A Facile Approach to Fabricating Antibacterial Textile with High Efficiency and Compact Process

Abstract

The urgent need of healthcare promotes the research and development of antibacterial textiles. However, conventional antibacterial textile is based on the solution method to form bacteriostatic granules on the textile matrix, and this form of textile has lurking perils to environment and low durability. Herein, a distinctive self‐limiting surface chemical reaction, atomic layer deposition (ALD), is proposed that deposit zinc oxide (ZnO) on cotton fabrics pretreated with polydopamine (PDA) to prepare nanocomposite textiles in an exceedingly short time by meticulously regulating the parameters. The results show that the cotton @ PDA treated for only 10 min has more than 95% antibacterial rate against both S. aureus and E. coli, which is better than that treated by ALD or PDA alone. Besides, the significance of reactive oxygen species in the antibacterial activity of PDA and ZnO composite coating is confirmed by introducing vitamin E for the first time. Thanks to PDA pre coating and the unique interface combination mode of ALD, the antibacterial textiles introduced in this study have excellent durability. The strategy proposed in this paper can provide a theoretical basis for the antibacterial modification of medical devices.

Recent Advances in Superhydrophobic and Antibacterial Cellulose-Based Fibers and Fabrics: Bio-inspiration, Strategies, and Applications

“…Figure 15 c shows that cells attached to the surface from the fetal bovine serum (FBS) solution transitioned from a hydrophilic surface to a hydrophobic surface and eventually covered the entire surface, and the trapped air cannot impede the transitional growth of cells after 4 days of culture [ 213 ]. In pursuit of long-term and effective antibacterial effect, it is favorable to combine super-hydrophobic surfaces with antimicrobial agents [ 6 , 176 , 212 , 218 ].…”

“…Photodynamic therapy (PDT) contact killing works based on light-induced reactive oxygen species, which has also been widely used for the treatment of antibacterial fabrics [88,122,173,227]. Graphene nanomaterials, ZnO, TiO 2 , Ag NPs, MOF, and anthraquinone compounds are the commonly used antibacterial materials in PDT [88,167,[170][171][172][173]176]. Song et al [88] reported a synergistic antibacterial strategy based on super-hydrophobic bacteriostatic and photodynamic sterilization, and found that surface super-hydrophobicity can significantly improve the bactericidal activity of PDT by reducing the number of surfaceadhering bacteria.…”

ZnO‐Reinforced Thermal Regulating Microcapsules with Double‐Layer Shell via Atomic Layer Deposition

“…Clothing is vulnerable to bacteria in the process of utilization, so endowing microcapsules antibacterial activities will be an undoubtedly immense boost to their application value. Nano ZnO has previously been proved to possess excellent antibacterial activities, [57][58][59] so it could be reasonably speculated that the ALD induced DLSPCM with ZnO outer shell has antibacterial properties. The growth states of E. coli and S. aureus after being treated with different microcapsule samples are shown in Figure 6a-h.…”

Engineering Sizable and Broad-Spectrum Antibacterial Fabrics through Hydrogen Bonding Interaction and Electrostatic Interaction

“…The construction of antibacterial fabrics through chemical bonds is an effective method to enhance their durability and longevity. Elaborate structure design of antibacterial agents is necessary to form special covalent bonding or cross-linking between the agents and fabrics. ,, Additionally, magnetron sputtering was also employed to deposit antimicrobial agents onto the surface of fabrics, and antimicrobial materials can also be grafted onto fabrics using γ-radiation to fabricate antibacterial fabrics. , The limited durability of antibacterial fabrics produced through physical methods coupled with the complex production processes involved in chemical bonding poses significant constraints to the large-scale production of antibacterial fabrics. An ideal strategy for large-scale production of antibacterial fabrics should be simple and rapid, while the fabrics should prioritize long-lasting durability.…”
