US Patent 7097906 - Single Walled Nanotubes and Diamond-like Carbon

High mechanical strength is one of the favorable properties of single walled carbon nanotubes. However, when formed in bulk, voids between the nanotubes may lead to defects that ultimately may reduce the strength of nanotube materials. This patent proposes a combinaton of nanotubes with another form of carbon with diamondlike structure in order to increase the strength.

Claim 1 reads:

1. A composition of matter, comprising: a pure carbon isotropic alloy having a plurality of allotropic forms of carbon, comprising single-walled carbon nanotubes and diamond-like carbon.
