Investigation of anti-corrosion ability of PANI/Sn- MOFS composites prepared by sonication

This study investigates the effects of incorporating PANi-Sn MOFs, synthesized via the ultrasound method, into epoxy resin at concentrations of ۰.۱%, ۰.۲%, and ۰.۳%. The results demonstrate significant improvements in corrosion resistance, mechanical strength, and adhesion properties. Corrosion resistance, measured by Rp, increases notably with higher PANI-Sn MOFs content, peaking at ۰.۳%. Polarization resistance also improves, indicating better electrochemical stability. Adhesion strength, tested through pull-off measurements, shows a marked increase, with the ۰.۳% mixture exhibiting the strongest bonding. Impact resistance is similarly enhanced, suggesting improved toughness and durability. The ultrasound-assisted synthesis of PANi-Sn MOFs contributes to their uniform dispersion within the epoxy matrix, leading to enhanced overall performance. These findings highlight the effectiveness of PANi-Sn MOFs in reinforcing epoxy resin, making it more suitable for applications requiring high corrosion resistance, strong adhesion, and impact tolerance. The optimal performance at ۰.۳% concentration underscores the potential of this composite for advanced industrial applications.
