Claim 19:
20. 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 first polymer comprising polyethylene terephthalate, and the precursor composition comprising:
a second polymer comprising polynorbornene-graft-poly(styrene))-block- (polynorbornene-graft-poly(ethylene oxide));
polyoctahedral silsesquioxane;
gold nanoparticles coated with 4-mercapto-phenol;
annealing the precursor composition;
irradiating the precursor composition with sub-millisecond light pulses so as to carbonize the the precursor composition, decompose the second polymer, and convert the polyoctahedral silsequioxane to silica to form a binder-free, mesoporous, composite structure, wherein the precursor composition is directly converted to the binder-free, mesoporous, graphitic multi-layer carbon composite without any addition of polymer or binder materials.
