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.
