AI Technical Summary
Existing superhydrophobic coatings suffer from insufficient durability and poor chemical stability under extreme environments such as low temperature, high humidity, and corrosion, and their preparation processes are complex, which limits their application in extreme environment engineering fields.
A simple sol-gel method was used to prepare a superhydrophobic SiO2/rGO composite coating. By combining SiO2 with reduced graphene oxide (rGO), surface modification was performed using a silane coupling agent, and perfluorooctyltriethoxysilane was added to impart superhydrophobic properties. The coating was then deposited on the substrate surface using a spraying process.
It achieves excellent photothermal performance, superhydrophobicity and chemical stability in harsh environments, can significantly delay icing and accelerate ice melting, and has good impact resistance and long-term stability, making it suitable for transportation, aerospace and power transmission and other fields.
