摘要：

Gelatin/Cerium (III) fibers with high tensile strength and good antibacterial activity were prepared by wet spinning method. The fiber structure and properties were investigated. The optical microscope (OPM) results showed that the fiber had a smooth surface and the fiber diameter was in the range of 60-90 mu m. The mechanical properties tests showed that the tensile strength of gelatin/cerium (III) fibers increased greatly compared with the pure gelatin fibers. Furthermore. it was found that the gelatin/Ce (III) fibers have the antibacterial activity for Escherichia coli and Staphylococcus aureus. (C) 2009 Elsevier B.V. All rights reserved.
