Hybridization of poly(2-methacryloyloxyethyl phosphorylcholine-block-2-ethylhexyl methacrylate) with segmented polyurethane for reducing thrombogenicity

- Block-type copolymers (B-PMEH) bearing phosphorylcholine (PC) group were synthesized.
- The B-PMEH was hybridized with segmented polyurethane (SPU) by solution casting.
- Good orientation of PC groups at a substrate-contacting surface.
- The block-type copolymer was anchored by the SPU surface stably.
- Platelet adhesion was inhibited at the substrate-contacting surface.
