NOVELTY - The polyaniline (PANI)/carbon nano-composite conductive film comprises carbonaceous nanoparticles and PANI, where the film is provided by a surface resistivity of less than or equal to 1,000 Omega , a transparency of greater than or equal to 80% and a haze of less than or equal to 10%, and is adherable to a substrate (pass tape test, ASTM 3359D). The film has a thickness of less than or equal to 1200 nm. A concentration of carbonaceous nanoparticles in the conductive PANI/carbon nano-composite film is less than or equal to 3%. The conductive film is prepared by e.g. polymerizing aniline and carbonaceous nanoparticles by inverse emulsion polymerization conducted under sonication.    USE - The PANI/carbon nano-composite conductive film is useful for preparing commercial products such as touch screens, photovoltaic cells, flexible displays, gas sensors, dielectric devices, nanoelectronic devices, nano-composites, emitters, supercapacitors, fuel cells, sensors, actuators (e.g. electroactive paper actuators), and cathodes in several types of batteries such as lithium metal-polymer batteries.    ADVANTAGE - The conductive film meets the market requirements for surface resistance, transparency and haze, while having good adhesion properties.    DETAILED DESCRIPTION - The polyaniline (PANI)/carbon nano-composite conductive film comprises carbonaceous nanoparticles and PANI, where the film is provided by a surface resistivity of less than or equal to 1,000 Omega , a transparency of greater than or equal to 80% and a haze of less than or equal to 10%, and is adherable to a substrate (pass tape test, ASTM 3359D). The film has a thickness of less than or equal to 1200 nm. A concentration of carbonaceous nanoparticles in the conductive PANI/carbon nano-composite film is less than or equal to 3%. The conductive film is prepared by: polymerizing aniline and carbonaceous nanoparticles by inverse emulsion polymerization conducted under sonication, so as to obtain PANI/carbon nano-composites; de-doping the PANI/carbon nano-composites; re-doping the PANI/carbon nano-composites; and forming a film from the re-doped PANI/carbon nano-composites. The polymerizing step comprises forming a solution of aniline and a dopant in an organic solvent, and adding the polymerization initiator and the carbonaceous nanoparticles. INDEPENDENT CLAIMS are included for:    (1) a composition comprising the PANI/carbon nano-composite film adhered onto a substrate; and    (2) a process for preparing the PANI/carbon nano-composite film.    DESCRIPTION OF DRAWING(S) - The figures show flow diagrams of a polymerization step, a de-doping step and a re-doping step, respectively.
