Abstract / Full Text

Optical properties of polymer-liquid-crystal composites (PLCCs) with controlled surface adhesion during uniaxial deformation have been studied. It has been experimentally shown that in PLCCs based on the 4-nheptyl- 4'-cyanobiphenyl nematic liquid crystal, the phenomenon of optical hysteresis can be observed during uniaxial deformation. The structure of such a film is a polymer matrix, in the volume of which elongated nematode droplets are distributed randomly, the long axes of which are oriented mainly along the direction of film stretching. The results of this work can be used used for creating elements of static memory for recording and long-term storage of information and optical switches of bistable states.
