Abstract :
The dispersion of dielectric permittivity of the composite nanocrystalline cellulose - triglycine sulfate in the frequency range 103 - 106 Hz in a weak electric field in the range from room temperature to the phase transition temperature of this composite (+54 °C) was investigated. It was shown that the typical for triglycine sulfate maximum of the imaginary part of dielectric permittivity at frequencies (105 Hz - 106 Hz) in the case of composite nanocrystalline cellulose - triglycine sulfate lies at lower frequencies (104 Hz - 105 Hz).
