Chinese and foreign researchers jointly developed stable self-cleaning coatings

It is understood that this scientific research result was jointly completed by six researchers from the University of London, Dalian University of Technology, and Imperial College of Technology.

The beautiful lotus leaves silt and does not stain.

Lu Yao said that many existing superhydrophobic surfaces are easily contaminated by oil and lose their self-cleaning properties.

The coating invented by Lu Yao's team is made of fluorinated titanium dioxide nanoparticles, which is extremely waterproof, but unlike other waterproof coatings, it can still function after being damaged or exposed to oily substances.

In addition, according to Song Jinlong, one of the researchers, a doctoral student at Dalian University of Technology, the previous superhydrophobic coatings have poor mechanical properties and poor bonding strength with the substrate, and are easily damaged during actual use.

"The self-cleaning paint we invented is fragile, and it is easy to remove it if it is accidentally sprayed on the body.

Song Jinlong said that the essence of this research is not to make the superhydrophobic surface so strong and wear-resistant, but to provide a unique idea-to transfer the "fragile" weakness in the superhydrophobic field to more mature adhesives.
