Goal and objectives of the project

Development of an anti-friction, corrosion protection hydrophobic coating system based on polymers and monolayer and multilayer amphiphilic organic thin films on the polymer surface by Langmuir-Blodgett (LB), spin-coating and self-arrange methods.

Main results

The coating systems of polyurethane/oligomethylsiloxane, olyurethane/perfluorohexadecan, polyurethane/behenic acid and polyurethane/stearic acid have been successfully fabricated by spin-coating method and polyurethane/2.4-heneicosanedion by the Langmuir–Blodgett method on steel substrates. The evaluation of the frictional, hydrophobic and corrosion resistance properties of coating systems showed that the thin films of perfluorohexadecan, 2.4-heneicosanedion and behenic acid significantly improved  the corrosion resistance and hydrophobicity of polyurethane coating. The highest contact angle was obtained with the perfluorohexadecan film, reaching 116o.

Novelty and actuality and scientific meaningfulness of the results

Anti-friction, corrosion protection hydrophobic coating systems based on polyurethane and thin film of perfluorohexadecan and behenic acid and 2.4-heneicosanedionhave been successfully prepared by spincoating and Langmuir-Blodgett method.

Recommendations

The project has successfully fabricated hydrophobic, friction-resistant, anti-corrosion coating systems for steel based on polyurethane and amphiphilic organic thin films. Through the project, the research team collaborated with the Institute of New Materials, the Belarusian Academy of Sciences and improved the level in the preparation of  thin films and super hydrophobic films. We look forward to the support of the Vietnam Academy of Science and Technology to continue this cooperation.
