A high-temperature-resistant nanofiber film simulating spectrum reflection characteristics of natural leaves

The risk of target exposure increases significantly with the advancement of detection technologies, especially in the visible and near-infrared spectral bands. Hence, there is an urgent need for a material with better environmental similarity. The primary background on the ground is green vegetation, necessitating the development of a material with a color similar to that of leaves. The high-temperature resistance CoAl₂O₄ Nanofiber Film (CNF) is conducted by electrospinning. The CNF is characterized by colors and spectral curves akin to vegetation in the visible light spectrum, and its spectral performance in the visible and near-infrared range is equivalent to that of CoAl₂O₄ Nanoparticle Powder (CNP). The color and reflection spectrum of CNF can be controlled through process parameters such as calcination temperature, enabling better environmental integration. Furthermore, CNF can be independently shaped without the involvement of a resin matrix, ensuring its high-temperature stability. This expands the application range of the material in high-temperature and complex environments.
