Abstract:
This study explores the incorporation of liquid crystals (LCs) into hydrogels while addressing
challenges associated with the inherent incompatibility between hydrophobic LCs and hydrophilic hydrogels.
Utilizing direct oil-in-water miniemulsions,1 non-polar LC droplets were first dispersed in an aqueous
medium, overcoming issues of coalescence and Ostwald ripening, followed by the addition of a solution of
hydrogels precursor. The LC-embedded hydrogels exhibited an electro-optical response, manifested as an
increase in the optical transmittance (lower turbidity) upon the application of an external bias. This change
was ascribed to the positive dielectric anisotropy of LCs confined in the droplets. Differential scanning
calorimetry revealed a shift in the nematic-isotropic phase transition towards lower temperatures in the
miniemulsion and LC/hydrogel, suggesting a reduced anchoring energy due to confinement in the droplets. In
addition, rheological characterization showed that LC-embedded hydrogels retained the mechanical properties
of the gel state but with both the storage and loss moduli becoming higher. This work presents a route towards
making electro-optically switchable hydrogels that can be developed into stretchable displays
