摘 要：Herein, we report a new and simple method for the preparation of metallic copper nanospheres decorated cellulose nano?ber composite（CuN Ss/CNFs）. Initially, the cellulose acetate nano?bers(CANFs were electrospun followed by deacetylation and anionization to produce functional anionic cellulos nano?bers（f-CNFs）. The Cu Cl2 precursor was deposited on the f-CNFs（Cu Cl2/CNFs） by a simple dippin method. Then the CuCl2/CNFs were reduced under vacuum by using aluminum foil to produce the CuN Ss CNFs. The resultant Cu NSs/CNFs composite was characterized by various microscopic and spectroscopi methods. Fourier transform infrared spectroscopy（FT-IR） con?rmed the successful functionalization o anionic groups with the CNFs. The ?eld emission scanning electron microscopy（FE-SEM） and transmis sion electron microscope（TEM） results con?rmed the formation of Cu NSs on the surface of CNFs. From the scanning electron microscopy-energy dispersive spectroscopy（SEM-EDS） analysis, the weight per centage of Cu was found to be 23.5 wt%. The successful reduction of Cu O to metallic Cu was con?rme by X-ray photoemission spectroscopy（XPS） and X-ray diffraction（XRD） analyses. Mechanism has bee proposed for the formation of metallic Cu sphere on CNFs.
