Abstract
The efficiency of the pulsed NMR method in studying phenomena in the interphase layer of biopolymer-water systems within the framework of the Gibbs thermodynamic theory was examined. Relationships between the nuclear magnetic relaxation times and the chemical potential and surface tension coefficient at the interphase interface of the adsorption system were established. How the thermodynamic and relaxation parameters change during the formation of the adsorption Gibbs layer on various cellulose samples was demonstrated. An analysis of the state of the water in the adsorption layer was performed, and its mean thickness was determined.
