US Patent 8110170 - Manufacturing conductive polymer-CNT composite


Supercritical fluids are substances in which distinct liquid or gas phases do not exist. This patent from SNU R+DB Foundation teaches a method of making carbon nanotube-polymer composites using supercritical fluids which may be applicable to the production of improved sensor and electrode materials. Claim 1 reads:

1. A method of manufacturing a conductive polymer-carbon nanotube composite, comprising the steps of:

introducing a monomer of a conductive polymer into an open-ended carbon nanotube using a supercritical fluid; and

polymerizing the monomer to fill the carbon nanotube with the conductive polymer.
