| Abstract Scope |
In the study, we have developed a highly efficient and low-cost polymeric super-hydrophobic as well as mechanically-strengthened super protective nanocoating, which can be used as a marine antifouling paint. To achieve this development, polyurethane coating formulations were successfully developed with SiO2@ZnO core–shell nanoparticles on mild steel substrate. The idea behind the synthesis of SiO2@ZnO core–shell nanoparticles was to utilize the mechanical strength of silica and the hydrophobicity of the ZnO together. In this coating development nanoparticle concentration was varied from 1% (wt) to 4% (wt) in the coating formulation. Used nanoparticles was modified by using (3-aminopropyl) triethoxysilane for betterment of the surface. Further investigation on this nanocoating has been carried out by analyzing the mechanical behavior and contact angle measurement. Developed SiO2@ZnO based polymeric nanocoating has shown improved corrosion resistance and super-hydrophobic nature (~150±2⁰) with excellent mechanical properties. |
