Abstract

Background: Currently, 75% of global epoxy polymers are based on bisphenol A (BPA), a substance identified as reprotoxic, posing challenges to the development of eco-friendly epoxy coatings.

Methods: Our study reports the synthesis of three novel bio-based anti-corrosion coatings composed of vanillin alcohol diglycidyl ether (DGEVA) and silica nanoparticles, which were added to improve the adhesion to AA2024 substrates.

Findings: The coatings present high adhesion (∼7 MPa) and excellent thermal stability (>295 °C), besides good corrosion protection of the hybrid coating (impedance modulus of ∼4 MΩ cm⁻² in 3.5 wt% NaCl for > 68 days). The results reveal that proper silica distribution fosters adhesion and extends lifespan via metal oxide-polymer bonds.
