Abstract:
A method of forming an article, the method comprising:adding a conductive polymer to a vessel; adding a crosslinkable polymer to a vessel; adding a crosslinking agent to the vessel; blending the conductive polymer, the crosslinkable polymer, water, and the crosslinking agent together to form a dispersion, each component of the dispersion, other than water, having a vapor pressure of about 400 mm Hg, or less, at a temperature of about 72Â° F.; applying a coating of the dispersion onto a substrate; and drying and curing the coating of the dispersion wherein: the dried and cured coating of the dispersion, when having a thickness of about 2.5 microns, is capable of permitting at least 95% transmission of visible light with a wavelength ranging from about 410 nanometers to about 700 nanometers; the surface resistivity of the dried and cured coating of the dispersion increases by about 9.5Ã—104 ohms/square, or less, after storage of the dried and cured coating of the dispersion for at least about 30 days in a humidity chamber at a temperature of about 25Â° C. and a relative humidity of about 80%, as compared to the surface resistivity of the dried and cured coating of the dispersion prior to placement in the humidity chamber; and the surface resistivity of the dried and cured coating of the dispersion increases by about 4.8Ã—105 ohms/square, or less, after storage of the dried and cured coating of the dispersion for at least about 30 days in a humidity of about 80%, as at a temperature of about 100Â° C. and a relative humidity of about 35%, as compared to the surface resistivity of the dried and cured coating of the dispersion prior to placement in the humidity chamber.
