Study on the stability of hybrid dispersions of cellulose nanocrystals and aluminum oxide

Abstract

Hybrid dispersion systems based on cellulose nanocrystals (CNC) and aluminum oxide have been prepared, and the influence of the ζ-potential on their stability has been studied for a wide range of the concentration ratio of the components. Their influence on the morphology and properties of the hybrid particles is evaluated. It is established that one can obtain stable colloidal dispersions with both negatively and positively charged particles or hybrid systems with a neutralized surface charge by controlling the surface potential.
