US Patent 7740825 - Formation of CNT aggregate


Most material applications of carbon nanotube include adding the nanotubes to a composite polymer or metal matrix which can enhance the electrical or thermal properties of the matrix but do not provide the maximum benefit of the CNT properties. This patent from Stella Chemifa Corp. teaches a way to form pure nanotube aggregates using fluorine. Claim 1 reads:

1. A method for forming a carbon nanotube aggregate, comprising

(1) modifying multiple carbon nanotubes with fluorine, and

(2) sintering the multiple carbon nanotubes modified with fluorine.
