Abstract
Additives to organic conducting polymers are described which enhance adhesion and resolution of printed films while retaining adequate electrical conductivity. The conductive polymer films are useful in printing conductive portions of thin film transistors such as sources and drains. Additives include surfactants, second macromolecules, plasticizers, and excess sulfonic acids.
