Abstract
The sorption properties of native cellulose and the state of water adsorbed by its fibers are studied by measuring 1H NMR relaxation. A scheme of the supramolecular organization of cellulose microfibrils is proposed. A model of the monomolecular adsorption of water on the hydrophilic surface of cellulose is developed that considers the spatial arrangement of active sites and the characteristics of the formation of hydrogen bonds. A relationship between the pure heat of water adsorption on cellulose and the spin–spin relaxation times in layers of strongly bound water is established. A technique is proposed for determining the adsorption equilibrium constant, change in entropy, and surface tension at a solid–liquid interface.
