N2 - The corrosion of ASTM A36 steel in acidic environments poses a critical industrial issue, prompting the need for sustainable inhibitors. This study develops a biodegradable PLA/HEC nanocomposite enhanced with ZnO nanoparticles as an inhibitor. Its performance was evaluated using quantum analysis and electrochemical tests, including Tafel polarization and EIS. Quantum analysis showed ZnO enhances electron donation and acceptance for corrosion protection, while electrochemical findings showed PLA/HEC nanocomposite with 0.05 wt% ZnO achieved 93.98 % inhibition efficiency. PLA/HEC-ZnO nanocomposite has potential for sustainable corrosion protection in steel infrastructure, with future exploration focusing on long-term performance, economic feasibility, and practical application testing. This eco-friendly approach integrates quantum and electrochemical insights to optimize corrosion protection.
