Progress at Agfa with PEDOT: PSS printing

Progress at Agfa is leading to flexographic, offset and other inks suitable for high speed and high resolution applications and for ink jet, said Louis Bollens at the recent Conductive Polymers conference in Brussels, Belgium. PEDOT: PSS is used. Its Orgacon screen printing organic ink is used to make thinner cellphone keyboards by co-moulding. PSS means polystyrenesulfonic acid which adds molecular tendrils to the PEDOT molecule giving gels with up to 95% water.
