Mesoporous nanocrystalline film architecture for capacitive storage devices

A method for producing a nanostructured, mesoporous material construct, comprising:

• synthesizing a plurality of metal oxide nanocrystals;
• forming a solution of nanocrystals, at least one polymer and a solvent;
• disposing said solution on a substrate to form a polymer tem plated film;
• evaporating the solvent from the tem plated film;
• and
• thermally decomposing the polymer templated film to remove said polymer template and produce a mesoporous nanostructured construct.

A method for producing a capacitive storage device, comprising:

• co-dissolving a metal oxide molecular precursor and a polymer in a solvent to produce a solution;
• disposing said solution on substrate to form a film;
• evaporating the solvent from the film;
• and
• thermally processing the film to remove the polymer and crystallize the film to provide a mesoporous nanocrystalline film on said substrate.

A method for producing a nanostructured material construct, comprising:

• mixing at least one polymer, at least one solvent and at least one metal salt to produce a sol-gel precursor solution;
• forming a gel from the sol-gel precursor solution on a substrate;
• evaporating the solvent from the gel;
• and
• thermally processing the gel to remove the polymer and crystallize the gel to provide a porous nanostructured material construct on said substrate.
