US Patent 7662300 - Method of preparing nanoporous material

Nanoporous materials have been suggested to improve the efficiency of energy storage and conversion devices such as supercapacitors and fuel cells. This patent from Samsung teaches a method for controlling the size and uniformity of the nanopores in such materials. Claim 1 reads:

1. A method for preparing a porous material using nanostructures, the method comprising the steps of:

(a) producing nanostructures using a porous template;

(b) dispersing the nanostructures in a source or a precursor material for a porous material;

(c) aligning the nanostructures in a particular direction; and

(d) removing the nanostructures by etching.
