Dataset of the article: Green oleogels based on elm pulp cellulose nanofibers: effect of the nanofibrillation pre-treatment on their thermorheological behavior

Description

This dataset reports the thermo-rheological behavior of sustainable oleogels prepared by dispersing cellulose nanofibers, both mechanically refined and TEMPO-mediated oxidation chemically treated, from bleached elm kraft pulps in castor oil (1.4 wt.%). A methanol-mediated solvent-exchange method was used to transfer the nanofibers from hydrogel to oil. Rheological data under linear and non-linear shear conditions highlight the influence of the nanofibrillation pre-treatment on mechanical stability, shear resistance, temperature sensitivity, and structural recovery of the oleogels. Cellulose nanofibers, both mechanically refined and TEMPO-mediated oxidation chemically treated, were obtained from bleached elm kraft pulps and supplied as aqueous gel suspensions. Oleogels were prepared by transferring these nanofibers into castor oil (1.4 wt.%) via a methanol-mediated solvent-exchange method that displaced water and enabled their dispersion in the oil. The thermo-rheological behavior of the resulting oleogels was characterized through viscous flow and small/large amplitude dynamic shear tests over a range of temperatures and stress conditions to evaluate the influence of the nanofibrillation pre-treatment on shear resistance, temperature sensitivity, and structural recovery.
