Abstract
A composite material comprising at least one polymer matrix. The polymer matrix comprises at least one inorganic load composed of a biphasic material that comprises at least one mesoporous substrate at least partially coated with carbon nanotubes. The composite material is remarkable in that the mesoporous substrate is composed of diatoms.

A composite material comprising at least one polymer matrix, said polymer matrix comprising at least one inorganic load composed of a biphasic material, the biphasic material comprising at least one mesoporous substrate at least partially coated with carbon nanotubes wherein the at least one mesoporous substrate is a mesoporous substrate with non-organized porosity;
- wherein the mesoporous substrate with non-organized porosity comprises silica from diatoms,
- wherein a composition of the mesoporous substrate with non-organized porosity in the composite material is comprised between 2% and 10%;
- and
- wherein the polymer matrix is composed of polymethylmethacrylate and/or at least one elastomer.
A synthetic process for a composite material, said synthetic process comprising a step of extrusion between at least one polymer matrix and at least one biphasic material, wherein the composite material comprises the at least one polymer matrix, the polymer matrix comprises at least one inorganic load composed of a biphasic material, the biphasic material comprising at least one mesoporous substrate at least partially coated with carbon nanotubes, and wherein the at least one mesoporous substrate is a mesoporous substrate with non-organized porosity;
