Title
(EN) PROCESS FOR HYDROPHOBIC MODIFICATION OF NANOCELLULOSE DURING MANUFACTURING
(FR) PROCESSUS DE MODIFICATION HYDROPHOBE DE NANOCELLULOSE PENDANT LA FABRICATION
Abstract
(EN)
Modified nanocellulose particle include a nanocellulose particle, a binder coating the particle, and an alkyl amine affixed to the binder coating. A method of modifying nanocellulose particles includes adding a binder and a hydrophobizing agent to a slurry of nanocellulose particles in water, modifying the nanocellulose particles with the binder and hydrophobizing agent, and collecting the modified nanocellulose particles.
(FR)
L’invention concerne une particule de nanocellulose modifiée comprenant une particule de nanocellulose, un liant recouvrant la particule, et une alkylamine fixée au revêtement à base de liant. Un procédé de modification de particules de nanocellulose consiste à ajouter un liant et un agent d'hydrophobisation à une suspension de particules de nanocellulose dans de l'eau, à modifier les particules de nanocellulose à l'aide du liant et de l'agent d'hydrophobisation, et à collecter les particules de nanocellulose modifiées.
