Abstract
The project goal was to functionalize silicon oxide-like surfaces to become hydrophobic using 1H, 1H, 2H, 2H perfluorooctyltrimethoxysilane CF3(CF2)7(CH2)2Si(OCH3)3 (PTFMS). The objective was to find the reaction conditions that will make glass and silicon (Si) wafers hydrophobic. The parameters studied were time, solution concentration, and temperature. Contact angle goniometry was used to measure the hydrophobicity of the samples. The threshold reaction time on glass was 150 hours, and the threshold reaction time for Si wafers was 300 hours. A significant difference in hydrophobicity on glass surfaces exists after 300 hours when the concentration is lowered by a factor of 10. Raising the solution temperature to 30℃ and 60℃ did not increase the hydrophobicity of glass.
