Dielectric Properties of Lyotropic Magnetic Liquid Crystal

Abstract

An important feature of lyotropic liquid crystals is the self-assembly of the amphiphilic molecules as supermolecular structures. We have studied the formation of nematic liquid crystal phase in solutions containing lysozyme amyloid brils and magnetic nanoparticles using oscilloscopic method. Interaction of brils with magnetic nanoparticles under the external magnetic eld resulted in bril re-arrangement. The analysis of the obtained results suggests that the decrease in conductivity of solutions in presence of magnetic eld is due to decrease of the ion mobility caused by re-arrangement of structures in the solution. The obtained results allow determination of the optimum ratio of the components which can lead to preparation of solutions with a more ordered structure in presence of magnetic field.
