied. The modified
hydrophilic surfaces were characterized by the measurements of dynami
c contact angle and zeta potentials and examined for protein adsorptio
n behaviour and platelet adhesion. Data from in vitro and ex vivo expe
riments indicated a reduction of protein adsorption and platelet adhes
ion for the hydrophillic graft polymers, the extent of which was corre
lated to polymer graft density.
