摘要：

The most important and generally accepted way to characterize highly hydrophobic surfaces is by their wettability. This property involves a contact angle (CA) measurement between a surface and a liquid droplet. There were obtained nanostructured silica thin films from organo-modified silane precursors; a systematic study on the modification of film-forming hybrids surfaces obtained by co-hydrolysis and polycondensation of tetramethoxysilane with different alkyltrialkoxysilanes was performed. The analysis of the surface energy by contact angle method allows the determination of surface energy components and their correlation with wetting properties. The properties of the final hybrids obtained by the sol-gel process were significantly affected by the precursor alkyl chain lengths.
