More Information
Summary:A porous material comprises a porous material substrate and nanostructure arrays that are in-situ grown on the porous material substrate; wherein a surface modification layer is arranged on the surface of the nanoarrays, and the surface modification layer is configured to increase the adhesion force between the nanoarrays and the microbes. The porous material is applied to disinfection, which comprises the steps: The porous material with the surface-modified nanoarrays is placed in flowing water, the water flow passes through the gaps of the nanoarrays in a shuttling mode, and in the shuttling flowing process, microbes come into contact with the nanoarrays. The microbes are torn up through the hydrodynamic force and the adhesion force between the nanoarrays and the microbes, so that the microbes are physically ruptured to achieve disinfection.
