Study on the Preparation and Performance of Dynamic Photothermal Control and UV-Indicating Superamphiphobic Coating on Carbon Fiber Plate

Carbon fiber plates (CFP) are widely used due to their high strength and lightweight properties, but they have poor resistance to water and oil, posing safety risks. This work introduces a method for preparing a superamphiphobic coating on CFP using spraying, which can be dynamically controlled by light and heat, and responds to ultraviolet light. The superamphiphobic carbon fiber plate (SKCFP) achieves a water contact angle of 163° and an oil contact angle of 158°, withstanding 95 h of ultraviolet exposure and 120 wear cycles. It also demonstrates excellent resistance to water impact, acid, and alkali, showing strong potential for use in drones, smart wearables, and more. This study presents a novel method for preparing superamphiphobic coatings, thereby opening up new avenues for the application of CFP in various fields. This sample not only exhibits superamphiphobicity but also cost-effectiveness, outperforming existing studies.
