Abstract

Polymeric-based nanocomposite coatings were synthesized by reinforcing epoxy matrix with titanium nanotubes (TNTs) loaded with dodecylamine (DOC). The performance of the developed nanocomposite coatings was investigated in corrosive environments to evaluate their anti-corrosion properties. The SEM/TEM, TGA, and FTIR analysis confirm the loading of the DOC into the TNTs. The UV-Vis spectroscopic analysis confirms the self-release of the inhibitor (DOC) in response to the pH change. The electrochemical impedance spectroscopic (EIS) analysis indicates that the synthesized nanocomposite coatings demonstrate superior anticorrosion properties at pH 2 as compared to pH 5. The improved anticorrosion properties of nanocomposite coatings at pH 2 can be attributed to the more effective release of the DOC from the nanocontainers. The superior performance makes polymeric nanocomposite coatings suitable for many industrial applications.

Highlights

Carbon steel pipelines are used widely in the oil and gas industry for the transportation of liquids and gases
Pallets, and ethanol were purchased from Sigma Aldrich, Germany
The titanium dioxide nanotubes (TNTs) are relatively uniform in size and ordered in the stack

Summary

Introduction

Carbon steel pipelines are used widely in the oil and gas industry for the transportation of liquids and gases. Carbon steel pipelines suffer from poor corrosion resistance in solutions containing aggressive species like chloride ions [1,2,3]. Owing to the deleterious effect of corrosion, different techniques have been employed to improve the corrosion resistance of carbon steel [5,6,7]. Towards this goal, the corrosion resistance of steel has been improved by incorporation of insoluble, hard ceramic particles such as carbides and nitrides into steel [8]. Organic inhibitors containing nitrogen and acetylenic alcohols have demonstrated promising efficiency [11,12,13]
