  • Publication number: 20170266693
    Abstract: The present invention relates to a continuous roll-to-roll process for improving the water tolerance of bio-based polymers, in particular cellulose nanofibrils (CNF) films. Furthermore, the invention provides a method, which combines surface modification/functionalization for improving water stability and wet strength, UV/Ozone treatment, corona treatment or plasma activation for purifying and activating the surface and thus increasing the reaction efficiency, and further hydrophobization of the surface of CNF film.

  • Patent number: 9181653
    Abstract: The present invention provides a method for producing modified nanofibrillated cellulose characterized by bringing cellulosic material into a fiber suspension, adsorbing a cellulose derivative or polysaccharide or polysaccharide derivative onto fibers in said fiber suspension under special conditions and subjecting the obtained fiber suspension derivative to mechanical disintegration. A modified nanofibrillated cellulose obtainable by a method of the present invention is provided. Furthermore, the invention relates to the use of said modified nanofibrillated cellulose.
