摘要：
Zirconium Boride (ZrB2) thin film exhibits excellent low infrared emissivity property, but the infrared emissivity in the mid-infrared waveband is still higher than that of traditional metal film. In this work, we reported Ag -ZrB2 nanocomposite film with low emissivity in the mid-infrared waveband by magnetron co-sputtering method. The effect of Ag content on properties of Ag-ZrB2 nanocomposite film were discussed in details. As the increase of Ag content, the infrared emissivity 83-5 mu m and 88-14 mu m decrease to 0.11 and 0.04 respectively. In addition, the reflectivity(R = 65%) of visible light is still lower than that of conventional metals. Consequently, the Ag-ZrB2 nanocomposite film shows low detectability in the infrared and visible wavebands, which is beneficial for infrared-visible compatible stealth. Meanwhile, ZrB2 matrix changes from hydrophilic to hydrophobic due to Ag segregation to the surface.
