Abstract:
A method of producing a composite material, comprising:providing a polymer matrix material;providing a nanostructured filler in powder form having a domain size of less than about 100 nanometers, wherein the nanostructured filler comprises a material selected from the group consisting of indium tin oxide, reduced indium tin oxide, dielectrics, ferrites, manganates; andmixing the nanostructured filler intimately with the matrix material at a filler loading selected to cause the composite material to have a resistivity that differs by more than 20% as compared with the resistivity exhibited by a composite material of similar composition with filler particles having a domain size of at least one micron;wherein the providing of the nanostructured filler includes applying a coating material to the exterior surface of the nanostructured filler and wherein the coating material comprises the matrix material.
