摘要：
Polymer dispersed liquid crystals (PDLCs) are currently considered as promising materials for specific applications such as creation of window blinds controlled by electric field, fog simulators, UV protective glasses, etc. The samples consisted of liquid crystal 6CHBT dispersed in polyvinyl alcohol and doped with spherical or rod-like magnetic particles showed significant changes in the effective value of the permittivity in the frequency range 0.1 Hz - 10(6) Hz. In this frequency range the conductivity of PDLC has two components: the ions in LC and the electrons in polymer. The presence magnetic particles in PDLC increases the ion component of the conductivity as well as the electron component of the conductivity.
