摘要： A method for preparing a composition including mineral particles functionalized by at least one organic group and having a specific surface defined according to the BET method greater than 500 m2/g, involves: —choosing a phyllosilicate composition, including mineral particles having a thickness of less than 100 nm, a largest dimension of less than 10 μm and belonging to the family of lamellar silicates; —choosing at least one functionalizing agent, from the group formed from the oxysilanes and oxygermanes having at least one organic group, —bringing the phyllosilicate composition into contact with a functionalizing solution including the functionalizing agent, so as to obtain a phyllosilicate composition including mineral particles functionalized by the organic group, while choosing the organic group from the group formed from the cationic heteroaryl groups, the quaternary ammonium groups and the salts of same. The phyllosilicate composition obtained by the method is also described.

摘要： A composition comprising synthetic mineral particles, such as silicate or phyllosilicate mineral particles, is presented. The composition can be prepared by a process in which a hydrogel precursor of the synthetic mineral particles is produced by a coprecipitation reaction between at least one compound comprising silicon, such as sodium metasilicate, and at least one compound comprising at least one metal element, such as a dicarboxylate salt of the formula M(R1—COO)2, wherein R1 is H or an alkyl group having 1 to 4 carbon atoms. The coprecipitation reaction also takes place in the presence of at least one carboxylate salt of formula R2—COOM′ wherein M′ is Na or K, and R2 is H or an alkyl group having 1 to 4 carbon atoms.
