Abstract
Described herein are various embodiments for liquid crystal elastomers (LCE) formed from liquid crystalline monomers having 4-(6-(acryloyloxy)n-oxy)phenyl-4-(6-(acryloyloxy)m-oxy)benzoate (CnBAPE) as the mesogenic core. The LCEs described herein have improved thermotropic characteristics, including lower thermotropic activation temperatures. The LCEs described herein may also incorporate azobenzene to thereby also enhance the phototropic properties of the LCE.
Claims15
A liquid crystal elastomer, comprising:
- a first liquid crystalline monomer having a first mesogenic core;
- a second liquid crystalline monomer having a second mesogenic core;
- a third liquid crystalline monomer having a third mesogenic core;
- wherein the first mesogenic core, the second mesogenic core, and the third mesogenic core are all different;
- and
- wherein the first mesogenic core comprises 4-(6-(acryloyloxy)n-oxy)phenyl-4-(6-(acryloyloxy)m-oxy)benzoate, with n being any one of pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, and m being any one of pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl.
