Combination of polymeric and metallic layers in a single device is becoming inevitable for applications in an increasing number of fields, including alternative energy. A basic product consisting in a metal-polymer (partially fluorinated) bilayer can be simply obtained by two steps. The first step of the process consists in surface modification of the polymer by plasma treatment, whose main effect is to increase the wettability. The increase of wettability by water is crucial for the second step of the process, which consists in aqueous based electroless deposition of metals. As revealed by cross cut and bending tests, adhesion between the metallic and polymeric layer is excellent. Given the suitable transparency and weathering resistance of Halar® ECTFE, the application of this process for production of solar concentrator mirrors is being considered. Light reflection properties and UV ageing were determined for this purpose.

Abstract

Combination of polymeric and metallic layers in a single device is becoming inevitable for applications in an increasing number of fields, including alternative energy. A basic product consisting in a metal-polymer (partially fluorinated) bilayer can be simply obtained by two steps. The first step of the process consists in surface modification of the polymer by plasma treatment, whose main effect is to increase the wettability. The increase of wettability by water is crucial for the second step of the process, which consists in aqueous based electroless deposition of metals. As revealed by cross cut and bending tests, adhesion between the metallic and polymeric layer is excellent. Given the suitable transparency and weathering resistance of Halar® ECTFE, the application of this process for production of solar concentrator mirrors is being considered. Light reflection properties and UV ageing were determined for this purpose.
