Abstract:
A process for forming a substantially transparent, electrically conductive film having a sheet resistance of less than 105 ohms/square comprising the steps of:(a) adding a nanocrystalline material to water, said nanocrystalline material comprising primary particles of metal or metal oxide having a substantially spherical shape; (b) mixing the nanocrystalline material and the water to form a substantially stable aqueous dispersion; (c) adding a film forming agent to the aqueous dispersion in an amount effective for the dispersion to provide a uniform, defect-free film when the dispersion is applied to a substrate, said film having a sheet resistance of less than 105 ohms/square; (d) adding a diluent to said aqueous dispersion to make a formulation; and (e) applying said formulation to a substrate.
