The long-term objective of the Silvered Polymer Reflectors subtask within the SERI Solar Thermal Research Program is to develop silvered polymers that have a high specular reflectance, and to develop modifications of polymers that will protect the silver and maintain the reflectance in outdoor service environments for many years. The specific goals for FY 1985 were to achieve 90% specular reflectance within 7 mrad acceptance angle and to achieve ultraviolet radiation resistance that prevents detectable degradation during short-term accelerated laboratory tests. These goals set as intermediate checkpoints have been accomplished toward the long-term targets of a solar-weighted hemispherical reflectance of at least 90%, a specularity resulting in 90% of the solar flux being contained within a cone angle of 4-10 mrad, and a useful life of at least 5 years. This document reports the progress accomplished during FY 1985. We have used a dual approach by interacting with industrial fabricators to obtain and evaluate silver/polymer films, and by forming chemically modified silver/polymer mirrors at SERI to improve durability.
