The invention relates to a composite material of high cohesion, formed of at least one polymer and at least one compound chosen from inorganic oxides, silico-aluminates and activated carbon, said composite material having: a median size of particles in number of at least 150 & mu m, - a pore volume (Vd1), consisting of the pores with a diameter of between 3.6 and 1000 nm, of at least 0.4 cm <3> / g, - a cohesion index ICN, equal to the ratio (median particle size in number after an air pressure constraint of 4 bar) / (median particle size in number without air pressure constraint (0 bar)), greater than 0.40 It also relates to a process for preparing a composite material It also relates to the use of this composite material as a liquid support, catalyst support, additive or for liquid or gas filtration, in particular in filters for cigarettes. |
