In this study, in order to surface modification of zinc oxide, titanium dioxide and boehmite nanoparticles the new organic compound was introduced. Creating new functional groups with oleic acid did not represent the satisfactory results, so in this work, the oleic acid was turned to the much more active compound, and then on the surface of the mentioned nanoparticles was assembled. The novel reagent named N-(3-triethoxysilylpropyl) oleamide (N-TESPO) was synthesized through chemical modification of oleic acid which easily capable of functionalizing a variety of oxide nanoparticles to superhydrophobic nanoparticles. This reagent was synthesizedin a two-stage reaction of oleic acid. To investigate the properties of the superhydrophobic nanoparticles with the chemical surface modification method, the contact angle test, SEM and FTIR were applied. The results of the water contact angle tests illustrated that the water contact angle of the surface covered with the modified zinc oxide, titanium dioxide, and boehmite nanoparticles was 158°, 163°, and 161°, respectively that proved the superhydrophobicity characteristic of this modified nanoparticles.
