With mPEG as hydrophilic segment, epoxy resin as hydrophobic segment and isoflurone diisocyanate as the linker, the amphiphilic macromolecule WEG which contains the epoxy group was prepared. The amphiphilic macromolecule WEG is able to co-assemble with fluorescer and epoxy resin E51 in a selective solvent (water) to form a water-based emulsion. The emulsion mixed with modified amine curing agent in a certain proportion and followed by crosslinking at room temperature can build shape memory polymer materials with photoluminescence (fluorescence) function. The structures and properties of WEG, emulsion and film were characterized by FTIR, NMR, GPC, nanometer particle size analyzer, fluorescence spectrometer and DSC. The results showed that the emulsion has good particle size stability. The shape memory polymer film has good photoluminescence function and can be restored to the original shape rapidly upon heating, and the shape recovery degree can go up to 94.3%.
