Inkjet Printable Polypyrrole-ITO Conducting Inks

We have prepared organic conducting nanocomposite particles which utilize polypyrrole as conducting parts and small ITO particles as dispersants. The nanocomposite particles of polypyrrole and ITO represent potentially useful processable forms of polypyrrole, normally intractable conducting polymers. The conductivity of polypyrrole-ITO nanocomposite particles was two orders of magnitude higher than bulk polypyrrole under the same condition. We confirmed that these polypyrrole-ITO nanocomposite particles can be utilized as conducting inks due to their high colloidal stabilities.
