The invention relates to a composite material including nanotubes of a chemical element selected from the compounds of the elements of columns IIIa, IVa and Va of the periodic table, dispersed in a polymer matrix including (a) at least one fluorinated homo- or copolymer and (b) at least one fluorinated homo- or copolymer grafted with at least one carboxylic polar function. The invention also relates to the use of the composite material and to the use of at least one fluorinated homo- or copolymer grafted with at least one carboxylic polar function for increasing the tensile strength of a composite material containing the above nanotubes dispersed in a fluorinated polymer matrix.
