Claims46
A method for forming a mesoporous material, the method comprising:
- providing an article comprising a layer of a polymer disposed on a substrate, wherein the polymer includes domains having a mesoscale structure and the polymer comprises a plurality of phases, wherein one of the phases forms the domains having the mesoscale structure;
- permeating the polymer disposed on the substrate with a solution comprising a precursor;
- reacting the precursor to form a deposit within the polymer, wherein the precursor is a metal oxide precursor and the deposit has a mesoscale structure corresponding to the domains;
- and
- removing the polymer from the article to form the mesoporous material comprising the deposit.
