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.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A coating composition comprising 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. 
     
     
         2 . The composition of  claim 1 , wherein said cationic polymer is a polysaccharide. 
     
     
         3 . The composition of  claim 1 , wherein said cationic polymer is chitosan. 
     
     
         4 . The composition of  claim 1 , wherein said anionic polymer is carboxymethyl cellulose. 
     
     
         5 . The composition of  claim 1 , wherein said polar solution comprises water and formic acid adjusted to a pH of about 3-4.
