摘要

ASTM A36钢在酸性环境中的腐蚀是一个关键的工业问题，促使需要可持续的抑制剂。本研究开发了一种以ZnO纳米颗粒为抑制剂的可生物降解PLA/HEC纳米复合材料。通过量子分析和电化学测试，包括塔菲尔极化和EIS，对其性能进行了评价。量子分析表明，ZnO增强了PLA/HEC纳米复合材料的电子给予和电子接受，电化学结果表明，0.05 wt% ZnO的PLA/HEC纳米复合材料的缓蚀效率为93.98%。PLA/HEC-ZnO纳米复合材料在钢铁基础设施中具有可持续防腐的潜力，未来的探索重点是长期性能、经济可行性和实际应用测试。这种环保的方法集成了量子和电化学的见解，以优化腐蚀保护。

Biodegradable PLA/HEC-ZNO Nanocomposite for corrosion protection of ASTM A36 steel: A combined quantum and electrochemical analysis

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.
