技術說明

Cellulose nanofiber prepared by TEMPO-oxidation (known technology) is modified by amine with long alkyl chain (octadecyl, oleyl, dodecyl, and so on) by amidation reaction with moderate binding ratio (20-90 % of carboxyl group in cellulose nanofiber). The films of modified cellulose nanofibers can be highly transparent and self-standing. The films exhibit the hydrophobicity and the oil-repellency. Therefore, the films can be used for the self-cleaning and anti-fingerprint films and coating.
