Catalyst-free, Acrylic Vitrimers Consisting of β-Amino Esters |
| 초록 |
Herein, we present a new class of acrylate-based vitrimers containing tertiary amines which can serve as an internal catalyst for the network rearrangement. Our catalyst-free vitrimers show bond exchanges via both transesterification and dynamic aza-Michael reactions evidenced by stress-relaxation experiments, where the thermal relaxation was accelerated by increasing the concentration of hydroxyl groups. The ability to bond exchange in our vitrimers enables reprocessing and self-healing at elevated temperatures under mild pressure. Shape memory properties of the vitrimers were further characterized, exhibiting high shape fixing and shape recovery ratio. Our catalyst-free vitrimers that can show tunable mechanical properties as well as self-healing and shape memory properties may facilitate their use as sustainable polymeric materials. |
