Abstract

Hydrophilic surfaces based on grafted poly(2-methacryroyloxyethyl phosphorylcholine) (poly(MPC)) were prepared by surface-initiated photo-induced radical polymerization on polydimethylsiloxane (PDMS). The quantity of grafted poly(MPC) were checked via the ratio of MPC to initiator. The surfaces were characterized by X-ray photoelectron spectroscopy (XPS) and static contact angle (STA) on water. The amounts of adsorbed initiator on PDMS before grafting were detected by UV absorption The surface compositions of N and P on PDMS increased with increasing the initiator concentration in feed. The adsorbed initiator on PDMS surface was proportional to the initial initiator concentration. The STA on PDMS surfaces greatly reduced from 114.7 to 45.7 by the modification of poly(MPC) grafting. This result suggest the modified PDMS act as a novel medical elastomer with possessing both anti-fouling property and high oxygen permeability.
