US Patent 7161285 - Nanotube / Particle Impurity Film
http://www.freepatentsonline.com/7161285.pdf
Usually the use of nanotubes in electronic structures requires some degree of purification of the nanotubes so as to remove soot or other carbon particulates. This patent makes use of the impurities in a nanotube film to fill in gaps and increase mechanical film strength. Claim 1 reads:
1. A carbon nanotube (CNT) film, comprising: CNTs and particulate impurities, wherein said CNT film is formed as a stacked structure of a plurality of layers stacked in sequence, and the content ratio of said CNTs and said particulate impurities in each of said layers of said stacked structure is set independently of other layers.
