A novel fluorinated silica nanoparticles were synthesized using 1H,1H,2H,2H-perfluorodecyltriethoxysilane (FAS17) and further characterized to evaluate the wettability alteration capability. Previous research (1, 2) has utilized fluoroalkanoic acids as the coating agent. First, the in-situ functionalization method employs tetraethoxysilane (TEOS) as the silica precursor and water-soluble amine as the catalyst. It is then further functionalized with 1H, 1H, 2H, 2H-perfluorodecyltriethoxysilane (FAS17) with ethanol to attain the novel fluorinated silica nanoparticles. The preliminary characterization from FTIR analysis indicated that the in-situ functionalization was successfully applied. The new bonding formation with fluorine attachment on the novel fluorinated silica nanoparticles is capable to alter the wettability of the solid surface, exhibiting self-cleaning properties.
