| Abstract: | A novel poly(urethane-urea) shape memory polymer (PUU SMP) was synthesized from poly(DL-lactic acid) (PDLLA) Diols, hexamethylene diisocyanate(HDI) and butanediamine(BDA), aiming to develop a biodegradable and biocompatible shape memory polymer. Its structure, thermal properties and shape-memory behaviors were characterized through Fourier transform infrared spectrometry (FTIR), differential scanning calorimetry (DSC) and bending test. The results showed that the response temperature for shape memory of PDLLA–PUU SMP is dependent on the polymeric glass transition temperature and this polymer has an excellent shape memory effect, having the ratio of the shape-memory fixation approximately 100% and the ratio of the shape-memory recovery about 98%. |
