Weather resistant multifunctional nanocomposite

Researchers exhibit a flexible epoxy graphene thermoset with excellent weather and corrosion resistance.

The nanocomposite coating retained its high impedance over long-term durability tests.

The chemical-bonding-dispersed method was used to develop a functional graphene oxide/epoxy nanocomposite coating with multifunctional properties and long-term stability for anticorrosion and weather resistance purposes.

The as-prepared nanocomposite prevented the yellowing of epoxy resin, demonstrating the nanocomposite’s durability under UV light. Furthermore, the nanocomposite exhibited excellent anticorrosion properties.

Durability properties

The results of the long-term durability tests performed using the electrochemical impedance spectrum indicated that the chemical-bonding-dispersed nanocomposite was superior to the physically blended dispersed composite and pure epoxy coating. The nanocomposite coating retained its high impedance over long-term durability tests. This study demonstrated the durability of the anticorrosion, mechanical, thermal, and degradation properties of the designed coating material before and after UV irradiation.

The study has been published in Progress in Organic Coatings, Volume 151, February 2021.

Anticorrosive Coatings

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.
