The self-assembled monolayers (SAMs) of perfluorocarboxylic acids were fabricated on several metal oxide powders. Perfluorododecanoic acid and perfluorooctadecanoic acid were used to study the effect of chain length on SAM. Alumina, Tantalia, Titania, and Zirconia were the metal powders used. The formation of the SAMs was confirmed by DRIFT(Diffuse Reflectance Infrared Fourier Transform) spectroscopy. Since the perfluorohydrocarbons are well known for their hydrophobicity, the resulting monolayers are also expected to have high hydrophobicity. The quality of DRIFT spectra of SAMs was dependent on the powder size as well as the element of metal oxides.
