  • Solar collector having selective film of improved stability to liquid water condensate
    Patent number: 4074706
    Abstract: Solar collector including a copper or copper alloy base and a selective solar heat energy-absorptive coating or film of improved stability to liquid water on the base. The selective film is characterized by having a solar absorptivity of 0.90 or higher, infrared emissivity no more than 0.20, and a stability such that its selectivity is not significantly reduced after contact with liquid water condensate over a prolonged, cumulative, non-continuous time in excess of 15,000 hours.
