Abstract

L'invention concerne un matériau composite de cohésion élevée, formé d'au moins un polymère et d'au moins un composé choisi parmi les oxydes minéraux, les silico-aluminates et le charbon actif, ledit matériau composite possédant : une taille médiane de particules d'au moins 100 μm, un volume poreux (Vd1 ), constitué par les pores de diamètre compris entre 3,6 et 1000 nm, d'au moins 0,2 cm3/g, une cohésion telle que son taux de particules de taille inférieure à 100 μm obtenu après une contrainte de pression d'air de 2 bars est inférieur à 1,5 %, de préférence égal à 0,0 %, en volume. Elle est également relative à un procédé de préparation de matériau composite. Elle concerne aussi l'utilisation de ce matériau composite comme support de liquide, support de catalyseur, additif ou pour la filtration liquide ou gazeuse, en particulier dans les filtres à cigarettes.
