Epoxy/graphene composites for anticorrosive applications

Coatings are the prevailing, practical and preferred way to safeguard metals from corrosion. Graphene based organic polymer coatings are extensively used as corrosion fortification aids in this era.

A new short review highlights the importance of diverse features of such engineered coatings. Graphene has engrossed momentous responsiveness in many industrial fields due to its superior anti-corrosion and barrier properties. The current review honestly debates the recent works and reports on epoxy/graphene coatings for metal protection from extensive corrosion and oxidation.

Integration of potentially relevant multifunctionalities

The various methodologies to acquire stable-homogenous graphene/epoxy dispersion, covalent functionalisation of graphene, doping of graphene with other nanofillers and their effect on corrosion protection of epoxy/graphene coatings along with detailed corrosion protection mechanism are discussed. The review also outlines the integration of potentially relevant multifunctionalities in epoxy/graphene coatings for self-healing, antifouling, self-cleaning and corrosion protection with suitable examples.

The review has been published in Progress in Organic Coatings, Volume 162, January 2022.
