Abstract
Compositions and methods of producing paper-based materials are disclosed. In general, the techniques utilize an amine-containing polymer, such as chitosan, to functionalize one or more components of a mixture used to form materials such as paper-based materials. Such components can include the fibers of a pulp and/or filler particles. In one instance, either the pulp or the filler particles are functionalized, but not both. Such functionalization can improve the qualifies of a paper-based material relative to when such functionalization is not utilized. Techniques and compositions are also described to further improve the qualities of a paper material by utilizing a complementary polymer which can couple with the amine-containing polymer.
