中文摘要	multi-walled carbon nanotubes (mwcnts)/polyethylene (pe) nanocomposites were prepared via in situ polymerization with mwcnts supported bis- (cyclopentadienyl) zirconium dichloride (cp2zrcl2) catalyst. x-ray photoelectron spectroscopy (xps) and field emission scanning electron microscope (fesem) results imp e that cp2zrcl2 catalyst was immobilized in the surface of the mwcnts supports via a bridge of methylaluminoxane (mao). the efficient dispersion of mwcnts in pe matrix and the strong compressive forces associated with pe on the mwcnts were demonstrated by means of transmission electron microscope (tem), fesem and raman spectra. with introducing 0.2 wt% mwcnts, both the tensile strength and elongation of mwcnts/pe nanocomposite were improved by factors of 1.6 (from 29 to 45 mpa) and 1.5 (from 909% to 1360%) comparing with the pure pe, respectively. morphology observation of fractured surface revealed that the pe firmly adhered to the nanotubes, which was responsible for the significant improvement of the mechanical properties of nanocomposites. thermal stabilities of the nanocomposites were significantly improved. in addition, the mwcnts/pe nanocomposites showed very high ultraviolet (uv) shielding property, which could increase photooxidative stability of the pe. polym. compos., 31:507-515, 2010.
