in this study, far infrared low-emissive coatings have been prepared using a spin-coated 2-mu m layer of commercial inorganic binder under a spin-coat produced from nanosized silver solution, resulting in Ag films of thicknesses between 0.1 and 1 mu m. The bilayer coatings were baked at various temperatures for 30 min in air. The 1-mu m Ag film baked at 150 degrees C exhibited an extremely low emissivity, of 0.04 in the far infrared range wavelengths of 8 to 14 mu m. In addition, this nano-silver paint showed good adhesive strength and the capability to withstand a neutral salt test. (C) 2007 Elsevier B.V. All rights reserved.
