Patent ID: 8911821

Claim:
A method for forming a continuous interface between a plurality of sub-micrometer scale materials, the method comprising: providing the plurality of sub-micrometer scale materials, wherein the sub-micrometer scale materials are powders having a diameter smaller than 1 μm, and the plurality of sub-micrometer scale materials comprises nanometer scale carbon tubes, nanometer scale metal tubes, or nanometer scale oxide tubes; providing a metallo-organic compound; using xylene or toluene to dissolve the metallo-organic compound to form a solution; mixing the solution with the plurality of sub-micrometer scale materials so that the metallo-organic compound is uniformly dispersed on surfaces of the plurality of sub-micrometer scale materials; performing thermal decomposition and reduction of the metallo-organic compound to form a plurality of nanometer scale dot-shaped materials in-situ dispersed on the surface of the plurality of sub-micrometer scale materials wherein the plurality of nanometer scale dot-shaped materials and the plurality of sub-micrometer scale materials are heterogeneous; and melting the plurality of nanometer scale dot-shaped materials to connect the plurality of the sub-micrometer scale materials to each other and to form the continuous interface between the plurality of sub-micrometer scale materials.
