Natural cellulose coated dispersions: new opportunities in green process engineering and applications
June 19-24, 2016
Our recent discoveries have shown that cellulose chains could be molecularly dissolved in a solvent mixture of an ionic liquid with certain polar organic solvents, forming true solutions. Due to their molecular dissolution, the cellulose chains in hydrogels, formed by regeneration of these solutions, are also maintained in an amorphous structure. Furthermore, as was reported recently, cellulose solutions in other solvents, as well as suspensions of cellulose hydrogel particles, can be used as a novel amphiphilic coating for oil/water emulsification, by utilizing cellulose as an encapsulating agent that forms a stabilizing coating in oil-in-water and water-in-oil emulsions without the use of additional surfactants. Our innovative encapsulation process is cheap, “green” and uses simple fabrication methods (1-5).
We have studied cellulose dissolution, formation and structure of regenerated cellulose hydrogels and fragmented hydrogel dispersions. Furthermore, we studied the influence of fabrication processes on structural parameters of cellulose coated oil-in-water emulsions, as well as their enzymatic degradation.
