Abstract

La présente invention concerne un procédé de préparation de fibres de cellulose fonctionnalisées, le procédé comprenant les étapes suivantes : a/ préparation d’une composition C1 comprenant de l’eau et des fibres de cellulose, b/ préparation d’une composition C2 comprenant de l’eau, un agent hydrophobe et un agent dispersant, c/ préparation d’une composition C3 en mélangeant les compositions C1 et C2 à une température T3 supérieure ou égale au point de fusion de l’agent hydrophobe, d/ fonctionnalisation des fibres de celluloses, par réaction entre les fibres de celluloses et l’agent hydrophobe, en présence de l’agent dispersant, à une température T4 supérieure ou égale au point de fusion de l’agent hydrophobe. La présente invention concerne également un procédé de préparation d’un film hydrophobe à partir de ces fibres de cellulose fonctionnalisées.
