▎ 摘　　要

NOVELTY - Three-dimensional (3D) (M1) printing a shape memory polymer (SMP)-based ink, comprises: providing an SMP epoxy; curing the SMP epoxy at a first temperature to increase its viscosity to at least 500 centipoise (cP) and provide a first cured SMP epoxy; providing the first cured SMP epoxy to an extruder syringe; performing extrusion-based 3D printing of the first cured SMP epoxy to provide a printed SMP epoxy; freeze-spraying the printed SMP epoxy with a freezing agent at a second temperature of less than or equal to10degrees Celsius to provide a freeze-sprayed SMP epoxy; and curing the freeze-sprayed SMP epoxy at a third temperature to provide the SMP-based ink. USE - The method is useful for three-dimensional (3D) printing a shape memory polymer (SMP)-based ink. ADVANTAGE - The method: can print pure thermoset SMP epoxy without any physical cross-linkers or chemical modification; and excellent mechanical and thermal reinforcement in SMP.
