Abstract:

A protective liner includes a base layer that can be affixed to an aircraft canopy or other substrate, a conductive polymeric interlayer positioned over the base layer, and a conductive top layer containing a reactive organic salt, or a hygroscopic salt, positioned over the conductive polymeric interlayer. The substrate can also be treated with a multilayer stack (including a substrate base coat layer, a metal layer positioned over the substrate base layer, a metal oxide layer positioned over the metal layer, and a tie layer positioned over the metal oxide layer). The protective liner can be affixed to a pretreated substrate by lamination or other means to form an enhanced, multilayer stack having beneficial properties.
