Abstract
Hybrid coatings were prepared by sol-gel method from sols on the base of TMSPM ((3-(trimethoxysily)propyl methacrylate) TEOS (tetraethylorthosilicate) on glass, corundum, polished steel and subsequently heat treated at 90 degrees C/3 h or at 150 degrees C/3 h. The morphology and microstructure of hybrid coatings were described by SEM and AFM Properties like refractive index and thickness were measured with spectrophotometry. The abrasion resistance of hybrid coatings highly depends on the temperature of heat treatment. The tests of chemical resistance and measurement of porosity using nitrogen adsorption confirmed that the hybrid coating prepared from 100 % TMSPM is lightly porous. Therefore the hybrid material is not suitable as a protective barrier coating on the metal materials.
