具有可见光透明特性的动态机械响应红外热辐射调制器件
A Dynamic Mechanically Responsive Infrared Thermal Radiation Modulator with Visible Transparency
摘要
Abstract
Infrared thermal radiation modulators based on mechanically responsive materials offer advantages such as low cost,simple structure,and easy operation.Traditional infrared thermal radiation modulators based on me-chanical responses typically involve constructing metal films (such as gold,aluminum,copper,etc.) on an elastic substrate,which modulate infrared thermal radiation dynamically through the cracking and closing of the film layers.However,traditional dynamic infrared modulators are generally opaque in the visible light spectrum,which greatly limits their applications in fields like visible-infrared dual-band camouflage.In this study,ITO films were deposited on transparent elastic polymers that are transparent across a wide visible-infrared spectrum using a magnetron sputter-ing technique,creating thermal radiation modulators that are transparent in the visible light spectrum and highly re-flective in the infrared spectrum.Under mechanical stretching,the device exhibits an infrared reflectance range of 40％-77％ at the 10 μm and a visible light transmittance of over 82％ at 550 nm.关键词
