Morphology and surface properties of high strength siloxane poly(urethane-urea)s developed for heart valve application
Abstract
A series of siloxane poly(urethane-urea) (SiPUU) was developed by incorporating a macrodiol linked with a diisocyanate to form part of the soft segment. The effect of this modification on morphology, surface properties, surface elemental composition and creep resistance was investigated. The linked macrodiol was prepared by reacting α,ω-bis(6-hydroxyethoxypropyl) poly(dimethylsiloxane)(PDMS) or poly(hexamethylene oxide) (PHMO) with either 4,4’-methylenediphenyl diisocyanate (MDI), hexamethylene diisocyanate (HDI) or isophorone diisocyanate (IPDI). SiPUU with PHMO-MDI-PHMO and PHMO-IPDI-PHMO linked macrodiols showed enhanced creep resistance and recovery when compared with Elast-EonTM 2A which is a commercial biostable polyurethane. Small and wide-angle X-ray scattering data were consistent with significant increase of hydrogen bonding between hard and soft segments with linked-macrodiols which improved SiPUU’s tensile stress and tear strength. These SiPUU were hydrophobic with contact angle higher than 101° and they had low water uptake (0.7%·w/w of dry mass). They also had much higher siloxane concentration on the surface compared to that in the bulk.
