NEMATIC LIQUID CRYSTAL MIXTURESWITH STABLE HOMEOTROPIC BOUNDARY CONDITIONSAND METHODS OF MAKING THE SAMEAbstract of the DisclosureNematic liquid crystal mixtures characterized bya homeotropic boundary condition are prepared by theaddition of soluble monopolar compounds to either positiveor negative dielectric anisotropic nematic materials.Between approximately 0.5 and 5 percent by weight ofcompounds such as carboxylic acids, aliphatic amines andaliphatic nitriles, for example, when dissolved in a nematicmaterial produce spontaneous homeotropic boundary conditionstherein.
