20130087277 | METHOD FOR BONDING CONDUCTIVE MATERIAL - A method for bonding conductive materials by using composite adhesive made of carbon nanotubes and epoxy resin. Firstly, this composite adhesive is placed between the joining surfaces of the two conductive plates; thereafter an electric current enters from one conductive plate and passes through this composite adhesive, to the other conductive plate.
