Cellulose nanofibrils (CNF) is a renewable material, which has a high aspect ratio, large specific surface area and high mechanical strength. However, since the hydrophilicity of CNF limits the expansion of the application, CNF is required to be hydrophobized in some cases. In this study, silylation of CNF under an aqueous system was investigated in order to increase the hydrophobicity of CNF. Methyltrimethoxysilane (MTMS) was selected as a silylating agent. The hydrophobicity of CNF was greater under acidic conditions and at a 1:1 oven-dried weight ratio of CNF and MTMS. The excessive amount of MTMS did not enhance the hydrophobicity of CNF. Curing treatment should be followed by the silylation of CNF. The hydrophobization of CNF could be carried out successfully under an aqueous system without an organic solvent.
