The capability of several ionic liquids to dissolve cellulose compounds was exploited for the preparation of colloids with an improved stability. Thus, inorganic particles from the nanometer to the micrometer range were homogeneously dispersed in different solutions of cellulose in ionic liquids. The possibility of utilizing cellulose compounds either to manipulate some physical properties of the ionic liquids or to modify the surface the particles were investigated which may improve the stability of the colloids against sedimentation. The proposed approach may represent an inexpensive method for the preparation of “environmentally-friendly” composites with different functional properties.
