Abstract
A composite article comprises a porous, conductive layer disposed between a first liquid crystalline polymer layer and a second liquid crystalline polymer layer, wherein the porous conductive layer is impregnated with the first liquid crystalline polymer layer, the second liquid crystalline polymer layer or both liquid crystalline polymer layers. Each liquid crystalline polymer layers may be, independently, a single liquid crystalline polymer, a blend of liquid crystalline polymers, or a blend of non-liquid crystalline polymers and liquid crystalline polymers.
