Abstract

The invention provides liquid compositions comprising conductive carbon particles and/or carbon nanoparticles, a thickening agent, and a solvent. The carbon nanoparticles are preferably a mixture of graphite nanoplatelets and carbon nanotubes and the thickening agent is preferably a cellulose derivative. The liquid compositions can be used as ink to print highly conductive films that adhere to paper substrates.
