US Patent 7105596 - Polymer Composite with at least a Million Single Walled Nanotubes

Due to multiple continuation filings a series of broad single walled nanotube patents with early priority dates have been issuing recently from Rice University (i.e. Smalley et al.) This patent claims all single walled nanotube polymer composites including more than a million nanotubes. Claim 1 reads:

1. A composite material comprising: (a) a matrix, wherein said matrix comprises a polymer; and (b) a single-wall carbon nanotube material embedded within said matrix, wherein said single-wall carbon nanotube material comprises fibers of greater than 10.sup.6 single-wall carbon nanotubes.
