The World’s First! Three Forms of CNF

Cellulose nano-fiber (hereinafter CNF) is plant fiber (pulp) that is finely fibrillated (hereinafter nano-fibrillation) to the nano-order (one millionth of a millimeter) making it about one twenty thousandths of the thickness of human hair.
CNF is a superior material that is transparent, light and strong, resistant to changing shape and has a powerful thickening effect. It can be expected to be used in many fields.

CNF production technology: Nano-fibrillation technology

Oji’s Unique Nano-fibrillation Technology

CNF is manufactured by nano-fibrillating pulp. The phosphate esterification method we established introduces a phosphate group, which is an ionic functional group, to the surface of the CNF and, by raising the level of electrostatic repulsion among CNF, makes nano-fibrillation easier to achieve. With this technology, the manufacturing of high quality (high transparency, high viscosity) CNF is possible.

Slurry

World’s Highest Level of Transparency, Ultra-high Viscosity and Dispersibility

Our CNF is a completely nano-fibrillated fiber with superior transparency, ultra-high viscosity and dispersibility.

Wet powder

Superior Dispersibility and High Viscosity (Thickening Effect)

Wet powder CNF can be dispersed as a regular slurry with light mixing.

Continuous Transparent Sheet

Same Level of Transparency as Glass

Possible applications

We are advancing the development of a range of applications that effectively utilize the various features of CNF.
