Abstract |
This study is to investigate the thermomechanical properties according to the change of hard and soft segment ratios and diol types of polyurethane-based thermoset shape memory polymers(SMPs). SMP films were prepared by reaction of IPDI-prepolymer and three-functional polycaprolactone(PCL) diol. The three kinds of IPDI-prepolymers were synthesized with three different diols that were bisphenol-A, polyoxyethylene bisphenol-A ether and polytetramethylene ether glycol(PTMEG). Also, each IPDI-prepolymer was designed to have different isocyanate equivalent weight. the glass-transition temperature was characterized by dynamic mechanical analysis(DMA), fixity and recovery ratios are investigated using universal testing machine(UTM). |
