機能性添加剤としてのセルロースナノファイバ

抄録

Cellulose nanofibers (CNFs) are attracting as an eco-friendly new material. One of the functions of CNFs as an aqueous additive is rheology controlling with the network structure. CNFs can stabilize fine particles and form sprayable gels. CNFs has also emulsifying ability. CNFs can form oil in water emulsion (Pickering emulsion) by absorbing onto the surface of oil droplets thermodynamically. Third, CNFs can disperse hydrophobic particles in water. CNFs improve wettability and dispersibility of the particles by adsorbing its surface. CNFs are already applied to various fields, such as cosmetics, paints, inks, and ceramics with these unique properties.
