N2 - In this study, we have developed a highly efficient and low-cost multifunctional robust polymeric surface coating which are super-hydrophobic, antimicrobial as well as mechanically-strengthened super protective nanocoating. To achieve this development, polyurethane (PU) coating formulations were successfully developed with SiO2@TiO2core-shell nanoparticles prepared via peptization synthesis on mild steel substrate. Easy synthesis steps and low processing temperature is major achievement of this synthesis technique. The idea behind the synthesis of SiO2@ TiO2core-shell nanoparticles was to utilize the mechanical strength of silica and the hydrophobicity, antimicrobial property of the TiO2together. In this coating development nanoparticle concentration was varied from 1% (wt) to 6% (wt) in the coating formulation. Used nanoparticles was modified by using methyl trimethoxy-silane (MTMS) for betterment of the surface. Further investigation on this nanocoating has been carried out by analysing the mechanical behaviour, antimicrobial property, and contact angle measurement. Developed SiO2@ TiO2based polymeric nanocoating has shown improved corrosion/erosion resistance, antimicrobial property, and super-hydrophobic nature (~146 degree) with good anti-scratch property up-to 20N load.
