The Stability of Liquid Crystal-in-Water Dispersions Stabilized with Copolymers of Acrylamide
A mixture of nematic liquid crystals, E-7, was dispersed by using several water soluble acrylamide copolymers. The copolymers were synthesized by copolymerization of acrylamide with hydrophobic monomers such as styrene and methyl methacrylate. The steric stabilization of the liquid crystal-in-water dispersion was achieved by these copolymers. It was found that preferential adsorption hydrophobic moieties onto the liquid crystal droplet surface resulted in steric stabilization of the dispersion. This stable liquid crystal-in-water dispersion can be used to fabricate nematic curvilinear aligned phase from aqueous polymer systems.
