Abstract
This document provides polymer compositions (e.g., biopolymer compositions) and coatings. For example, methods and materials related to polymer compositions (e.g., biopolymer compositions) and coatings as well as methods and materials for making and using such compositions (e.g., biopolymer compositions) and coatings are provided.
Claims20
A composition comprising a first substrate and a material comprising a plurality of associated particles, wherein said plurality of associated particles comprises one or more cationic polymers and one or more anionic polymers, wherein said cationic polymers and said anionic polymers were combined in a polar solution and vigorously blended such that the viscosity or particle size of the mixed polymers was reduced after blending, and wherein said material is disposed on a surface of said first substrate.
A method for producing a composition, wherein said method comprises:
- vigorously blending one or more cationic polymers and one or more anionic polymers in a polar solution to produce a solution, such that the viscosity or particle size of the mixed polymers is reduced after blending;
- and
- coating a first substrate with said solution to provide a material disposed on a surface of said first substrate, wherein said material comprises a plurality of associated particles, and wherein said plurality of associated particles comprises said one or more cationic polymers and said one or more anionic polymers.
