| 英文摘要 | Particulate respirators designed to filtrate fine particulate matters usually do not possess antimicrobial functions. the current study aimed to functionalize particulate respirators with silver nanoparticles (nanosilver or agnps), which have excellent antimicrobial activities, utilizing a straightforward and effective method. we first enhanced the nanosilver-coating ability of nonwoven fabrics from a particulate respirator through surface modification by sodium oleate. the surfactant treatment significantly improved the fabrics' water wet preference where the static water contact angles reduced from 122 degrees to 56 degrees. both macroscopic agar-plate tests and microscopic scanning electron microscope (sem) characterization revealed that nanosilver functionalized fabrics could effectively inhibit the growth of two model bacterial strains (i.e., staphylococcus aureus and pseudomonas aeruginosa). the coating of silver nanoparticles would not affect the main function of particulate respirators (i.e., filtration of fine air-borne particles). nanosilver coated particulate respirators with excellent antimicrobial activities can provide real-time protection to people in regions with seyere air pollution against air-borne pathogens. |
