WEBSchiff base is a dynamic covalent reaction that forms imine bond linkage (C=N) between aldehyde and certain ketones with amino groups (primary amine, hydroxylamine, and hydrazine). Materials with an aldehyde functional group have been shown to form a highly stable Schiff base linkage with biopolymers having amine groups like CS.
