Fuente: WIPO "tomato" A coating formulation and an adhesive formulation includes charged cellulosic fibrils, wherein the charged cellulosic fibrils include carboxyl functional groups. The coating formulation can include pigments to define a paint formulation. The charged cellulosic fibrils can include nitro-oxidation-process-derived charged cellulosic fibrils. The charged cellulosic fibrils include nanocellulose (NC), cellulose nanocrystals (CNC), cellulose nanofibrils (CNF), cellulose microfibrils (CMF), or lignin-containing cellulose nanofibers (LCNFs). The charged cellulose fibrils can define a three-dimensional network that breaks down when a shear force is applied. The carboxylate functional groups can interact electrostatically and chemically with a surface of a substrate when applied to the substrate.
