摘要：

Dielectric relaxation in ferroelectric composite nanocrystalline cellulose - triglycine sulfate in the frequency range from 10(3) to 10(6) Hz in a weak measuring field (1 V center dot cm(-1)) from room temperature to the phase transition temperature of these composites (+54 degrees C) has been investigated. Two series of nanocomposites were used: the first one with the perpendicular directions of nanochannels with respect to the sample surface and the second one - with parallel. The typical for single-crystal triglycine sulfate maximum of the imaginary part of dielectric permittivity at frequencies (10(5)Hz - 10(6)Hz) in the case of composites nanocrystalline cellulose - triglycine sulfate is shifted to the range of lower frequencies (10(4)Hz - 10(5)Hz).
