Rheology of Pickering Emulsions Stabilized and Thickened by Cellulose Nanocrystals over Broad Ranges of Oil and Nanocrystal Concentrations

The rheology of oil-in-water (O/W) emulsions, stabilized and thickened by cellulose nanocrystals, also referred to as nanocrystalline (NCC), was investigated over broad ranges NCC oil concentrations. concentration varied from 1.03 7.41 wt% based on the aqueous phase. emulsion approximately 10 70 wt%. emulsions produced were highly stable with respect creaming coalescence. non-Newtonian in that they exhibited strong shear-thinning behavior. rheological data described adequately a power-law model. consistency index (K) flow behavior (n) strongly dependent At fixed concentration, increased whereas decreased increase concentration. A similar observed when increased; is, decreased.
