Synthesis and Infrared Stealth Property of Ordered Mesoporous Carbon–Aluminum-Doped Zinc Oxide Composites

Ordered mesoporous carbon–aluminum-doped zinc oxide (C-AZO) composites were prepared by the solvent-evaporation induced self-assembly method (EISA). The mesoporous structure was evaluated by small-angle X-ray scattering (SAXS), transmission electron microscopy (TEM), and N2 adsorption–desorption. The results showed that the composites had uniform pore size and high surface area. Textural characteristics of the nanocomposites were affected by the carbonization temperature. The specific area and pore volume increased upon increasing the calcination temperature, while the pore diameter decreased. The infrared emissivity value (8–14 μm) of ordered mesoporous C-AZO was measured by an IR-2 Infrared Emissometer. The results showed that infrared emissivity was as low as 0.39, which exhibited outstanding performance of infrared stealth.
