http://www.freepatentsonline.com/7927567.html
The life expectancy of air filters is often limited dependent on the specific surface area of material used as an absorbent. This patent from Sharp teaches using carbon nanofibers to enhance the surface area and improve the life expectancy and increase the effectiveness of air filters. Claim 1 reads:
1. A porous filter, comprising:
a porous member having a plurality of holes; and
a nanostructure formed on an interior hole surface of said porous member.
