heal.abstract	The hydration mechanism of natural cellulose and microcrystalline cellulose is studied by water sorption isotherms measurement, as well as by thermally stimulated depolarization currents (TSDC) and Broad Band Dielectric Relaxation Spectroscopy (DRS), in the temperature range 77 - 300 K and the frequency range 10 - 106 Hz. The dependence of the hydration procedure on cellulose crystallinity is investigated and a comparison of results obtained by water sorption, TSDC and DRS is attempted. The behaviour of dc-conductivity and its role on the biological functions of living organisms is emphasized.	en
