| 摘要 |
The invention relates to a highly cohesive composite material, formed of at least one polymer and at least one compound chosen from mineral oxides, silicoaluminates and activated carbon, said composite material having: - a number median particle size of at least 150 μm, - a pore volume (Vd1), constituted of pores of diameter between 3,6 and 1000 μm, of at least 0,4 cm/g, and - a cohesion index CI, equal to the ratio (number median particle size after an air pressure stress of 4 bar)/(number median panicle size without air pressure stress (0 bar)), greater than 0,40. It also relates to a method for preparing the 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 cigarette filters. |
