Incorporation of Especially Doped PANI into Epoxy Resin for Fabricationof Self-Healing Coatings

Herein, we synthesized polyaniline—an efficient and smart anticorrosive material—andincorporated it into an epoxy matrix. Our study aimed to evaluate and compare the role of differentdoping agents in enhancing the corrosion resistance of the employed anticorrosive pigments.Specifically, we used phytic acid, tannic acid, and hydrochloric acid as disparate doping agents.Thorough characterization of the prepared nanofibers was conducted using FTIR analysis. Notably,the results revealed that phytic acid-doped coatings exhibited superior anti-corrosion performance.This improvement can be attributed to stronger complexation and hindered penetration paths forcorrosive agents. These findings contribute significantly to the development of more efficient andsustainable corrosion protection materials.
