基于阳极氧化工艺制备的无序超表面及其红外加热特性
Disordered Metasurface Prepared by Anodizing Process and Its Infrared Heating Characteristics
摘要
Abstract
The ability of a material to emit electromagnetic waves at a specific temperature depends on its surface spectral emissivity.At a fixed material composition,the thermal radiation spectrum of a surface can also be controlled by introducing surface micro/nano structures.In this study,Al/Al2O3 substrate with disordered micro/nano pores on the surface through an anode oxidation process.Afterwards,by depositing carbon nanoparticles(CNP)which have broadband NIR-absorption due to the porous structure,a disordered metasurface with high emissivity was obtained.Finite-difference time-domain(FDTD)calculations combined with experimental measurements show that its emissivity exceeds 0.95 benefited from the efficient capture of the incident light.Based on the high-emissivity infrared metasurface,efficient radiative heating by the developed disordered metasurface is further demonstrated.The results of this study provide new ideas for the design of infrared heating materials which can be promising for relevant applications.关键词
