Fudan University: The advanced functional coating developed by the research team of the Department of Materials Science has made progress in the application of major national projects

Recently, news came from China’s Mars exploration research team that the mars rover dust removal coating developed by the research team of the Advanced Coating Engineering Research Center of the Ministry of Education of Fudan University has been successfully applied on the Tianwen-1 rover Zhurong
.

On July 23, 2020, the "Tianwen-1" Mars probe developed by China was successfully launched from the Long March 5 Yaosi carrier rocket at the Wenchang Launch Center and successfully entered the scheduled orbit
.
The flight lasted half a year with a travel distance of over 450 million kilometers.
Tianwen-1 reached the orbit of Mars in February 2021, and landed on the surface of Mars on May 15th.
On the 22nd, the Zhurong rover safely left the landing platform and began to patrol the coating online.

As of the end of August, it had normally operated on the surface of Mars for 100 days and had travelled more than 1,000 meters in total, successfully completing the scheduled Martian surface exploration mission

In this Mars exploration mission, the power supply and distribution system of the Mars rover was developed by the General Department of the Fifth Aerospace Academy, and the Shanghai Space Power Research Institute implemented it
.
The scientific research team of Fudan University was commissioned by the Power Research Institute to successfully develop a dust-removing coating for glass cover sheets for use on the surface of solar cells on the "Zhurong" Mars rover
.
The dust removal coating is designed and constructed with a micro-nano structure, and the surface has good hydrophobic properties and resistance to the Martian environment, which can significantly reduce the force between Martian dust and the coating surface
.
The mars rover dust removal coating solution used in China's Mars exploration is the first international use.
Actual monitoring shows that the attenuation power of the rover solar cell caused by dust has dropped from 9%/month (NASA Opportunity) to about 2%/month , Solve the problem of the impact of Martian dust accumulation on the power generation efficiency of solar cells

The Advanced Coating Engineering Research Center of the Ministry of Education, which is responsible for the research and development of the dust-removing coatings for the Mars rover, was established in 2001.

In recent years, in addition to the aforementioned dust-removing coatings for the Mars rover, the advanced functional coatings developed by the coating center team have also made significant progress in major engineering applications in other countries
