摘要:
Methacryloyloxyethyl trimethyl ammonium chloric modified nano-lignin corrosion inhibitor (DMC-NL) is prepared and firstly applied as a novel biomass-derived corrosion inhibitor for carbon steel in HCl solution. Nanosizing and modification processes can enhance its anticorrosion ability, the corrosion inhibition efficiency increases with additive amount and can reach 95.3 +/- 0.9% for 15 mg/L. DMC-NL is belonging to the mixed-type corrosion inhibitor and its anti-corrosion ability gradually increases with immersion time. The dense film with two-tier structure forms on metal surface by interactions between N and Fe atoms. This work provides the new insight and opportunity of development of biomass-derived eco-friendly corrosion inhibitor.
