ABSTRACT:
Highly weather and corrosion resistant flexible reflective films for solar energy applications and lighting reflectors are formed by vapor-depositing silver onto a flexible support sheet, e.g., biaxially oriented polyester film and adherently bonding a protective fluorocarbon film, e.g., poly(vinyl fluoride), poly(vinylidine fluoride), or poly(tetrafluoroethylene), to the surface of the silver distal to the flexible support sheet with a layer of adhesive. Fluorocarbon film is highly optically transmissive to visible, ultraviolet, and/or near infra-red light between about 300-2,500 nanometers, stable to ultraviolet light, impervious to moisture, non-hygroscopic, scratch resistant, and easy to keep clean. The adhesive is highly optically transmissive to light between about 300-2,500 nanometers and stable to ultraviolet light. Chemical corrosion inhibitors and UV absorbers incorporated into the flexible reflective film can increase its resistance to corrosion and degradation by ultraviolet light.
