Abstract
Reparation of superhydrophobic coating with anti-icing and deicing function is crucial for outdoor power equipment. In this study, silica was combined with polyurea to prepare polyurea-silica composite particulates, which were then incorporated into siloxane along with graphite powder to create a robust superhydrophobic photothermal coating. The developed coating, characterized by its micro-nano hierarchical structure and the blackbody characteristic of carbon materials, exhibits outstanding superhydrophobic properties and photothermal conversion efficiency. The photothermal performance leads to a rapid temperature increase to 90.3 °C within 600 s under 100 mW/cm2 of irradiation. The coating demonstrates remarkable anti-icing properties, delaying the freezing time of a 100 µL droplet for up to 2956s, coupled with a low ice adhesion strength measuring 20∼30 kPa. Moreover, the coating displays excellent photothermal de-icing properties, facilitating the rapid melting of frozen droplets and their easy removal from the surface. Anti-icing/de-icing experiments on power system insulators confirmed that the coating exhibits outstanding anti-icing and photothermal deicing performance, making it a viable alternative for practical applications.
期刊介绍:
The aim of the journal is to provide a respectful outlet for ''sound science'' papers in all research areas on surfaces and interfaces. We define sound science papers as papers that describe new and well-executed research, but that do not necessarily provide brand new insights or are merely a description of research results.
Surfaces and Interfaces publishes research papers in all fields of surface science which may not always find the right home on first submission to our Elsevier sister journals (Applied Surface, Surface and Coatings Technology, Thin Solid Films)
