Herein, we present a new series of liquid crystal elastomers (LCEs) incorporating various amount of polyrotaxane cross-linkers (PR-LCEs), and investigate their structure-property relationship. Toughness and damping property of the PR-LCE can be maximized at optimum PRX content (0.5 wt%), while preserving the thermally-driven reversible actuation of the LCE. Interestingly, dynamic nature of PR crosslinker along with shape memory property of LCE enables thermally-induced self-healing, which is ineffective for the pristine LCE under the same condition. |
