LIGHT TRANSMITTANCE OF POLYMER-DISPERSED LIQUID CRYSTALS FORMED IN WEAK MAGNETIC FIELDS

The polymer-liquid crystal films formed by evaporation of solvent from the solution containing liquid crystal (derivatives of cyanobiphenyls) and polymer (polyvinyl acetate) in the presence of a magnetic field studied experimentally. It is shown that the use of weak magnetic fields of different directions during the formation of films orders the orientation of liquid crystals in one direction (the field is parallel to the plane of the film) or with a small angle of deviation of their axes from the surface of the film (the field is orthogonal to this plane). The change in the liquid crystal texture in the film results in the change of their light transmittance and dynamic characteristics in electric fields.
