Solid state electrically conductive laminate
First Claim
1. A unitary, composite, laminated article of manufacture comprising:
- (A) an electrically insulating top layer having an inner surface and an outer surface;
(B) a first barrier layer of polymeric material having a water vapor transmission rate (ASTME
96) not exceeding about 0.5 g/100 sq.in./24 hr/mil at 37.8°
C., wherein said first barrier layer substantially covers said inner surface of said top layer;
(C) an electrically insulating bottom layer having an inner surface and outer surface;
(D) a second barrier layer of polymeric material having a water vapor transmission rate (ASTME
96) not exceeding about 0.5 g/100 sq.in./24 hr/mil at 37.8°
C., wherein said second barrier layer substantially covers said inner surface of said bottom layer;
(E) a substantially continuous, electrically conductive layer of substantially uniform thickness between said first and second barrier layers, wherein said electrically conductive layer is comprised mainly of carbon and is capable of emitting electromagnetic radiation when an electric current is passed therethrough;
(F) electrical conductor means in contact with said electrically conductive layer;
wherein said top layer and said bottom layer have edges, which are sealed together to thereby form an enclosed laminate containing an electrically conductive layer having stable resistivity.

Abstract
A unitary, composite laminated article comprises an electrically insulating top layer and an electrically insulating bottom layer. Applied to the inner surfaces of each of these layers is a barrier layer substantially impermeable to moisture and water vapor. A substantially continuous electrically conductive layer of substantially uniform thickness is interposed between the barrier layers. The electrically conductive layer is comprised mainly of carbon and is capable of emitting electromagnetic radiation when an electric current is passed therethrough. In contact with the electrically conductive layer is electrical conductor means. The top layer and bottom layer are sealed together to thereby form an enclosed laminate. The electrically conductive layer exhibits very stable resistivity. The use of the article as a radiant heating device and a method for its manufacture are provided. The device is especially useful for personal comfort heating and as a heat source in commercial, residential and industrial establishments.
