Solvo-affinity property of glass surfaces modified by self-assembled monolayers of organic and/or inorganic chemicals

• Ultrathin organic and inorganic films had been applied on glass surface.
• Anti-fingerprint property can be evaluated by contact angle of oleic acid.
• The relation of anti-fingerprint property and surface roughness was not found.

Three ultrathin films consisting of dendrimer self-assembled monolayer (SAM), silica particle/dendrimer SAM and silica particles have been prepared on glass surface to develop solvo-affinity and surface roughness and to elucidate the anti-fingerprint effect. The solvo-affinity and surface roughness of the coated films on glass surface were characterized by contact angle measurement and atomic force microscope. The results showed that the fabrication of dendrimer SAM on glass revealed the significantly high hydrophobicity. The loading of silica particles also enhanced hydrophobicity. Thus, the roughness of the surface was enhanced, suggesting the meaningful relation of hydrophobicity and roughness. However, the probable relation of anti-fingerprint property with solvo-affinity and surface roughness was not necessarily found, although the highest anti-fingerprint property was observed for a SAM of 3-aminopropyltriethoxysilane on glass which displayed medium hydrophobicity.
