Abstract

［Objective/Significance］Anti-waxing coating，as a key technology for inhibiting wax deposition，have garnered significant attention in both mechanistic research and engineering applications.［Analysis/Discussion/Progress］ This paper briefly introduced classical and emerging wax deposition mechanisms，reviewed advancements in anti-waxing coating technologies，and systematically analyzed their technical characteristics. Low-surface-energy coating inhibited wax adhesion by reducing interfacial energy， but their mechanical durability was insufficient. Superhydrophilic coating formed a physical barrier through a dynamic water film，but their performancewas susceptible to fluctuations in crude oil water content. Bionic superamphiphobic coating integratedmicro-nano hierarchical structures with low surface energy properties，combining both anti-deposition capabilities and multifunctional advantages. However，current technologies still faced bottlenecks such as weak long-term protective stability，poor adaptability to complex operating conditions，and high preparation costs.［Conclusion/Prospect］Future research should focus on developing smart coating materials with self-healing properties，optimizing surface microstructure design and environmental response mechanisms，while exploring low-cost manufacturing processes. Technological breakthroughs in these areas will promote the engineering application of anti-wax coating in oil and gas transportation，providing innovative solutions for pipeline flow assurance.

Key words： wax deposition mechanisms; oil pipelines; anti-waxing; bionic superamphiphobic coating
