Novel epoxy curing strategy based on GO and glass fiber

A polymer matrix composite with a physical barrier network can efficiently inhibit corrosion on carbon steel.

In a new paper, 3-(2-Aminoethylamino) propyldimethoxymethylsilane modified graphene oxide (A-GO) and glass fiber (GF) were incorporated into Epoxy (EP) matrix, and EP/GF/A-GO composite coating with dual physical barrier network was prepared. The electrochemical impedance spectroscopy (EIS) showed that the impedance modulus of EP/GF/A-GO composite coating was highest among the different coatings, indicting EP/GF/A-GO composite coating with dual physical barrier network could significantly enhance the corrosion protection properties.

Excellent anti-corrosion protection performance

Even after 45 days of immersion, the value of impedance modulus of the EP/GF/A-GO composite coating was above 3.9 × 107 Ω cm2. Moreover, the anti-corrosion protection mechanism of EP/GF/A-GO composite coating was investigated. EP/GF/A-GO composite coating has an excellent anti-corrosion protection performance.

The study has been published in Progress in Organic Coatings, Volume 167, June 2022.

EC Tech Report Sustainability

Making coating systems more environmentally compatible is a burning issue for everyone in the industry, and one that is being fuelled by the European Green Deal. Learn all you need to know about sustainable coatings, how to produce coatings in a more environmentally friendly way and how to give coated products a longer service life. You will find an overview in the EC Tech Report of the many various approaches being adopted. We will dive deep into the European Green Deal, its key points and main purpose as well as consequences for the coating industry, see which new raw materials are being developed to replace or lower the content of products in the SVHC group and learn about different approaches to sustainable paint formulation.
