Corrosion Resistive Conducting Polymeric Nanocomposite-based Coatings On Steel: a Mechanistic Insight

Strategic Insights

— 1 min read

Research on conducting polymers and polymer-based nanocomposites has gained significant attention in recent decades, particularly for their potential as corrosion-resistant coatings on steel. Conducting polymers have been found to offer anodic corrosion resistance and barrier protection to steel surfaces, making them a promising area of research. The study, conducted by researchers at the Indian Institute of Science, explored the mechanisms of corrosion resistance provided by conducting polymer coatings, specifically those based on polyaniline (PANI) and polypyrrole (PPy) and their nanocomposites.

Key Takeaways:

  • Conducting polymers have been researched extensively for their potential as corrosion-resistant coatings on steel, with significant breakthroughs in the last four decades.
  • Polyaniline (PANI) and polypyrrole (PPy) and their nanocomposites have been identified as promising conducting polymers for corrosion resistance.
  • PANI provides corrosion resistance through anodic and barrier protection mechanisms, while PPy offers both anodic and barrier protection.
  • The intelligent release of doped corrosion inhibitive anions from the conducting polymer coating is a significant aspect of its corrosion protection mechanism.
  • The limitations of conducting polymer coating are briefly discussed in the study.
  • The research provides a mechanistic insight into the corrosion resistive conducting polymeric nanocomposite-based coatings on steel.

Statistics:

  • Over four decades have passed since research on conducting polymers as corrosion-resistant coatings on steel began.
  • PANI provides anodic corrosion resistance to steel surfaces due to its higher oxidising ability.
  • PPy offers both anodic and barrier protection to steel surfaces.
  • The intelligent release of doped corrosion inhibitive anions from the conducting polymer coating is a crucial aspect of its corrosion protection mechanism.
  • 2025 marks the publication year of the study.
