Novel Hybrid Materials With ZNO Nanoparticles for Anti-Icing and Anticorrosion Coatings on Metallic Surfaces

Abstract
In this work, hybrid materials based on zinc oxide nanoparticles embedded in silane matrix containing different silane precursors were prepared. As organo-modified silane derivatives tetraethylortosilicate (TEOS), (3-glycidyloxypropyl) trimethoxysilane (GPTMS ), phenyltriethoxysilane (PhTES), octyltriethoxysilane (OTES), 3-aminopropyltriethoxysilane (APTES) and octadecyltriethoxysilane (ODTES) were used in order to modifiy the hidrophobicity of the final coatings. The morphology and structure of ZnO based materials have been characterized both as dispersions and as films deposited on different surfaces such as glass and metallic plates. The hydrophobic / superhydrophobic properties of modified ZnO films with alkyl functional groups were evaluated by the contact angle method. In addition, the roughness of coatings with modified silicon precursors of ZnO nanoparticles was determined. Preliminary tests were carried out to determine the anticorrosive effect of coatings made with modified ZnO materials, and it was observed that the ZnO-OTES material exhibits the best behavior when deposited on the metallic surface. The anti icing effect of the coatings was evaluated at -15 ° C and it was observed that the copper surface coating (Cu) with ZnO / TEOS / ODTES material, with a contact angle of 143 ° prove the best efficiency.
