Abstract

See full text

Conductive coating compositions and methods of preparation and application thereof are provided, whereby a mixture of conductive polymer encapsulated particles and non-encapsulated particles are employed to provide a conductive surface coating with controllable viscosity and conductivity. The particles may be filler and/or pigment particles such as calcium carbonate or clay, a portion of which are coated with a conductive polymer such as polypyrrole. Encapsulated particles are prepared and filtered, mixed with non-encapsulated particles, and subsequently combined with a binder for application to a surface or substrate such as paper. A dispersant may be included to obtain a suitable viscosity of the mixture prior to application. The relative concentrations of the encapsulated and non-encapsulated particles may be selected to tailor the resulting conductivity of the coating.
