Abstract : This study successfully develops a versatile method of producing superhydrophobic surfaces with micro/nano-silica hierarchical structures
on glass surfaces. Optically transparent super hydrophobic silica thin films were prepared by spin-coating silica particles suspended
in a precursor solution of silane, ethanol, and H2O with molar ratio of 1:4:4. The resulting super hydrophobic films were characterized by
scanning electron microscopy (SEM), optical transmission, and contact angle measurements. The glass substrates in this study were
modified with different particles: micro-silica particles, nano-silica particles, and hierarchical structures. This study includes SEM micrographs
of the modified glass surfaces with hierarchical structures at different magnifications.
