Abstract

Abstract:

Based on the high reactivity of carboxyl and epoxy groups, crosslinked polyolefins were successfully prepared by reactive blending of ethylene-glycidyl methacrylate copolymer(PE-GMA) and ethylene acrylic acid copolymer(EAA). The thermodynamic properties and shape memory effect of the obtained polymer were measured by differential scanning calorimeter(DSC) and dynamic mechanical thermal analyses(DMA). The dual-shape memory effect, multi-shape memory effect and two-way shape memory effect were achieved due to the broad distribution of crystallite sizes of the crosslinked polyolefins. By the aid of photothermal effect of graphene oxide(GO), photothermal-induced shape memory effect was also realized. The “temperature gradient” strategy was successfully applied to the photothermal-induced two-way shape memory effect of the crosslinked polyolefins.

Key words: crosslinked polyolefins, shape memory effect, photothermal effect, temperature gradient
