摘要

A new phosphorylcholine

(6-hydroxy) hexyl-2-(trimethylammonio) ethyl phosphate (HTEP)

was synthesized andcharasterized. Segmented polyurethane (SPU) containing phosphorylcholine structure was synthesized based ondiphenylmethane diisocyanate (MDI)

soft segment polytetramethylene glycol (PTMG) and HTEP

with 1

4-butanediol (BD)as a chain extender. The existence of phosphorylcholine structure on the surface of SPU was revealed by attenuated totalreflectance Fourier transform infrard spectroscopy(ATR-FTIR)

X-ray photoelectron spectroscopy(XPS) and water contact angle measurements.The blood compatibilities of the polymers were evaluated by hemolytic testing and a platelet-rich plasma(PRP) adhesion experiment

which was viewed by scanning electron microscopy (SEM) with polyurethane as a reference.The novel segmented polyurethane containing phosphorylcholine structure showed improved blood compatibility.
