The Contribution of Oligomerization Reaction Chemistry to the Thermomechanical Properties of Surface-Aligned Liquid Crystalline Elastomers

Review Nanoscience & Nanotechnology

Synthesis and alignment of liquid crystalline elastomers

Katie M. Herbert et al.

Summary: Liquid crystalline elastomers (LCEs) combine the elastic properties of rubber with the anisotropic properties of liquid crystals, allowing for multifunctionality and responsivity through local orientation patterning. Advances in materials chemistry and processing have paved the way for the functional integration of LCEs in various fields.

Surface-Enforced Alignment of Reprogrammable Liquid Crystalline Elastomers

Tayler S. Hebner et al.

Summary: Liquid crystalline elastomers (LCEs) are materials capable of undergoing large deformations, and their thermomechanical response is due to the coupling of polymer network properties and disruption of order between liquid crystalline mesogens. LCEs prepared via thiol-Michael addition reaction can be programmed and reprogrammed with complex director profiles under surface-enforced alignment, achieving distinctive shape transformations.

Influence of Orientational Genesis on the Actuation of Monodomain Liquid Crystalline Elastomers

Tayler S. Hebner et al.

Summary: The orientational genesis of cross-linking in aligned LCEs significantly affects the thermotropic and phototropic deformation of these materials. LCEs prepared by mechanical and surface alignment exhibit differences in actuation temperatures and photoinduced strain generation.
