Weather resistant multifunctional nanocomposite
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.
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.
