Abstract
An antistatic article including a substrate having a first surface, a sputtered conductive layer arranged on the first surface and having a thickness ranging from approximately 0.5 nanometers to approximately 10 nanometers, and an outer layer or a series of layers arranged atop the sputtered conductive layer, wherein, the antistatic article exhibits a surface resistivity of less than approximately 1012 ohms/square. A method of making an antistatic article includes pretreating a surface of the substrate, sputtering the conductive layer onto the surface to a thickness ranging from approximately 0.5 nanometers to approximately 10 nanometers, and sputtering the outer layer and one or more additional layers atop the conductive layer, wherein, the antistatic article exhibits a surface resistivity of less than approximately 1012 ohms/square.
