The self-cleaning properties of water-repellent superhydrophobic surfaces hinder bacterial adhesion. However, one of the most critical issues for superhydrophobic surfaces is the durability or stability of the water-repellent property, since the micro- or nanoscale structures on superhydrophobic surfaces are fragile and can be easily destroyed. Once the superhydrophobicity is lost, the surface anti-adhesion and antibacterial properties will decline. In this work, we present a large-scale fabrication of free-standing silicone-based composite monoliths with strong robust superhydrophobic properties under abrasion, stretching, bending, twisting, knife-scratch, high external pressure and low temperature. The water-repellent property prevents bacteria adhesion, and the addition of antimicrobial particles will further kill any surface-attached bacteria. The general fabrication can be extended to other elastic silicone-based antibacterial materials on a large scale, which are potentially advantageous in practical applications.

具有抗菌特性的柔韧性强的超疏水整体料

疏水性超疏水表面的自清洁特性会阻碍细菌粘附。然而，超疏水性表面的最关键问题之一是疏水性的耐久性或稳定性，因为超疏水性表面上的微米或纳米级结构易碎且易于破坏。一旦失去超疏水性，表面的抗粘连性和抗菌性能就会下降。在这项工作中，我们提出了一种大规模生产的独立式有机硅基复合材料整体材料，该复合材料在磨损，拉伸，弯曲，扭曲，刮擦，高外部压力和低温下具有很强的超疏水性能。拒水性能可防止细菌粘附，并且添加抗菌颗粒将进一步杀死任何表面附着的细菌。
