In situ green preparation and antibacterial activity of copper-based metal-organic frameworks/cellulose fibers (HKUST-1/CF) composite

A copper-based metal-organic frameworks/cellulose fibers (HKUST-1/CF) composite was prepared by in situ and green method. Scanning electron microscopy with energy dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy and X-ray diffraction analyses revealed the functionalization of cellulose fibers (CFs) was successfully achieved by in situ deposition of HKUST-1 via a DMF-free green process. The synthetized HKUST-1/CF composite exhibited excellent antibacterial activity against Escherichia coli and Staphylococcus aureus. The composite was more effective against Gram-positive S. aureus than Gram-negative E. coli. The optimization of process variables indicated that the novel composite could be prepared at room temperature for a short time.
