The formed ITO powder was dispersed in 1-propanol and mixed with acrylic binder, surfactant, and initiator to get coating pastes. The coating pastes were coated on glass substrates by using a doctor-blade, and the resultant coatings were UV or thermal cured. The effects of the indium/tin ratio, calcination condition, coating paste composition, hydrolysis/condensation time, and coating method on sheet resistance and visible transmittance of the formed coatings were studied. In the extreme case, a coating with thickness of 1.5 μm sheet resistance of 199 Ω/sq and average visible transmittance of 92% could be prepared. The sheet resistance was increased in air environment because of entered moisture into the coating.
