Abstract

Thermal cameras detect the infrared radiation emitted by objects, which is related to their temperature. Even if an object is coated with nano silica, it will still emit thermal radiation based on its temperature, and this radiation can be detected by a thermal camera. While nano silica coatings or materials can have specific properties, such as heat resistance or thermal insulation, they do not provide a means for complete invisibility on a thermal camera. The visibility of an object on a thermal camera primarily depends on the temperature contrast between the object and its surroundings. It's important to note that materials that have low thermal conductivity or specific thermal properties can affect the distribution of heat and temperature gradients on an object's surface. This can potentially impact the thermal signature observed on a thermal camera, but it does not result in complete invisibility. This study developed a nano-silica treatment technique through thermal fusion techniques, which resulted in the complete disappearance of the object when covered with heat-treated silica.
