Inventing self-cleaning paint

British and Chinese scientists developed a new self-cleaning paint that has high applicability on many materials and still works effectively even when scratched.

New type of self-healing paint

New paint can clean itself when damaged or soaked in oil

According to a study published in the March 5 issue of Science, scientists say the completely impervious paint made from titanium dioxide nanoparticles . Unlike other water-proof coatings, this new invention can still clean itself even if it is damaged or soaked in oil.

" The biggest challenge for self-cleaning surfaces is to find ways to help them withstand the elements of daily damage, " said Clair Carmalt, professor of inorganic chemistry at the University of London (UCL). study, talk.

Due to its high durability, this coating can be widely used in many areas from cloth, paper, glass to steel . In addition, scientists also use the available materials to increase the usability of the product.

" Water resistance helps the materials clean themselves, because the water forms droplets that roll on the surface, like mini vacuum cleaners, that carry dirt, viruses and bacteria, " the author studied. Yao Lu of UCL said.

Depending on the surface material, the scientists use different coating technologies such as the bolt gun for glass and steel surfaces, the dipped coating method for cotton, wool surfaces and the paper spraying method. In addition to UCL, the Royal Academy of London and Dalian Technology University, China also participated in the study.
