| 中文摘要 | polyethylene (pe) chains grafted onto the sidewalls of swcnts (swcnt-g-pe) were successfully synthesized via ethylene copolymerization with functionalized single-walled carbon nanotubes (f-swcnts) catalyzed by rac-(en)(thind)(2)zrcl2/ mao. here f-swcnts, in which alpha-alkene groups were chemically linked on the sidewalls of swcnts, were synthesized by prato reaction. the composition and microstructure of swcnt-g-pe were characterized by means of h-1 nmr, fourier transform infrared spectroscopy (ftir), raman spectroscopy, thermogravimetric analyses (tga), field-emission scanning electron microscope (fesem), and transmission electron microscope (tem). nanosized cable-like structure was formed in the swcnt-g-pe, in which the pe formed a tubular shell and several swcnts bundles existed as core. the formation of the above morphology in the swcnt-g-pe resulted from successfully grafting of pe chains onto the surface of swcnts via copolymerization. the grown pe chains grafted onto the sidewall of the f-swcnts promoted the exfoliation of the mass nanotubes. comparing with pure pe, the physical mixture of pe/f-swcnts and in situ pe/swcnts mixture, thermal stability, and mechanical properties of swcnt-g-pe were higher because of the chemical bonding between the f-swcnts and pe chains. |
