Insights into the corrosion inhibition of novel 1,8-naphthalimide derivatives bearing primary amino groups on Q235 steel in chloride-contaminated concrete pore solution

Key Points

• Corrosion inhibition shows significant effectiveness of novel 1,8-naphthalimide derivatives on Q235 steel.
• More than 80% inhibition efficiency was observed in chloride-contaminated concrete pore solution.
• Assessment was done using electrochemical techniques to evaluate corrosion rates and inhibition performance.
• These findings highlight the promise of using amino-substituted 1,8-naphthalimide derivatives to enhance steel protection.
