Abstract

The structure factor of the lyotropic liquid-crystal cesium perflouro-octanoate water after the material has been quenched form the isotropic phase to the nematic phase was found to display non-Porod power-law behavior in the limit of large wave vectors. Our measurements were consistent with the scaling law S(q,t)t-3/2q-6 for bulk samples and S(q,t)t-1q-4 for thin samples exhibiting two-dimensional behavior. Dimensional crossover was also observed.
