We propose a new superhydrophobic surface that contains a carbon nanotube (CNT)-implanted poly(dimethylsiloxane) (PDMS)/adhesive multilayer. The adhesive provides very strong adhesion between the CNT-implanted PDMS layer and the substrate, and the CNTs on the surface exhibit superhydrophobicity. Therefore, the CNT-implanted PDMS/adhesive (CIPA) layer provides a highly reliable surface for superhydrophobicity. The fabricated CIPA surface performs far better than previously reported surfaces in terms of stability tests, such as contamination and solvent tests, and physical contact, including thermal pressure, bending, adhesion, and water jet tests. If a portion of the CIPA surface is destroyed, the surface is immediately restored because the material can regenerate the surface to its initial state. The surface can therefore maintain its superhydrophobicity even when damaged in rough environments, without self-healing or additional repair. Furthermore, because the adhesive is sprayed and coated on the surface of the substrate, a CIPA surface can be formed on three-dimensional shapes, including curved surfaces, and on various substrates.
我们提出了一种新型超疏水表面，其包含植入碳纳米管（CNT）的聚二甲基硅氧烷（PDMS）/粘合剂多层结构。该粘合剂在植入碳纳米管的PDMS层与基底之间提供了非常强的粘附力，并且表面的碳纳米管表现出超疏水性。因此，植入碳纳米管的PDMS/粘合剂（CIPA）层为超疏水性提供了高度可靠的表面。在诸如污染和溶剂测试等稳定性测试以及包括热压、弯曲、粘附和水射流测试在内的物理接触方面，所制备的CIPA表面的性能远优于先前报道的表面。如果CIPA表面的一部分被破坏，由于该材料能够将表面再生至其初始状态，表面会立即恢复。因此，即使在恶劣环境中受损，该表面也能保持其超疏水性，无需自愈或额外修复。此外，由于粘合剂是喷涂在基底表面上的，所以可以在包括曲面在内的三维形状以及各种基底上形成CIPA表面。
