英文摘要: Radiation crosslinked ultrahigh molecular weight polyethylene (X-UHMWPE) powder was prepared by gamma-ray irradiation under nitrogen atmosphere with a dose of 50-200 kGy at a dose rate of 7 kGy/h and further annealing in vacuum at 120 degrees C for 4 h. The crosslinked powder was characterized by FT-IR spectroscopy, gel content, and hot-press molding. Then, X-UHMWPE was added to pristine UHMWPE to prepare a composite with 0-25 wt % filler. The morphology, wear resistance, and tensile property of the composite were investigated. Using X-UHMWPE as a filler could sufficiently improve the wear resistance of the composite. Adding 25 wt % X-UHMWPE (dose: 150 kGy) improved wear resistance by 130% and retained approximately 90% tensile strength and 70% ductility. Wear-resistant and ductile UHMWPE composite may be potentially used for artificial joint replacement and engineering devices. The proposed route is useful in fabricating UHMWPE material with excellent comprehensive performance or functional polymer composite. (C) 2016 Wiley Periodicals, Inc.
