Liquid crystalline elastomers (LCE) are interesting smart materials which are capable of reversible deformation (i.e., actuation) through a reversible change in their order parameter by external stimuli such as heating/cooling and light or chemical exposure. Here, we report the one-pot synthesis a series of LCEs by aza-Michael addition between diacrylate-functionalized LC monomer and alkyl-amines, followed by photo crosslinking. Structure-property relationships of the resulting LCEs are investigated, which demonstrate thermal, mechanical and actuation properties of LCEs can be efficiently manipulated by the choice of alkyl amines. The facile synthesis of tailorable and programmable LCEs may expedite their functions as adaptive materials including smart sensors as well as morphing devices in biomedical and aerospace engineering. |
