Abstract:
1. A method for making a structured ceramic material having nano-ordered structure in at least a portion thereof and in which particles of at least one metal are disposed, comprising: a) providing an inorganic block copolymer containing at least one inorganic-based block, wherein the inorganic block copolymer comprises an ordered structure and at least one of the group consisting of polycarborane, polynorbornene and polynorbornene-decaborane; b) providing a plurality of metallic particles that have an affinity for at least one block of said block copolymer, said metallic particles being selected from the group consisting of metal particles that have an affinity for at least one block of said block copolymer and metal particles coated with an agent that has an affinity for at least one block of said block copolymer; c) dissolving the block copolymer in a solvent; d) contacting said copolymer with said metallic particles to obtain an inorganic block copolymer with metallic particles disposed therein; e) evaporating the solvent to cause self-assembly of the block copolymer; and f) pyrolyzing said inorganic block copolymer with metallic particles disposed therein.
