Abstract | Thermally healable epoxy natural rubbers (ENR) are being extensively researched for extending their lifespan. Unfortunately, increasing the healing ability often leads to reduced mechanical property due to the mutually exclusive governing mechanisms. Herein, we report biobased elastomers based on ENR, polylactide (PLA) and layered double hydroxide (LDH) through the first exfoliation of LDH into monolayer LDH (E-LDH) by melt-blending with PLA and then with ENR. The presence of E-LDH can promote the formation of more β-hydroxyl esters between PLA and ENR, which improve the healable ability of nanocomposites owing to more transesterification reaction, and the entanglement of both PLA and ENR chains with E-LDH. With the inclusion of 1.0 wt% E-LDH, the tensile strength and strain at break of the PLA/ENR binary blends increase by 32% and 10%, respectively. Moreover, a maximum microcrack healing efficiency is up to 123%. Moreover, the thermally recyclable E-LDH/PLA/ENR nanocomposites nearly retain their mechanical properties. |
