Amine-Acrylate Liquid Single Crystal Elastomers Reinforced by Hydrogen Bonding.

ABSTRACT: Liquid crystalline elastomers (LCEs) have been considered one of the most promising material concepts for artificial muscles. However, accomplishing actuation of LCEs requires macroscopic alignment of the liquid-crystalline orientation in the rubbery network, which imposes challenges in the materials chemistry and processing. A two-stage curing strategy has been the dominating approach during last three decades. Despite its many successes, the method is difficult in practice and requires delicate experiential skills, dealing with intrinsic fragility of intermediate gels after the first crosslinking stage. Here, a robust fabrication method for monodomain LCE based on the amine-acrylate aza-Michael addition is developed, involving two readily commercially available components with no catalys
