摘要: A one-pot procedure for the synthesis of polyethylene tethered on multi-walled carbon nanotubes by in situ ethylene copolymerization with an olefin-type comonomer, -alkene functionalized multi-walled carbon nanotubes (MW―CH＝CH2) is reported. The covalent linkage between polyethylene and multi-walled carbon nanotubes is demonstrated. The MWCNTs are chemically oxidized first by a strong oxidizing agent and then functionalized with chlorocarbonyl groups (MW―COCl) via reacting with thionyl chloride. The MW―CH＝CH2 are obtained by esterification of -undecylenyl alcohol with MW―COCl. The MW―CH＝CH2 may serve as olefin-type comonomers to further synthesize core-shEll structured copolymers with a multi-walled carbon nanotubes core grafted with side chains of polyethylene via rac-(en)(THInd)2ZrCl2 copolymerization catalyst. The core-shell structured nanocomposites were characterized by means of 1H-NMR, SEM, FTIR and TGA. The results confirmed the formation of polyethylene chains growing from the surface of multi-walled carbon nanotubes.
