The application of nano zinc oxide in invisible materials

Nano zinc oxide has a strong ability to absorb infrared rays, and the ratio of absorption rate to heat capacity is large. It can be used in infrared detectors and infrared sensors. Nano zinc oxide also has the characteristics of light weight, light color and strong wave absorption ability. Effectively absorb radar waves and attenuate them, using new wave-absorbing stealth materials.

1. The application of nano zinc oxide in stealth materials.

The quality of stealth materials directly affects the payload of weapons and equipment, the first-level speed of maneuverability, etc. Therefore, stealth materials are developing in the direction of "thin, light, wide and strong". Nano materials have excellent wave-absorbing characteristics, and also have the characteristics of thin thickness, light weight, bandwidth, and strong adaptability. Such as silicon nitride, silicon carbide, lead oxide, nano zinc oxide, and infrared light, radar waves. With the absorption capacity of a wide range of spectrum, it can be used for aircraft, spacecraft, satellites, missiles and radar stealth. Many countries in the world have studied and explored nano materials as a new generation of stealth materials.

At present, the world's military developed countries are studying nanocomposite materials covering the wavelength bands of centimeter wave, millimeter wave, infrared, and visible light. For infrared stealth coatings, the emissivity of the pigment is a key parameter that affects its stealth performance.
