［Objective/Significance］ Icing and ice accumulation on solid surfaces are widelyobserved on various exposed facilities，posing significant hazards to industrial production and humandaily life. The development of efficient，stable，and environmentally friendly anti-icing/de-icingcoatings is of great engineering significance in solving the icing problem in extreme climates.［Analysis/Discussion/Progress］We systematically review the recent research progress in multi-scaledesign strategies combining photothermal functionalization and interfacial functionalization for anti-icing/de-icing surfaces，and elucidate the mechanism of solid surface ice-phobicity and anti-icing/de-icing coatings from the mechanistic level. Categorized based on energy conversion mechanisms，the characteristics and applications of various photothermal materials are introduced. Additionally，the advantages and challenges of design strategies combining phase change energy storage，photothermal functional materials，and interfacial functionalization are summarized.［Conclusion/Prospect］ To address the demands for anti-icing/de-icing in complex environments，the combination of photo-thermal and interfacial functionalization has significant potential for long-lasting anti-icing/de-icingperformance. This strategy thereby offers a novel direction for the development of all-weather anti-icing/de-icing coatings.
