Paper Abstract

Shape memory polyurethane with different hard and soft segment based on aromatic diisocyanate (MDI) and polytetrahydrofuran (PTHF) or Polyethylene glycol (PEG) were synthesized by the prepolymer method. Glass transition temperature was tested by DSC. XRD results showed that the series of shape memory polyurethane has no crystallinity. And the shape memory behavior was also discussed. The results showed that the shape memory polyurethane made up of TMP-PTHF(1000)-MDI (2:1:5) performs better. It can recover 80% of original shape within one more second in the range of 37-45°C. SMPU films with PTHF as soft segment have good blood compatibility.
