The Fabrication of Mechanobactericidal Coating and Its Application in Mechanical Sterilization

Abstract

Bacteria are difficult to be eliminated because of their multi‐drug resistance, which brings significant threats to public health. Among the antibacterial methods, mechanobactericidal surfaces provide a possible approach to solving this problem. In this study, a generally used mechanical sterilization is developed by fabricating a nanostructured coating. The functional coating is simply fabricated by growing zeolitic imidazolate frameworks (ZIFs, ZIF‐8 mixed with ZIF‐67) nanospikes on the surface of the fabric substrate in situ. The fabricated ZIF nanospikes are stable and effective, with the sterilization efficiency approaching 99.9999%. This technique provides a fast, safe, and low‐cost antibacterial method without drug resistance, which can be potentially used in hospitals, emergency treatments, and superbug protection in the future.
