Dataset of the article: Exploring the effect of the pulp bleaching on the thermo-rheological behavior of sustainable cellulose nanofiber-based oleogels

This dataset reports the thermo-rheological behavior of sustainable oleogels prepared by dispersing cellulose nanofibers from bleached and unbleached 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 pulp bleaching on mechanical stability, shear resistance, temperature sensitivity, and structural recovery of the oleogels.
Cellulose nanofibers were obtained from bleached and unbleached 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 pulp bleaching on shear resistance, temperature sensitivity, and structural recovery.
