Bio-based anti-corrosion coating material for mild steel
The present work intended to develop linseed oil-based anti-corrosion nanocomposite coating material. In this context, an epoxy resin was prepared by the epoxidation of linseed oil (ELO). Curing agents (H1 and H2) were also prepared by the malenisation of linseed oil, and condensation of malenised linseed oil with diethylenetriamine. A simple eco-friendly method was employed for the reduction of graphene oxide using 10% sodium hydroxide solution.
Protection efficiency of 99.98%
The composite coating material was prepared by direct incorporation of the reduced graphene oxide (rGO) into the linseed oil without using any organic solvent. Electrochemical data indicated that the corrosion rate of mild steel is reduced to around 5000 times for the rGO-ELO-H2 system with protection efficiency of 99.98% and the exhibited stability up to 10 days in 3.5 wt% NaCl solution.
The study has been published in Progress in Organic Coatings, Volume 159, October 2021.
This book brings together all the disciplines involved in the creation and use of corrosion protection coatings for metals. It presents the latest insights into the quality and chemistry of surfaces, the proper way to prepare them by conversion treatment, the function of resins and anticorrosion pigments in paints, and novel concepts in corrosion protection. As an added bonus, all the standards and directives mentioned in the text are grouped together in their own chapter for a better overview.
