摘要：
It has been found that hydrolysis of three-functional alkoxysilanes, such as RFOCH2Si(ORF)3, RF = CH2CF3, CH2CF2CF3, CH2CF2CF2CF3, and CH2CF2CF2CF2CF3, under mild conditions upon exposure to air moisture in the presence of λ-aminopropyltriethoxysilane results in the formation of hydrophobic coatings from fluorine-containing polyorganosilsesquioxanes directly on the substrate. Polymers have a layered ladder structure. The hydrophobicity and low values of refractive indices, surface energy, and its polar component, as well as the simplicity of the preparation, determine the possibility of using polyorganosilsesquioxane films as antireflection protective coatings for laser optics.
