Shape memory polymers (SMPs) are smart materials that can have temporarily deformed shape and remember their original shape under external stimulus like a temperature. For the polymer to show shape memory behavior, it should form a network structure, which can be obtained by either chemical or physical crosslinking. In this study, SMPs were prepared by chemical crosslinking of glycidyl containing ethylene copolymer with end-carboxylated Diels-Alder (DA) adduct synthesized from furan carboxylic acid and bismaleimide. The ethylene copolymer crosslinked by the DA adduct exhibited an excellent thermally triggered shape memory effect when the temporarily fixed shape was heated above their crystalline melting temperature. It also showed thermal reversibility and self-healing behavior, which was confirmed by FTIR, DSC, solubility test and tensile test. |
