Abstract
A novel organic nano-silicon material (NPs-SM) was synthesized by Mannich reaction using acetophenone, formaldehyde and amino silicon nanoparticles (Si NPs), which was prepared by KH550 and ascorbic acid through a simple one-step procedure. NPs-SM was characterized by FT-IR, XPS, SEM-EDS and TEM and studied of its slow-release performance. The inhibition efficiency was investigated with electrochemical impedance spectroscopy, potentiodynamic measurements, and mass loss analysis, respectively. Additionally, SEM, XPS, AFM and CA analyses were carried out to study the relationship between structural details and surficial performance of the protective layer formed on the steel. Intriguingly, the corrosion inhibition efficiency of NPs-SM significantly increases with increasing temperature in strong acid environments, reaching 94.94 %. This precisely matches the characteristics required for high-temperature and high acid corrosion inhibitors, this study is expected to provide new ideas for corrosion research under special conditions.
期刊介绍:
Applied Surface Science covers topics contributing to a better understanding of surfaces, interfaces, nanostructures and their applications. The journal is concerned with scientific research on the atomic and molecular level of material properties determined with specific surface analytical techniques and/or computational methods, as well as the processing of such structures.
