Roll-to-roll method for producing polyaniline patterns on paper

High speed reel-to-reel manufacturing of electrically conductive polyaniline-dodecylbenzenesulfonic acid (PANI-DBSA) patterns directly onto paper substrate were investigated. A printing speed upto 100 meters per minute and line width down to 60 μm with a 60 cm wide paper web with a industrial scale pilot gravure printer was demonstrated. Additional measurements were made with printability tester using the conducting ink which consist of a PANI-DBSA in toluene solution. We illustrate what influence the concentration of the ink, printing speed and pressure at printing nip have on the conductivity of printed patterns
