【摘要】 采用绿色原位沉积的方法制备铜系金属有机框架材料/纤维素纤维(HKUST-1/CF)复合材料。通过扫描电镜观察及能谱、傅里叶变换红外光谱及XRD的分析,证明HKUST-1已通过不使用DMF的绿色方式原位沉积在纤维素纤维上。合成的HKUST-1/CF复合材料表现出对大肠杆菌和葡萄球菌的良好抗菌性。工艺条件的优化表明可以在室温下快速制备新型的HKUST-1/CF复合材料。更多还原

【Abstract】 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(SEM/EDX),Fourier transform infrared(FTIR) spectroscopy and X-ray diffraction(XRD) analyses revealed the functionalization of cellulose fibers 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 E.coli and S.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.更多还原
