Chemical pre-treatments When producing cellulose nanofibrils (CNF), chemical pre-treatments can be applied to ease the fibrillation by introducing charged groups on the cellulose surface thus weakening the strong interfibrillar hydrogen bonds. This can result in a decrease in the energy needed to achieve adequate fibrillation level and additionally CNFs with functional groups are generated. When
