Adsorption and dielectric properties of natural composite polymer wood

Abstract

The state of water in a natural polymer, wood, was studied by its eff ect on the dielectric parameters and currents of thermostimulated depolarization (TSD) of the adsorption system. It has been shown that surface wood hydroxyls do not play a signifi cant role in the adsorption of water, which occurs mainly in pores of varying volume. Interpretation of the behavior of the TSD currents showed that at the initial stage the polarization linearly depends on the water adsorption value, then this linearity is violated, which we associate with the onset of migration polarization.
