The invention relates to a nanocomposite material on the basis of a clay having a layered structure and a cation exchange capacity of from 30 to 250 milliequivalents per 100 gram, a polymeric matrix and a block copolymer or a graft copolymer, which block copolymer or graft copolymer comprises one or more first structural units (A), which are compatible with the clay, and one or more second structural units (B), which are compatible with the polymeric matrix.
Cette invention a trait à un matériau nanocomposite à base d'argile à structure en couches possédant une capacité d'échange cationique comprise entre 30 et 250 milliéquivalents par 100 grammes, de matrice polymère et de copolymère séquencé ou de copolymère greffé. Le copolymère séquencé ou le copolymère greffé comporte un ou plusieurs premiers motifs structuraux (A), compatibles avec l'argile, et un ou plusieurs seconds motifs structuraux (B), compatibles avec la matrice polymère.
