The wettability of composite coatings based on polyvinyl alcohol (PVA) and silicon dioxide formed on silicon by the spin coating method from PVA colloid solutions of SiO2 nanoparticles was studied. These coatings modified with hydrolysed heptadecafluorotetrahydrodecyltrimethoxysilane are found to exhibit superhydrophobic and oleophobic properties. It was found that PVA increases the wear stability of SiO2–PVA coatings.
