It is demonstrated that the threshold value of the electric Fredericks transition in the composite based on polyvinyl acetate with 35% weight content of nematic liquid crystal 5СВ (4-pentyl-4′-cyanobiphenyl) is observed at a voltage of 60 V. A cell and a circuit for measuring the dielectric permittivity of polymer composites with encapsulated liquid crystals in strong electric fields are described.
