Bacterial cellulose/chitosan crosslinked composites were prepared by glutaraldehyde crosslinking,and nanoparticles copper (Cu) were deposited on the surface of the crosslinked composite films by RF reactive magnetron sputtering process.The surface morphology of the nanofiber films was observed by scanning electron microscope.The basic chemical structure,thermal stability and crystal structure of the films before and after crosslinking and copper plating were compared by fourier infrared spectroscopy,thermogravimetric analysis and X-ray diffraction.The distribution of chitosan and copper on the surface of the films was characterized by energy dispersive X-ray spectroscopy.The antibacterial ability to S.aureus and E.coli of the films coated with copper was investigated.The results shown that bacterial cellulose and chitosan did combine effectively,and the addition of chitosan changed the basic morphology,chemical structure crystal morphology and thermodynamic property of bacterial cellulose,and the films after copper plating significantly improved the antibacterial properties (The antibacterial effect against S.aureus and E.coli reached 99.999% after contacted with bacteria for 20min).
