“…In Table 3, it can also be found that the electrical percolation threshold of CNT/polymer composites with semicrystalline thermoplastic matrices (PP, PE, PEO, PA) is always higher than those of CNT/epoxy composites. Hu et al [88] first used coagulation method to prepare MWNT/PET composites and found that the percolation threshold of the composite was 0.9 wt%. Seo et al [89,90] presented that the conductivity of CNT/PP composites was increased with increasing the CNT content and the electrical percolation threshold was formed between 1 and 2 wt% CNTs.…”

Abstract. The state-of-art and key problems of carbon nanotube (CNT) based polymer composites (CNT/polymer composites) including CNT/polymer structural composites and CNT/polymer functional composites are reviewed. Based on the results reported up to now, CNTs can be an effective reinforcement for polymer matrices, and the tensile strength and elastic modulus of CNT/polymer composites can reach as high as 3600 MPa and 80 GPa, respectively. CNT/polymer composites are also promising functional composite materials with improved electrical and thermal conductivity, etc. Due to their multi-functional properties, CNT/polymer composites are expected to be used as low weight structural materials, optical devices, thermal interface materials, electric components, electromagnetic absorption materials, etc. However, the full potential of CNT/polymer composites still remains to be realized. A few key problems, such as how to prepare structurecontrollable CNTs with high purity and consistently dependable high performance, how to break up entangled or bundled CNTs and then uniformly disperse and align them within a polymer matrix, how to improve the load transfer from matrix to CNT reinforcement, etc, still exist and need to be solved in order to realize the wide applications of these advanced composites.

Hu (Hu et al, 2006) reported a low electrical percolation threshold (0.9 wt%) in PET/MWCNT nanocomposites fabricated via coagulation, and the electrical conductivity reached 10-2 S/m at higher filler loading (~5 wt%). A small percolation threshold was reported by Steinert and coworkers in PET/SWCNT nanocomposite films prepared using a solution mixing and casting method.…”

“…When electric field is applied in samples containing CNTs, the electrons are permitted to go through the sample due to the creation of the interconnecting conductive channels. [26][27][28][29] The pPLACNTs nanocomposite films showed higher electrical conductivity than samples not containing ESO (PLACNTs). In the sample PLACNT-5, the conductivity of the film was 10 −6 S/cm whereas the conductivity of the film in pPLACNT-5 was 10 −4 S/cm.…”

Poly(lactic acid)/epoxidized soybean oil/carbon nanotubes (PLA/ESO/CNTs) nanocomposites were prepared by the solution blending process, and the influence of ESO on the properties of the composites was studied. Differential scanning calorimetry and X-ray diffraction revealed that the addition of CNTs improved the crystallinity of the nanocomposites. The modulus increased with the addition of CNTs content in the composites. Morphological characterizations were done by scanning electron microscopy and transmission electron microscopy. Electrical conductivity of PLA/ESO/CNT composites increased with the addition of CNTs. This study revealed that the addition of ESO facilitated the dispersion of the CNTs in the PLA matrix. C
