Scientists in Krasnoyarsk have developed a protective coating that significantly slows wood degradation caused by water, air exposure and ultraviolet radiation, as well as bacteria and fungi. The technology combines traditional linseed oil with aluminium oxide nanofibres and has already been introduced into industrial production, according to the website of the Federal Research Center "Krasnoyarsk Science Center of the Siberian Branch of the Russian Academy of Sciences."

The development was carried out at the Krasnoyarsk Scientific Centre of the Siberian Branch of the Russian Academy of Sciences. Linseed oil forms a polymer film when exposed to air, while aluminium oxide nanofibres reinforce this layer. The nanofibres are about 5,000 times thinner than a human hair and possess high mechanical strength. The researchers also developed a low-cost method for producing these nanofibres.

After application, the composite coating forms a dense protective film that limits moisture penetration, suppresses bacterial and fungal activity, and scatters ultraviolet radiation. This significantly extends the service life of wooden products, including those used outdoors.

The researchers noted that the nanofibres reduce drying time and help prevent cracking by stabilizing the polymer structure. According to the team, the technology offers an environmentally friendly solution for construction, furniture manufacturing and woodworking, demonstrating the practical application of advanced materials research.
