Abstract This work concentrated on the fabrication of effective slippery liquid-infused porous surfaces (SLIPSs) to robustly resist ice adhesion by using facile method and smart composition. Firstly, poly(methyl methacrylate) (PMMA), polyhedral oligomeric silsesquioxane end-functionalized PMMA (POSS-ef-PMMA) and polydimethylsiloxane-blocked PMMA (PDMS-b-PMMA) were synthesized. Secondly, micro-sized pores arranged in a three-layer honeycomb-like array at a thickness of ca. 10 μm were elicited on each surface of these three cast polymer films by breath-figure (BF) method. After a separate infiltration of polydimethylsiloxane (PDMS), poly (hydrogenmethylsiloxane) (PHMS) and hexadecane (HD) into the porous matrixes, typical SLIPSs were formed. PDMS-b-PMMA matrix with preferential lipophilicity towards PDMS endowed the obtained SLIPS with better icephobicity. However, HD-induced SLIPSs performed the lowest sliding angles at 6° for 3 μL of water droplet, the lowest ice adhesional strength ranging from 40.8–46.3 kPa and the most robust anti-icing properties of resisting more than 30 icing/de-icing cycles without changing the ice adhesional strength. Such effective anti-icing performance was ascribed to the better liquid nature of HD in contact with water and the solid nature of HD under freezing condition, which could decrease the interfacial friction and abrasion of HD against water or ice.

轻松制备光滑的注油聚合物表面以实现强大的疏冰性

摘要 这项工作集中在制造有效的光滑液体注入多孔表面 (SLIPSs) 上，通过使用简便的方法和智能组合物来稳健地抵抗冰粘附。首先，合成了聚（甲基丙烯酸甲酯）（PMMA）、多面体低聚倍半硅氧烷末端官能化的PMMA（POSS-ef-PMMA）和聚二甲基硅氧烷封闭的PMMA（PDMS-b-PMMA）。其次，微米尺寸的孔排列在三层蜂窝状阵列中，厚度约为 。通过呼吸图 (BF) 方法在这三个流延聚合物薄膜的每个表面上引出 10 μm。在聚二甲基硅氧烷（PDMS）、聚（氢甲基硅氧烷）（PHMS）和十六烷（HD）分别渗入多孔基质后，形成了典型的 SLIPS。PDMS-b-PMMA 基质对 PDMS 具有优先亲脂性，使获得的 SLIPS 具有更好的疏冰性。然而，HD 诱导的 SLIPSs 对 3 μL 水滴的滑动角度最低为 6°，冰粘附强度最低，范围为 40.8-46.3 kPa，最强大的防冰性能可抵抗超过 30 次冰/除冰在不改变冰粘附强度的情况下循环。这种有效的防冰性能归因于 HD 与水接触的较好液体性质和 HD 在冻结条件下的固体性质，这可以减少 HD 与水或冰的界面摩擦和磨损。3 kPa 和最强大的防冰性能，可抵抗超过 30 次结冰/除冰循环，而不会改变冰附着强度。这种有效的防冰性能归因于 HD 与水接触的较好液体性质和 HD 在冻结条件下的固体性质，这可以减少 HD 与水或冰的界面摩擦和磨损。3 kPa 和最强大的防冰性能，可抵抗超过 30 次结冰/除冰循环，而不会改变冰附着强度。这种有效的防冰性能归因于 HD 与水接触的较好液体性质和 HD 在冻结条件下的固体性质，这可以减少 HD 与水或冰的界面摩擦和磨损。
