Abstract

We have developed a method that allows determining the relative water quantity in amorphous and crystalline areas of cellulose materials using X-ray and thermogravimetric experimental data. In the present paper, by using this method, we showed that the amount of water in the crystalline region may reach 50% of the water amount that amorphous regions contain. Also, we built a structural model of water molecules that can occur in a crystal lattice.
