Designing a novel epoxy composite system with dual self-healing/barrier anti-corrosion functions using SiO2 nano-platforms decorated by Polyaniline (PANI) nanoparticles doped with zinc metal ions is the major objective of this research attempt. In order to verify the PANI synthesis on SiO2 nanoparticles several analyses such as UV-visible, FTIR, XRD and FE-SEM were performed. The epoxy nanocomposite coatings containing SiO2-PANI-Zn2+ ,SiO2- Zn2+ and SiO2 nanoplatforms were fabricated and applied on carbon steel. The nanocomposite coatings anti-corrosion capability was examined by salt spray methods. The results of FE-SEM images demonstrated the zinc doped PANI nanoparticles formation on the SiO2. The great potency of SiO2 -PANI-Zn2+on the epoxy coating anti-corrosion performancepromotion, self-healing-barrier properties enhancement and cathodic delaminatio resistance improvement were obtained on carbon steel.
