Abstract
The present invention concerns a process for preparing a composite of porous material/compound/hybrid organic-inorganic material having a 2:1 lamellar structure, said hybrid material having the following general formula I:Na[(Mg)(Al(RSi))O(OH)]  (I)whereinx is a number such that 0≤x<1.2 andR represents a C-Calkyl group, an aryl group, a (C-Calkyl)aryl group or an O—(C-Calkyl) group, it being possible for the alkyl group to be substituted with a group chosen from a phenyl, vinyl, aminopropyl or mercaptopropyl group,and said compound being chosen from the group constituted of at least one active substance and at least one microorganism and mixtures thereof the process comprising:a) the step of sol-gel synthesis of the hybrid organic-inorganic material having a 2:1 lamellar structure in the presence of the compound and of the porous material saturated with the compound;b) the recovery of the composite. It also concerns a composite obtainable by means of this process, a composition comprising it and its use in particular for the fertilization of plants.
