摘要

Abstract

A series of fluorinated phosphatidylcholine polyurethane macromolecular additives were synthesized by solution polymerization using methylenebis(phylene isocyanates) (MDI) and 1

4-butanediol (BDO) as hard segments

a new phoshporycholine

2-(2

9-hexadecafluoro-10-(2-hydroxyethoxy)decyloxy) ethyl phosphorycholine (HDFOPC) as end-capper

and four polydiols

poly(tetramethylene glycol)s (PTMG)

polydimethylsiloxane (PDMS)

poly(1

6-hexyl-1

5-pentylcarbonate) (PHPC) and poly(propylene glycol) (PPG) as soft segments

respectively. The chemical structures of the synthesized polyurethanes were characterized by

H-NMR and FTIR. DSC and DMA were employed to study the phase behavior of these novel polyurethanes due to their great influences on the surface properties

and hence their interactions with bio-systems. The results showed that phase separation of the fluorinated phosphatidylcholine end-capped polyurethanes was increased in comparison with that of normal polyurethanes. The effect of fluorinated phosphatidylcholine end-capped groups on the phase behavior was further demonstrated by analyzing the degree of hydrogen-bonding between hard and soft segments.
