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.

This article focuses on exploring how the electrical conductivity and densification properties of metallic samples made from aluminum (Al) powders reinforced with 0.5 wt % concentration of multi-walled carbon nanotubes (MWCNTs) and consolidated through spark plasma sintering (SPS) process are affected by the carbon nanotubes dispersion and the Al particles morphology. Experimental characterization tests performed by scanning electron microscopy (SEM) and by energy dispersive spectroscopy (EDS) show that the MWCNTs were uniformly ball-milled and dispersed in the Al surface particles, and undesirable phases were not observed in X-ray diffraction measurements. Furthermore, high densification parts and an improvement of about 40% in the electrical conductivity values were confirmed via experimental tests performed on the produced sintered samples. These results elucidate that modifying the powder morphology using the ball-milling technique to bond carbon nanotubes into the Al surface particles aids the ability to obtain highly dense parts with increasing electrical conductivity properties.

<p>The chemical functionalization of amino multi-walled carbon nanotubes (MWCNT-NH<sub>2</sub>) by selenium dioxide (SeO<sub>2</sub>) was used to produce Poly [MWCNT/Imidoselenium] composite. The prepared poly-composite was characterized by FTIR, SEM, TEM, XRD, UV, DSC and TGA. The DC electrical conductivity of poly-composite was 4.3×10<sup>-4</sup> S/cm due to the interaction between the nanotubes. </p>
