Abstract

We have prepared organic conducting nanocomposites of polypyrrole in the conductive portion, and indium tin oxide (ITO) or zirconia (ZrO2) nanoparticles as dispersants. The polypyrrole-inorganic oxide nanoink successfully achieved stable colloidal dispersion of polypyrrole in water, which usually aggregate in aqueous liquids. The polypyrrole-ITO nanocomposites exhibited up to a conductivity of 15 S/cm, while that of the polypyrrole-ZrO2 was 2.3 S/cm. Applying the polypyrrole-inorganic oxide to an olfactory receptor chip, we measured the resistance during ammonia injection as an odorant, in order to explore its potential as an olfactory sensor.
