Boosting Copper Biocidal Activity by Silver Decoration and Few‐Layer Graphene in Coatings on Textile Fibers
Abstract The outbreak of the Coronavirus disease 2019 (COVID‐19) pandemic has highlighted the importance of developing antiviral surface coatings that are capable of repelling pathogens and neutralizing them through self‐sanitizing properties. In this study, a novel coating design based on few‐layer...

| description | Abstract The outbreak of the Coronavirus disease 2019 (COVID‐19) pandemic has highlighted the importance of developing antiviral surface coatings that are capable of repelling pathogens and neutralizing them through self‐sanitizing properties. In this study, a novel coating design based on few‐layer graphene (FLG) is proposed and silver‐decorated micro copper flakes (CuMF) that exhibit both antibacterial and antiviral properties. The role of sacrificial anode surfaces and intrinsic graphene defects in enhancing the release of metal ions from CuMF embedded in water‐based binders is investigated. In silico analysis is conducted to better understand the molecular interactions of pathogen‐repelling species with bacterial or bacteriophage proteins. The results show that the optimal amount of CuMF/FLG in the coating leads to a significant reduction in bacterial growth, with reductions of 3.17 and 9.81 log for Staphylococcus aureus and Escherichia coli, respectively. The same coating also showed high antiviral efficacy, reducing bacteriophage phi6 by 5.53 log. The antiviral efficiency of the coating is find to be doubled compared to either micro copper flakes or few‐layer graphene alone. This novel coating design is versatile and can be applied to various substrates, such as personal protective clothing and face masks, to provide biocidal activity against both bacterial and viral pathogens. |
