Abstract
A method is provided for decontaminating a surface that is susceptible to contamination by a contaminant by applying to the surface a coating which produces a decontaminating agent for the contaminant in response to a signal, connecting the electroactive coating to a source of a signal, and when the surface is contaminated, applying the signal to the electroactive coating, thereby producing one or more decontaminating agents which neutralize or destroy the contaminant. Coatings for practicing the method and articles that have been protected by the novel coatings are also provided.

16. A method of decontaminating a surface that is susceptible to contamination with a contaminant, the method comprising:
-
applying to the surface a coating which produces a decontaminating agent for the contaminant when an electrical potential is applied to the coating;
connecting the electroactive coating to a source of an electrical potential; and
when the surface is contaminated,applying an electrical potential to the electroactive coating, thereby producing the decontaminating agent and destroying the contaminant. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
