Specific Properties of Metallic Nano-Layers and Their Application in Active Packaging Systems
Original language description
The aim of our work was to test electrical and optical properties (especially surface resistivity and optical absorbance) of laboratory prepared Al susceptors and to determine the relationships between them and to find the optimum thickness of metallization from the point of view of maximum microwave energy absorption in the film. Set of Al layers of varying thickness (from just about 3 to 30 nm) were deposited onto PET films by vacuum evaporation. Prepared susceptors have non-uniform, perforated structure as resulted from microscopic and AFM observation. DC surface resistivity was measured by classical four point method. Optical absorbance of susceptors was measured by UV/VIS Spectrometer Perkin Elmer Lambda 11 at the wave length 626 nm. A set of susceptors was tested in measurement waveguide at the frequency 2.45 GHz and the applied microwave power of 1.8 mW. The maximum microwave energy absorption at 2.45 GHz was found to occur in susceptor of optical absorbance of about 0.22.
