Abstract
Developing a superhydrophobic a superhydrophobic anti-icing coating with robust mechanical attributes and chemical resilience is essential for effective anti-icing protection. This study employed fluorine-modified epoxy resin as the resin matrix and Fe3O4@PPy as the photothermal filler to fabricate an ice-resistant superhydrophobic coating, renowned for its exceptional mechanical endurance and corrosion resistance. With its unique micro-nano structure, the resulting coating exhibited an impressive contact angle (CA) of 158.7° and a minimal sliding angle (SA) of <1°. Even after enduring 260 cycles of sandpaper abrasion and tape peeling tests, the coating retained a CA of 157.8° and 154.2° respectively, demonstrating remarkable mechanical durability. The Fe3O4@PPy coatings exhibit excellent ice resistance with water droplets frozen time prolonging to 524 s at −20 °C. Moreover, when exposed to a light intensity of 100 mW/cm2, the coating rapidly heated to 82.4 °C, effectively facilitating de-icing and defrosting, while reducing ice adhesion strength by 88.4 %, underscoring its exceptional anti-icing efficacy. These findings underscore the potential of durable and chemically stable anti-·icing coatings to deliver sustained anti-icing benefits and hold promising practical applications.
期刊介绍:
The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as:
• Chemical, physical and technological properties of organic coatings and related materials
• Problems and methods of preparation, manufacture and application of these materials
• Performance, testing and analysis.
