Mg/Al-LDH, Zn/Al-LDH, and Zn/Mg/Al-LDH were prepared using a coprecipitation method. Infrared emissivity values were acquired for the LDHs and leaves in the IR-2 Double Infrared Band. The test results revealed that the emissivities of the three LDH nanoparticles were similar to those of the leaves, and the emissivity of Zn/Mg/Al-LDH was lower than those of Mg/Al-LDH and Zn/Al-LDH in the 8-14 μm range. The reflectance spectra of the three LDHs were obtained using a UV-vis-NIR spectrophotometer. The similarit...
