Key Features

UV shielding performance: The UV shielding rate of zinc oxide is as high as 98%, which can effectively block the damage of ultraviolet rays.

Antibacterial and antibacterial properties: Zinc oxide has excellent antibacterial and antibacterial properties, can effectively inhibit the growth of bacteria and fungi, and is widely used in antibacterial materials.

Photochemical effect: Zinc oxide has a photochemical effect, which can produce electrons and holes under light, and react with water or hydroxyl groups adsorbed on the surface to generate hydrogen and oxygen radicals and reactive oxygen species. These highly reactive groups can destroy organic matter and achieve the effect of sterilization and disinfection.

Biomedical applications: Excellent biocompatibility and antibacterial properties, nano-zinc oxide is used in the medical field for sterilization and disinfection, and can also be used as a drug carrier in the pharmaceutical industry.

Application Area

Enhanced thermal conductivity：

Nano-zinc oxide has a thermal conductivity of up to 25 W/(m·K) and is widely used in rubber tires, electronic devices and solar cells.

Rubber and plastic modification as rubber vulcanizing active agent：

Nano-zinc oxide can enhance wear resistance and aging resistance, and is used in the manufacture of anti-static tires and wear-resistant rubber products. Adding 40% nano-zinc oxide to polypropylene (PP) increases the thermal conductivity to 1.83W/(m·K) while maintaining the insulation and mechanical properties.

Coatings and sun protection：

Nano-zinc oxide has better shielding efficiency against ultraviolet (UV) than titanium dioxide and is widely used in sunscreens, cosmetics and architectural coatings.

Photocatalysis and Environmental governance：

Nano-zinc oxide decomposes organic matter under ultraviolet light and is used in sewage treatment, air purification and self-cleaning ceramics. It can degrade harmful gases such as formaldehyde and sulfides, and is used in marine coatings to achieve antibacterial and antifouling.

Solar cell：

The thermal diffusivity of nano-zinc oxide films increases with the increase of concentration. An appropriate concentration of zinc oxide precursor solution (such as 0.5 mol/L) can make the thermal conductivity of the film reach 4.69W/(m·K), reducing the efficiency attenuation of solar cells due to high temperature.

Piezoelectric and sensor: Using its piezoelectric effect, it is used in ultrasonic transducer, gas sensor and invisible material.   

Food and agriculture: As an antibacterial preservative to extend the shelf life of food, and as a plant growth regulator to increase crop yield.
