Large specific surface area: The specific surface area of ​​nano zinc oxide is much larger than that of ordinary zinc oxide, which increases its chemical activity and reaction rate. High surface activity: Due to its extremely high specific surface area, nano zinc oxide exhibits stronger chemical activity and adsorption capacity. Piezoelectricity and fluorescence: Nano zinc oxide also exhibits excellent piezoelectricity and fluorescence, and can be used to make sensors and phosphors. UV shielding and absorption ability: Nano zinc oxide has strong absorption and scattering capabilities for ultraviolet rays, making it an ideal sunscreen and UV shielding material.
