Low-Friction Performance of Stearic Acid Modification of Nano-Textured ZnO Coating
A simple two-step process has been developed to render the zinc substrate super-hydrophobic, resulting in low-friction properties. The ZnO film with uniform and packed nanorod structure was firstly created by oxidizing the zinc in an aqueous solution containing N,N-dimethylformamide. The as-fabricated surface was then coated by a layer of stearic acid. Scanning electron microscopy, FT-IR Microscope and water contact angle measurement have been performed to characterize the morphological feature, chemical composition and super-hydrophobicity of the surface. The resulting surfaces have a water contact angle as high as 150° and provide effective friction-reducing properties for the zinc substrate.
