4. Description Abstract

This study employed core-shell polymerization to synthesize three types of interpenetrating polymer networks (IPNs): (epoxy / resole) IPN/ppy@nanoSiO2, (Epoxy /resole) IPN/ppy@nanoZnO, and (epoxy - resole) IPN/ppy@nanoFe3O4. The prepared compounds were subjected to comprehensive characterization using Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), X-Ray Diffraction (XRD), Thermogravimetric Analysis (TGA), and Differential Scanning Calorimetry (DSC) techniques. These IPNs were subsequently applied as self-healing coatings on carbon steel (C1010) alloy. The inhibition efficiencies of the coated carbon steel were then evaluated in a 1M HCl solution using Electrochemical Impedance Spectroscopy (EIS). The results demonstrated an increase in the Rp values according to the following order: (epoxy /resole) IPN/ppy@nanoSiO2 > (epoxy / resole) IPN/ppy@nanoZnO > (epoxy/ resole) IPN/ppy@nanoFe3O4. Notably, the (epoxy /resole) IPN/ppy@nanoSiO2 coating exhibited a remarkable inhibition efficiency of 100%.
