“…Furthermore, the coating of Ag@GO and its reduced derivative have rendered the free motion of the nanocomposite, indicating the cutting and shearing of the cell membranes through the motion of the sharp edges as well as the encapsulation of the bacteria is not a reasonable explanation for the antibacterial activity of coated and hydrophobized samples. 24,25 According to previous studies, the antiviral activity of the resulting Ag@GO/PP can be explained by the antiviral mechanism of the AgNPs. In particular, the outer coat of the viruses can strongly interact with the AgNPs on the surface of the materials, which efficaciously prevents the viruses from attachment to the cell receptors.…”

Herein, poly(propylene) (PP) was hydrophilized with oxidating agents and solvents, followed by dip‐coating with silver nanoparticles anchored GO sheets (Ag@GO) prepared by the in‐situ method as reported in our previous study to obtain silver@graphene oxide‐coated poly(propylene) (Ag@GO/PP). The impact of the modifying agents, dipping times, and coating concentrations on the antibacterial activities were studied accordingly via the inhibition zone method. The fabrics were re‐hydrophobized with the reduction of Ag@GO and the functionalization with stearic acid (SA) to form silver@reduced graphene oxide‐coated poly(propylene) (Ag@rGO/PP) and silver@graphene oxide/SA‐coated poly(propylene) (Ag@rGO‐SA/PP), respectively. Characterization of pretreated and modified PP samples was carried out by various modern analysis methods. Simultaneously, the cytotoxicity of the active layers, the release of Ag+ ions, and durability after washing were also investigated. The obtained results representing PP fabrics pretreated with HNO3/isopropanol and dipped in Ag@GO concentration of 2 g/L four times prove a sufficient approach for improving hydrophilization and bio‐compatibility for the PP samples. The fabrics greatly show an impressive interaction with precursors, mostly high antibacterial activity even after four washing cycles via appropriate releasing of Ag+ to ensure the safety in usage. They further suggest that the prepared fabrics could be utilized for actual application as a face mask.

“…The results implied that cotton fabric surfaces had good antibacterial activity against S. aureus and E. coli . As well, Wu et al [ 71 ] fabricated antibacterial superhydrophobic coatings contained Ag NPs and silver stearate on the cotton fabric. The coatings showed good water and acid resistance.…”

Microorganisms have existed for hundreds of millions of years and they have adapted to colonize on surfaces. [1] Bacteria are ubiquitous in the human living environment. Most bacteria spread through medical equipments and contacting with each other. [2] All over the world, the diseases caused by bacterial infections have brought terrible catastrophe to human beings. [3][4][5][6][7] Generally, people infected with infectious diseases are directly or indirectly related to contact with pathogenic microorganisms. The main stages of the attachment of bacteria at the interface include the migration of bacteria to the surface, the reversible and irreversible interactions between bacteria and the interface, the specific adsorption of bacteria on the substrate, and the proliferation of bacteria, thus forming a bacterial biofilm on the surface (Figure 1). [8] The bacteria can multiply quickly under suitable conditions, which induce various diseases and cause invalidation of apparatus. The colonization of bacteria on surfaces can result in chronic infections, [9] the failure of medical implants, [10] the biological corrosion of industrial equipments, [11] reducing various surface properties, such as petroleum and other pipelines systems, clothes, and other harmful phenomena. [12] Currently, antibiotics are mainly used to inhibit or kill bacteria to maintain surface hygiene and prevent infections. However, as bacteria develop resistance to antibiotics, it is suggested that antibiotics should be much more cautiously used. It is estimated that antimicrobial resistance infections will kill as many as 10 million people every year by 2050. [13] Antimicrobial resistance is now an urgent international issue that requires imperative solutions, more effective antibacterial techniques are needed to fight bacterial infections. Inspired by the superwetting properties of plants and marine life, Li et al. [14] reviewed the research progresses of the preparation of superwetting materials including of superhydrophobic/superoleophilic and superhydrophilic/underwater superoleophobic materials and their applications for removal of organic pollutants, which provided a basis for the design of a new type of superwetting materials that efficiently remove organic pollutants in the water. Similarly, Tian et al. [15] developed a superwetting thin-film nanofibrous composite membrane with antifouling, self-cleaning, and oil-in-water emulsions separation properties. The as-prepared carbon nanotubes (CNTs) layer with superhydrophilic and underwater superoleophobic properties could absorb water as a selective layer to remove oil droplets from oil-in-water emulsions to present antifouling. The self-cleaning properties were promised by the continuously up-flowed permeate water. They claimed that the work provided a new insight for developing oil/water separation membranes which suffer from fouling and clogging. Also, Li et al. [16] summarized the recent progresses in smart polymeric materials for fabricating switchable superwettability surfaces and their oi...

“…(2) Multifunctional. In addition to the functions of self-cleaning, 9,10 corrosion resistance, 11,12 and oil-water separation 13,14 based on the wettability of the superhydrophobic surfaces, the additional functions inherited from the coating materials, such as anti-bacterial, 15 UV shielding, 16 and selfhealing 17 properties, are attracting more and more attention. (3) Eco-friendly.…”

Various strategies have been developed to fabricate superhydrophobic surfaces with the guidance of adding rough micro-nano structure and decreasing surface energy. However, it is still a challenge to prepare a superhydrophobic coating with multifunction, eco-friendliness, and broad applicability to substrates. The mussel-inspired polydopamine (PDA) possessing superior material-independent adhesion was considered as the promising candidate material. Herein, a hierarchical superhydrophobic PDA coating was fabricated on Cu substrate via a facile self-assembly method. Thanks to PDA's selfroughening and self-adhesive effects, the coating obtains sufficient surface roughness and good interface adhesion. The superhydrophobic coating
