Title (EN) PROCESS FOR THE PRODUCTION OF GEL-BASED COMPOSITE MATERIALS
(FR) PROCÉDÉ POUR LA PRODUCTION DE MATÉRIAUX COMPOSITES À BASE DE GEL
Abstract: front page image
(EN)A process for the production of composite materials comprising nano-fibrillar cellulose gels, by providing cellulose fibres and at least one filler and/or pigment, combining the cellulose fibres and the at least one filler and/or pigment, fibrillating the cellulose fibres in the presence of the at least one filler and/or pigment until a gel is formed, subsequently providing at least one further filler and/or pigment and combining the gel with the at least one further filler and/or pigment.
(FR)L'invention porte sur un procédé pour la production de matériaux composites comprenant des gels de cellulose nanofibrillaire, par l'utilisation de fibres de cellulose et d'au moins une charge et/ou au moins un pigment, la combinaison des fibres de cellulose et de ladite ou desdites charges et/ou dudit ou desdits pigments, la fibrillation des fibres de cellulose en présence de ladite ou desdites charges et/ou dudit ou desdits pigments jusqu'à ce qu'un gel se forme, par la suite l'utilisation d'au moins une autre charge et/ou d'au moins un autre pigment et la combinaison du gel avec ladite ou lesdites autres charges et/ou ledit ou lesdits autres pigments.
