US Patent 7662300 - Method of preparing nanoporous material

http://www.freepatentsonline.com/7662300.html

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.
