Abstract: The invention describes a method of forming aqueous lignin-epoxy hybrid nanoparticles with switchable surface characteristics. The invention is applicable to production of technical adhesives and covalent surface modification of lignin nanoparticles under harsh reaction conditions. Further, in terms of the covalent functionalization of lignin nanoparticles (LNPs), this invention presents the covalent cationization of LNPs by means of attached quaternary ammonium groups.
