Graphitic Carbon Nitride/Zeolitic Imidazolate Framework-8 Nanoparticles with Antibacterial Properties for Textile Coating

Abstract

Textiles that protect against bacterial nosocomial infections are vital owing to the associated high morbidity, mortality, and a series of challenges that remain in the treatment of drug-resistant bacteria. To overcome these hurdles, a universal coating was developed by combining g-C 3 N 4 /ZIF-8 heterojunction nanoparticles and hydrophobic waterborne polyurethane (PU) to form protective textiles with remarkable antibacterial, anti-adhesive, and antifouling performance. The g-C 3 N 4 /ZIF-8 nanoparticles produce reactive oxygen species to render Escherichia coli and Staphylococcus aureus inactive upon visible light illumination, while hydrophobic waterborne PU hinders bacterial adhesion on coated textiles. The synergy of photocatalytic nanoparticles and hydrophobic polymers is what endows textiles with these remarkable antibacterial properties. Moreover, coated textiles also demonstrate antifouling ability, such as the degradation of methylene blue dyes under visible light illumination. As a proof of concept, this coating was applied to common masks, which were then found to exhibit prominent antibacterial properties. The coating design proposed in this study provides a scalable strategy for the preparation of commercial antibacterial textiles.

Sustainable Synthesis of Ionic Liquid-Functionalized Zinc Oxide Nanosheets (IL@ZnO): Evaluation of Antibacterial Potential Activity for Biomedical Applications

“…A perusal of the literature revealed that extensive research has been done regarding the use of ZnO in the textile industry due to its multifunctional properties such as antimicrobial activity, hydrophobicity, UV protection, and photocatalytic self-cleaning. − Thus, based on the results of low toxicity and significant antibacterial potential as exhibited by the functionalized IL@ZnO, it is further anticipated that the functionalized IL@ZnO material may serve as a good coating material for textile substrates. A functional coating on a textile substrate enhances its performance and properties.…”

Metal–organic-framework-based photocatalysts for microorganism inactivation: a review

“…Mu et al (2021) synthesized g-C 3 N 4 /ZIF-8 heterojunction nanoparticles by an in situ method. 37 g-C 3 N 4 / ZIF-8 exhibited highly effective antibacterial efficacies of 91.1% and 95% against E. coli and S. aureus, respectively, after 30 min of light irradiation. This is because the synergistic combination of g-C 3 N 4 with MOFs would significantly improve the photocatalytic performance by augmenting the specific surface area and active reaction sites.…”

“…In addition, pure MOFs often suffer from rapid recombination of photogenerated electron-hole pairs, resulting in suboptimal photocatalytic performance. In order to solve the above problems and obtain better photocatalytic performance, functionalized MOF-based composites can be constructed by modifying pure MOFs, such as the decoration of linkers or metal centers, 35 metal nanoparticle (NP) doping, 36 construction of core-shell materials, 26 and bonding with semiconductors 37 and conductive materials. 38 These are very promising strategies to realize the visible light response of MOFs and enhance the photocatalytic performance of MOFs.…”

Antibacterial Cellulose Fibers Spun from Ionic Liquid and Enriched with Plant Essential Oils

“…Antibacterial agents are vital in the manufacture of antibacterial fibers, which is the base of the antibacterial textiles. The current antibacterial agents are mainly silver, copper, and other metal antibacterial agents, while they have many limitations, such as high cost, low biocompatibility, and poor comfort. − Therefore, the selection of natural antibacterial agents with good biocompatibility and broad-spectrum durable antibacterial properties is the key to achieving a win–win situation between antibacterial and the comfort of antibacterial fibers. , …”
