Claim 18:
19. A method of forming a binder-free, mesoporous, graphitic multi-layer carbon composite structure, the method comprising:
disposing a precursor composition on a substrate, which comprises a metal, and the precursor composition comprises:
a porogen being a polymer comprising polynorbornene-graft-poly(styrene))-block- (polynorbornene-graft- poly(ethylene oxide));
phenol formaldehyde resin; and
at least one of gold nanoparticles coated with 4-mercapto-phenol or iron/iron oxide nanoparticles coated with 4-hydroxybenzoic acid;
irradiating the disposed precursor composition with sub-millisecond light pulses so as to carbonize the precursor composition, decompose the porogen, and convert the phenol formaldehyde resin to a graphitic material to form a binder-free, mesoporous, graphitic multi-layer carbon composite structure,
wherein the graphitic material is generated during irradiation, and the precursor composition is directly converted to the binder-free, mesoporous, graphitic multi-layer carbon composite without any addition of, polymer, or binder materials.
