Abstract
The present disclosure provides a stable aqueous composition comprising an aqueous component, a hydrophobic complex comprised of a multivalent metal salt complexed with nanocellulose fibers and lignin, with the composition exhibiting a viscosity sufficient to prevent coalescing and settling of the hydrophobic complex in the aqueous component. The composition may be used to coat surfaces of articles to produce a hydrophobic surface. Once applied to the surface, the aqueous coating is spread to form a wet film covering the surface and is then dewatered and dried to produce a dried hydrophobic coating.

A composition, comprising;
- an aqueous component and a hydrophobic complex comprised of a multivalent metal salt complexed with nanocellulose fibers and lignin, the composition exhibiting a viscosity sufficient to prevent coalescing and settling of the hydrophobic complex in the aqueous component.
A method of producing a stable suspension, comprising:
- mixing nanocellulose fibers in an aqueous solution along with solubilized lignin with a multivalent metal salt under conditions suitable for the nanocellulose fibers, the multivalent metal salt and the solubilized lignin to form a hydrophobic nanocellulose fiber complex to give a suspension of the hydrophobic nanocellulose fiber complex in an aqueous component exhibiting a viscosity sufficient to prevent coalescing and settling of the hydrophobic complex in the aqueous component such that the hydrophobic nanocellulose fiber complex exhibits stability in the aqueous solution.
A method of producing a hydrophobic surface, comprising;
- applying a composition to a surface of an article, the composition comprising
- an aqueous component and a hydrophobic complex formed by a multivalent metal salt complexed with nanocellulose fibers and
- solubilized lignin, the composition exhibiting a viscosity sufficient to prevent coalescing and settling of the hydrophobic complex in the aqueous component;
- and
- spreading the composition to form a wet film covering the surface and dewatering the wet film to produce a dried coating.
