Enhancement of Hydrophobic and Anti-Corrosive Performance of Epoxy Coatings Based on Graphene Oxide and Nano-Silica/Graphene Oxide Hybrid
In this study, we developed a fluorine-free hydrophobic and anti-corrosion coatings using epoxy resin (EP) containg SiO2 nanoparticles, mercaptobenzimidazole (MBT) and graphene oxide (GO) nanoparticles which was synthesized via sol–gel method. Hybrid network was characterized by Fourier transform infrared (FTIR), scanning electron microscope (SEM), energy-dispersive spectroscopy (EDS), pull off and salt spray. Structural properties of obtained coatings demonstrated uniform distribution and dispersion with nano-sized inorganic particles and contact angle tests demonstrated that increasing the GO, which is associated with a decrease in surface energy, increased the coatings' oleophobicity. Pull off test showed that the adhesion strength in case of textured and non-textured surfaces were 4.2 MPa and 2.46 MPa, respectively. Results indicated that adhesion strength of the coating increased due to surface texturing of obtained coating. Salt spray results suggest a significant improvement in the barrier performance of EP coatings through the addition of SiO2/GO nanohybrids. By increasing the GO and GO/SiO2 content of the fluorine chains, the resistance to corrosion, Taber abrasion, and hydrophobicity all increased dramatically.
期刊介绍：
The journal Silicon is intended to serve all those involved in studying the role of silicon as an enabling element in materials science. There are no restrictions on disciplinary boundaries provided the focus is on silicon-based materials or adds significantly to the understanding of such materials. Accordingly, such contributions are welcome in the areas of inorganic and organic chemistry, physics, biology, engineering, nanoscience, environmental science, electronics and optoelectronics, and modeling and theory. Relevant silicon-based materials include, but are not limited to, semiconductors, polymers, composites, ceramics, glasses, coatings, resins, composites, small molecules, and thin films.
