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
