Bibliographic description in the original language

Kusova , A.M. Nanopore confinement and fluid behavior in nanocellulose–based hydro- and organogels /A.M. Kusova, R.Z. Safieva, O.I. Gnezdilov, O.S. Zueva, V.V. Salnikova, Yu.F. Zuev// Carbohydrate Polymer Technologies and Applications. - 2021. - N.2. - P. 100111-100119.

Annotation

The morphology of nanofibrillated cellulose (NFC) systems are probed with water and organic ester as the tracers to determine the porous structure of NFC skeleton. The analysis of NMR and SEM data for water and ester NFC-based gels have shown the essential difference in nanoscaled organization of cellulose supramolecular structure. It was shown, that the average size of free porous medium decreases dramatically during the transfer of nanocelllose fibrils from inorganic water phase to the organic ester one. The replacement of water by ester provides the transfer of nanofibrilles to more dispersed state at the nanoscale. FTIR experiments have shown the formation of long-living hydrogen bonds with solvent molecules stabilizing the NFC gel structure in a gel-like structures. Due to increasing of NFC specific surface area the properties of engineered biogreases on the basis of nanocelllose fibrils and organic ester could be regulated.
