Messi Biology states that magnesium oxide, with its optical properties, stability, and environmental advantages, has become one of the key materials in snow camouflage nets. Some snow camouflage materials use magnesium oxide composite coatings, combined with titanium dioxide to adjust the reflection spectrum to achieve multi-band stealth. Combining nano-magnesium oxide with polyurethane has led to the development of lightweight, highly weather-resistant snow camouflage films. Future innovations in nanotechnology and composite materials are expected to further enhance its application potential in the field of multi-spectral stealth.
Magnesium oxide is a white powder with high reflectivity in the visible light band, which can effectively simulate the high-brightness white environment of snow, helping the camouflage net seamlessly blend with the surrounding snow scene in color. Magnesium oxide also exhibits good reflection characteristics in the near-infrared and shortwave infrared bands, which can reduce thermal radiation differences and avoid detection by infrared night vision devices or thermal imaging equipment. In addition, its scattering effect on ultraviolet light can also reduce the risk of exposure to ultraviolet detection.
Magnesium oxide is chemically stable, resistant to low temperatures and humidity. It is not easily decomposed or deteriorated in extreme environments such as severe cold and snow melting, ensuring the long-term performance of camouflage nets. Magnesium oxide can absorb or scatter ultraviolet rays, slowing down the photodegradation of polymer substrates such as PVC and polyester fibers, and extending the service life of camouflage nets. Incorporating magnesium oxide into the coating or fibers of camouflage nets can enhance the surface diffuse reflection effect, while improving the mechanical strength and wear resistance of the material.
The thermal conductivity of magnesium oxide can help regulate the temperature difference between the camouflage net and the snow, reducing thermal infrared signatures. Magnesium oxide itself has flame retardant properties, which can improve the fire resistance of camouflage nets. Compared with white pigments containing lead or titanates, magnesium oxide is more environmentally friendly and meets the military equipment requirements for low toxicity.
