Brief introduction of nano diamond pwoder in nano film:

Researcher Tang Yongbing's team from the Functional Thin Film Materials Research Center of the Shenzhen Institutes of Advanced Technology, Chinese Academy of Sciences, and Professor Zhang Wenjun from the City University of Hong Kong, have developed an ultra-thin diamond nano film with high self-transmittance from ultraviolet to infrared bands, and has anti-fog and underwater self-transmission properties. The series of properties provide a new strategy for surface protection in important fields such as optical lenses, marine precision instruments, high-definition surveillance, and infrared sensors.
Tang Yongbing's team successfully produced a high-density nano diamond film with a thickness of only 45nm through the self-assembled crystal-planting vapor deposition method independently developed. The coated quartz glass has a light transmittance of up to 90% in the ultraviolet and visible light bands, and the light transmittance under water up to 98%, close to uncoated quartz glass. The nano diamond film has an anti-reflection effect in the infrared band, and the light transmittance of the coated quartz glass is as high as 85%, which is 10% higher than that of the uncoated quartz glass.

Further studies have found that the nano-film after surface treatment has super-hydrophilic and underwater super-oleophilic properties, so that the coated glass still has the function of transparency and anti-fog in the environment of drastic changes in steam and temperature, and it can resist the adhesion of oil stains underwater, to achieve underwater self-cleaning function. In addition, this kind of ultrathin diamond nano film has excellent anti-wear performance. After the high-speed moving sand particles hit the surface of the diamond nano film, its surface morphology and transmittance rate remain basically unchanged. It is also found that the coated quartz glass has an ultra-low friction coefficient and self-lubricating function, and the friction coefficient is 1/3 lower than that without coating.

At present, the super-thin diamond nano film with wide band and high light transmittance can be prepared on various commercial substrate materials have good application prospects such as in semiconductor, quartz, glass, etc..
