US Patent 8129463 - Mixed DWNT/MWNT nanocomposites

This patent from Applied Nanotech is based on the finding that mixtures of multiwall carbon nanotubes and double walled carbon nanotubes can produce improved mechanical properties to nanocomposites at a lower cost than using single walled or double walled nanotubes alone. Claim 7 reads:

7. A method for making a carbon nanotube composite by varying an amount of carbon nanotubes to be added to the composite as a function of the diameters of the carbon nanotubes to increase the flexural strength and the flexural modulus of the carbon nanotube composite.
