The present disclosure provides aqueous binders that address challenges associated with simple linear polymer binders. In some embodiments, a binder includes Lewis acid sites and Lewis base sites that chemically interact. Different species, such as two different types of polymers or a linear polymer and particle (e.g., made of a different polymer), can be used. A first species may have only Lewis acid sites in (e.g., on) it and a second species may have only Lewis base sites in (e.g., on) it. In some embodiments, linear polymer comprising Lewis base sites (e.g., in its backbone) and polymer particles comprising Lewis acid sites are used to form a supramolecular binder where the Lewis acid sites and the Lewis base sites are chemically interacting. In some embodiments, cationic and anionic polymers are used to form a binder with chemically interacting Lewis acid sites and Lewis base sites.
