The dielectric properties of celluloze and nano-celluloze were investigated by method of broadband dielectric spectroscopy BDS in the low frequency (1·10 -2 - 1·10 6 Hz) and low temperature (173-273 K). The main relaxation process observedes on dielectric loss spectras determined as a β -relaxation, related with segmental dynamic of macromolecule of celluloze. The quantitative analys of dielectric spectra was carried out using the model equation of Gavrilyak-Negami (HN) with a conductivity term and estabilished diferences of relaxtion parameters and activation energies of simple celluloze and nano-celluloze.
