摘要
The dielectric anisotropy and the response time of polymer-dispersed liquid-crystal films mixed with various nanoparticles were measured. The different types of nanoparticles used included metallic, dielectric, and biphasic core-shell or Janus type nanoparticles. Two methods were used for the determination of the dielectric anisotropy: a bridge method and a current-voltage method. The dipole moments of the nanoparticles were measured by the method of diluted solutions (Debye method). It was shown that the dielectric anisotropy plays a crucial role in the electro-optical properties of modified liquid crystals which in turn depend on the dipole moment and thus on the physical nature of the introduced nanoparticles.
