Abstract: In order to study the effect of polypropylene glycol diglycidyl ether (JH-230) on the basic properties of thermosetting shape memory epoxy resin, a novel shape memory hydrogenated bisphenol A epoxy resin was prepared by the hydrogenated bisphenol A epoxy resin (AL-3040), polypropylene glycol diglycidyl ether (JH-230) and isophorone diamine (IPDA) with different molar ratios between the AL-3040 and the JH-230. The molecular structures of the thermosetting shape memory epoxy resin were mea-sured by the flourier transform infrared spectroscopy (FT-IR), the glass-transition temperature (Tg) of the epoxy resin was studied by the differential scanning calorimetry (DSC), and the corresponding storage modulus and shape memory property were observed by the dynamic thermomechanical analyzer (DMA) and tensile-recovery shape memory test. Results showed that the flexibility of the epoxy resin increased and the Tg of the epoxy resin decreased with increased JH-230 content. The storage modulus of the epoxy resin decreased and the complete recovery time of the epoxy resin extended with increased JH-230 content. It was suggested that the flexibility, Tg and storage modulus of epoxy resin can be controlled by adjusting the JH-230 content, and the shape memory hydrogenated bisphenol A epoxy resin has good shape memory property.
