Shape-Fixable Vitrimer Microarrays via Magneto-Thermomechanical Stimuli |
초록 |
Contactless actuation of magneto-responsive micropillar arrays have been reported by programming alignment of magnetic particles and/or geometry of the micropillars. However, after removing external magnetic fields, magnetic actuation disappears and micropillar arrays recover original shapes. In this study, we embedded hard magnet particles into epoxy vitrimer matrix to provide shape-fixability using transesterification after removal of external magnetic fields. Furthermore, we discuss trade-off relationships of mechanical stiffness and magnetization for the magnetic composites by developing structure-property relationships of the magnetic vitrimer composites according to the magnetic particle concentration. We will also discuss magnetically driven shape-fixation of the magnetic vitrimer composites by thermomechanical stimuli. |
