Phase Change Materials Nano VO2 Vanadium Dioxide Nanoparticles

Packing: 100g, 500g, 1kg, or according to customer's requirement.

Application: 

Vanadium dioxide Nanoparticles is a good phase change material, which can be doped with tungsten to prepare intelligent photochromic film materials.

Vanadium dioxide Nanoparticles is a oxide near 68 ℃ with phase change. It can be imagined that if the nano VO2 powder material with the function of phase change is compounded into the base material and supplemented with other fillers, a composite intelligent temperature control coating based on nanom VO2 can be made. When the surface of the object is coated with this coating, when the internal temperature is low, infrared light can enter the interior; When the temperature rises to the critical phase transition temperature, the phase transition occurs. At this time, the infrared light transmittance decreases and the internal temperature gradually decreases.When the temperature drops to a certain temperature, the nano VO2 will undergo an inverse phase transition and the infrared light transmittance will increase, so as to realize intelligent temperature control.

Nano vanadium dioxide film and ultrafine powder can be widely used in electrical and optical switching devices, solar control materials, optical disc dielectric materials, coatings, thermistors and other fields due to their unique phase change characteristics.
