This study presents a novel electro-photothermal superhydrophobic (EPS) nanocomposite coating designed for all-day durable anti-icing and de-icing applications. The EPS coating integrates superhydrophobicity, electrothermal, and photothermal effects, offering both physical and chemical self-cleaning attributes. Key findings include: 1. **Superhydrophobicity and Self-Cleaning**: The EPS coating exhibits a water contact angle of over 160°, demonstrating superior superhydrophobic properties. It also demonstrates effective self-cleaning capabilities, removing contaminants and maintaining its functionality. 2. **Anti-Icing Performance**: The coating delays icing by about four times compared to a conventional coating. At −20 °C, the EPS coating reduces de-icing time by about 5 times compared to purely photothermal performance and about 4 times compared to purely electrothermal performance. 3. **De-Icing Performance**: The EPS coating efficiently melts ice, with ice removal times ranging from 2.4 minutes to 12.6 minutes, depending on the conditions (sunny, cloudy, or cold nights). The coating's ability to maintain temperatures above 0 °C through photothermal effects on sunny days and to utilize both electrothermal and photothermal effects on cloudy and cold nights, respectively, further enhances its de-icing capabilities. 4. **Durability and Stability**: The EPS coating demonstrates excellent durability, withstanding mechanical wear, water impact, UV aging, and chemical resistance tests. It maintains its superhydrophobic and photothermal properties over multiple cycles of heating and cooling. 5. **Outdoor Applications**: The EPS coating effectively melts snow and ice in various weather conditions, including sunny days, cloudy days, and cold nights. Snow melting times range from 127 seconds to 202 seconds, demonstrating the coating's practical effectiveness in real-world scenarios. Overall, the EPS coating represents a significant advancement in anti-icing and de-icing technologies, offering a versatile and durable solution for a wide range of applications.This study presents a novel electro-photothermal superhydrophobic (EPS) nanocomposite coating designed for all-day durable anti-icing and de-icing applications.
