基于ZIF-67原位合成的织物制备及光热抗菌研究
Preparation of fabrics via in situ growth of ZIF-67 nanoparticles and their photothermal antibacterial properties
摘要
Abstract
To effectively eliminate drug-resistant bacteria on textiles,ZIF-67 nanoparticles were synthesized in situ on the surfaces of common polyester and cotton fabrics,resulting in modified polyester(ZIF-67@Dacron)and modified cotton(ZIF-67@Cotton).The obtained fabrics were characterized by X-ray diffraction(XRD),Fourier-transform infrared spectroscopy(FTIR),and field emission scanning electron microscopy(FE-SEM).Their photothermal performance and antibacterial efficacy were also evaluated.Results confirmed the successful growth of ZIF-67 nanoparticles on both fabric types.Under near-infrared(NIR)light irradiation for 30 seconds,the surface temperatures of ZIF-67@Dacron and ZIF-67@Cotton increased to 95 ℃and 120 ℃,respectively.This photothermal property remained stable over five heating-cooling cycles.Owing to their excellent and stable photothermal performance,both modified fabrics achieved a bactericidal efficiency of over 99.9%against drug-resistant Gram-positive and Gram-negative bacteria after just 3 minutes of NIR irradiation.In this study,we successfully fabricated two types of functional fabrics based on in situ-synthesized ZIF-67 nanoparticles,demonstrated their highly effective antibacterial properties,and presented a promising strategy for developing antibacterial textiles.关键词
