中文摘要 本研究受具有滑溜表皮的動物啟發，通過結合動態界面釋放誘導的皺褶與自組裝的含矽雙嵌段共聚物（diBCP），成功構建了具有液態濕潤皺褶表面的耐用滑溜抗生物污染塗層。核心的 diBCP 材料是聚苯乙烯-嵌段-聚二甲基矽氧烷（PS-b-PDMS）。由於含矽聚合物具有低表面能的內在特性，它們在經過控制的熱處理後，能輕鬆地在表面上流動並覆蓋，形成一層滑溜的濕潤層，從而消除與生物分子的極性相互作用。此外，微皺褶的圖案產生了彎曲的表面，提供了更少的附著點，使生物體難以附著。不同於傳統的滑溜液體填充多孔表面，所提出的類液態 PDMS 濕潤層與 PS 化學鍵合，穩定且滑溜，但不會流失。研究了具有不同 PDMS 體積分數的 PS-b-PDMS 雙嵌段共聚物，以比較 PDMS 段長對抗生物污染性能的影響。研究了 diBCP 表面的特性，包括加工容易性、透明度以及抗生物污染、防冰與自清潔能力，並在各種條件下進行測試。在工業應用中，能夠製造不需要使用含氟化合物和昂貴材料前體的環保型矽基潤滑層，具有一定的優勢。
英文摘要 Inspired by animals with a slippery epidermis, durable slippery antibiofouling coatings with liquid-like wetting buckled surfaces are successfully constructed in this study by combining dynamic-interfacial-release-induced buckling with self-assembled silicon-containing diblock copolymer (diBCP). The core diBCP material is polystyrene-block-poly(dimethylsiloxane) (PS-b-PDMS). Because silicon-containing polymers with intrinsic characters of low surface energy, they easily flow over and cover a surface after it has undergone controlled thermal treatment, generating a slippery wetting layer on which can eliminate polar interactions with biomolecules. Additionally, microbuckled patterns result in curved surfaces, which offer fewer points at which organisms can attach to the surface. Different from traditional slippery liquid-infused porous surfaces, the proposed liquid-like PDMS wetting layer, chemically bonded with PS, is stable and slippery but does not flow away. PS-b-PDMS diBCPs with various PDMS volume fractions are studied to compare the influence of PDMS segment length on antibiofouling performance. The surface characteristics of the diBCPs─ease of processing, transparency, and antibiofouling, anti-icing, and self-cleaning abilities─are examined under various conditions. Being able to fabricate ecofriendly silicon-based lubricant layers without needing to use fluorinated compounds and costly material precursors is an advantage in industrial practice.
