摘要：In this study, a durable, reusable, effective and large-area molding method was proposed to fabricate hierarchical structures on the CF/PEEK composite surface. The hierarchical structures were fabricated using a combination of sandblasting and anodizing treatments on the metal surface. Subsequently, a hot-pressing process was adopted for producing structures that matched the metal templates. The rough surface was modified by (Heptadecafluoro-1,1,2,2-tetradecyl)trimethoxysilane with low surface energy to obtain superhydrophobicity. Scanning electron microscopy was utilized to observe the surface morphologies and structure. The chemical composition and roughness were analyzed by FT-IR spectroscopy and the laser microscopy, respectively. Wettability was characterized through contact angle measuring instruments, and static and dynamic sliding contact angles were obtained to be 158.23 degrees and 8.38 degrees, respectively. After the abrasion test, the CF/PEEK composite surface still maintained reasonable mechanical stability. Comparing with the untreated sample, CF/PEEK superhydrophobic surface exhibited excellent anti-icing performance with freezing time increasing from 54 to 514 s at - 20 degrees and icing adhesion strength reducing to 30.5 kPa. Although the fabrication of composite surface with water repellency presented here is useful for anti-icing, it can also be applied in other applications that require superhydrophobic surfaces.
