The researchers demonstrated a flexible graphene epoxy thermosetting material with excellent weather resistance and corrosion resistance.
The nanocomposite coating maintains its high impedance during long-term durability testing.
A functional graphene oxide/epoxy nanocomposite coating with versatility and long-term stability has been developed by the method of chemical bonding and dispersion to achieve the purpose of anti-corrosion and weather resistance .

The prepared nanocomposite material prevents the yellowing of epoxy resin, which proves the durability of the nanocomposite material under ultraviolet light.
In addition, nanocomposites exhibit excellent anti-corrosion properties.
Durability
The results of long-term durability test using electrochemical impedance spectroscopy show that the chemical bond dispersed nanocomposite is better than the physically blended dispersed composite material and pure epoxy coating.
The nanocomposite coating maintains its high impedance during long-term durability testing.
This research has been published in Volume 151 of "Progress in Organic Coatings" in February 2021.
