Optically isotropic liquid crystals with microsized domains

We offer a new type of polymer-stabilized liquid crystal (PS-LC) in which mesogenic monomers doped in a LC medium are photocured at a temperature where the LC medium is in the isotropic liquid phase. If the LC domain size could reduce less than the wavelength of visible light, optically isotropic LC media may be realized. We researched the effect of the concentration of polymer and the UV intensity on the LC domain size. The domain size decreases as the polymer concentration increases and the LC medium may become almost isotropic. Moreover, we can obtain a perfectly isotropic LC medium with a high intensity of UV irradiation.
