Abstract

A method of producing a structured composite material is described. A porous media is provided, an electrically conductive material is deposited on surfaces or within pores of the plurality of porous media particles, and an active material is deposited on the surfaces or within the pores of the plurality of porous media particles coated with the electrically conductive material to coalesce the plurality of porous media particles together and form the structured composite material.

First claim

What is claimed is:

1 . A method of manufacturing a structured composite material, the method comprising:
providing a porous graphene-based media; conformally depositing an electrically conductive material coating on the porous graphene-based media, wherein the electrically conductive material includes one or more of carbon allotropes, carbon alloys, semiconductors, or metals; depositing an active material on the electrically conductive material coating; and fusing the active material, the electrically conductive material coating, and the porous graphene-based media together to form the structured composite material.

2 . The method of claim 1 , wherein the porous graphene-based media is at least partially formed of silicon.

3 . The method of claim 1 , wherein the active material comprises sulfur, sulfur compounds, silicon, silicon compounds, boron, bromine, platinum, nickel, silver, molybdenum, iron, or any combination thereof.

4 . The method of claim 1 , wherein the active material is configured to form an alloy with the porous graphene-based media.

5 . The method of claim 1 , wherein the graphene-based media is defined by a morphological structure comprising a plurality of nanometer-scale pores interspersed within a web.

6 . The method of claim 1 , wherein the porous graphene-based media is defined by a mesoporous structure with a bi-modal pore size distribution.

7 . The method of claim 1 , further comprising:
prior to depositing the electrically conductive material coating on the porous graphene-based media, pre-treating the porous graphene-based media using a chemical etch or a mechanical size reduction process.

8 . The method of claim 1 , wherein the porous graphene-based media comprises a plurality of carbon nanoparticles each having a diameter less than approximately 10 microns.

9 . The method of claim 8 , further comprising:
providing a process input material; applying microwave or thermal energy to the process input material; separating the process input material into one or more separated components based on the applied microwave or thermal energy; and forming the plurality of carbon nanoparticles based on at least some of the one or more separated components.

10 . The method of claim 9 , wherein the process input material comprises carbon.

11 . The method of claim 1 , further comprising encapsulating the porous graphene-based media with a polymeric material.

12 . The method of claim 1 , wherein the porous graphene-based media has a surface area greater than approximately 50 m 2 /g.

13 . The method of claim 1 , wherein the porous graphene-based media has an electrical conductivity of greater than approximately 500 S/m.

14 . The method of claim 1 , wherein each pore in the porous graphene-based media has a dimension of less than approximately 50 nanometers (nm).

15 . The method of claim 1 , wherein the structured composite material is configured to produce elastomer compounds.
