采用溶液共混法制备了乙二醇接枝多壁碳纳米管（EG-g-MWCNTs）抗静电聚对苯二甲酸乙二醇酯（PET）材料。首先将MWCNT羧化，然后用EG酯化以产生EG-g-MWCNT。通过红外光谱、透射电镜、拉曼光谱、热重分析和电导率测试表明，EG改性后，MWCNTs的团聚程度降低，电导率保持在4.278 S/cm。另一方面，EG-g-MWCNTs在PET合成单体之一的EG中分散良好，从而保证了其与PET的良好相容性。结果表明，PET/EG-g-MWCNTs纳米复合材料（0.1wt%）的电导率比纯PET提高了7个数量级，达到了抗静电水平。
Antistatic Poly(ethylene terephthalate) (PET) materials had been successfully prepared through solution-blending incorporation of ethylene glycol-graft-Multi-walled carbon nanotubes (EG-g-MWCNTs). MWCNTs were first carboxylated and then esterified with EG to yield EG-g-MWCNTs. The FT-IR spectra, TEM images, Raman spectra, TGA curves and electrical conductivity were investigated, which indicated that the agglomeration degree of MWCNTs has been reduced and the conductivity keeps as high as 4.278 S/cm after the modification of EG. On the other hand, EG-g-MWCNTs dispersed well in EG, which was one of the synthetic monomers for PET, and thus ensured its good compatibility with PET. As a result, the electrical conductivity of PET/EG-g-MWCNTs nanocomposites (0.1 wt%) was seven orders of magnitude higher than pure PET and reached the antistatic level.
