激光诱导向后转移制备Ag@Cu微纳结构涂层及抗菌性能验证
Laser-induced backward transfer for fabrication of Ag@Cu micro-nano structured coatings and antibacterial properties verification
摘要
Abstract
A commercially available transparent phone case was used as the substrate,and an Ag@Cu mi-cro-/nano-composite antibacterial coating was fabricated on its surface via laser-induced backward transfer(LIBT).The results indicated a positive correlation between laser power and the elemental content of the microstructured coating,with the mass ratios of Ag and Cu increasing as laser power increased.This ap-proach enables efficient fabrication under ambient atmospheric conditions with a simple and cost-effective process.The resulting microstructured coating exhibited pronounced antibacterial activity against both Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli.At laser powers of≥16 W,the antibacterial rate exceeded 99.99%,and the increased copper mass ratio further enhanced antibacterial efficacy.These findings address key limitations of conventional technologies by enabling high-precision construction of micro-/nano-structures on transparent substrates.Moreover,the processing parameters are precisely controllable,supporting scalable manufacturing and offering a general strategy for functional-izing the surfaces of other transparent organic materials.Overall,a practical route for producing antibacte-rial phone cases is established,providing methodological guidance for the design and fabrication of ad-vanced antibacterial surfaces and addressing bacterial contamination and insufficient antibacterial perfor-mance in mobile phone casings.关键词
