Oil in water emulsions have been stabilized by functionalized cellulose nanofibrils, bearing either negative (oxidized cellulose nanofibrils, OCNF), or positive (cationic cellulose nanofibrils, CCNF) surface charge. The size of the droplets was measured by laser diffraction, while the structure of the shell of the Pickering emulsion droplets was probed using small angle neutron scattering (SANS), confocal laser scanning microscopy (CLSM), scanning electron microscopy (SEM) and rheology measurements. Both OCNF and CCNF-stabilized emulsions present a very thick shell (>100 nm), comprised of densely packed CNF. OCNF stabilized emulsions proved to be salt responsive, influencing the droplet aggregation and ultimately the gel properties of the emulsions; while CCNF emulsions, on the other hand, showed very little salt-dependent behavior.
