A robust photothermal superhydrophobic anti/de-icing composite coating fabricated from BP/SiO2 on a modified fluorocarbon coating base
Anti/de-icing coatings to equipment surface are emergingly becoming an essential protection against ice formation and accumulation, especially when they serve in harsh environments. Herein, a novel approach for obtaining photothermal superhydrophobic anti/de-icing FCF-BP/SiO2 coating with prominent abrasion resistance properties was presented. The fluoroalkyl silane and amino silane were polymerized at elevated temperatures and then closely combined with the resin and curing agent to obtain a film-forming polymer. This polymerization process involved the reaction of amino group on the surface of the modified fluorocarbon resin with the isocyanate group in the curing agent. Then the polypyrrole-coated basalt scales (BP) and SiO2 NPs were employed to the modified coating system to construct a wear-resistant microscopic surface structure by the inverse infusion process (IIP). The water contact angle (CA) and the sliding angle (SA) of the tested coating was up to 155° ± 2° and 1.5° ± 0.5°, respectively, delaying the icing time to 656 s and maintaining the ice adhesion strength lower than 20 kPa after several icing-deicing cycles. It was verified that the FCF-BP/SiO2 coating remained superhydrophobic and exhibited excellent mechanical durability even after 300 times of abrasion with sandpaper and 100 times of tape-peeling. Even at −10 °C, the frost (accumulated at −10 °C for 2 h) or ice cube (0.5 g) on the FCF-BP/SiO2 coating could be effectively removed by 1.00 Sun within approximately 309 s and 760 s, respectively. This provides potential applications for fabricating functional anti/de-icing materials in some prospective fields including marine or aviation fields.
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.
