“…Buckypapers have been extensively used in a variety of applications as filters [ 9 ], fire retardancy materials [ 10 ], electromagnetic shielding materials [ 11 , 12 ], catalyst supports [ 13 , 14 ], actuators [ 15 , 16 ], sensors [ 17 , 18 ], supercapacitors [ 19 , 20 ], and fuel cell electrodes [ 21 , 22 ]. They have even been used in medical applications [ 23 ], but probably the most widespread usage of them is the incorporation into polymeric matrices for the enhancement of their mechanical, electrical, or thermal properties [ 7 , 8 , 24 , 25 , 26 ].…”

High volume fraction carbon nanotube (CNT) composites (7.5–16% vol.) were fabricated by the impregnation of CNT buckypapers into epoxy resin. To enhance the interfacial reaction with the epoxy resin, the CNTs were modified by two different treatments, namely, an epoxidation treatment and a chemical oxidation. The chemical treatment was found to result in CNT length severance and to affect the porosity of the buckypapers, having an important impact on the physico-mechanical properties of the nanocomposites. Overall, the mechanical, electrical, and thermal properties of the impregnated buckypapers were found to be superior of the neat epoxy resin, offering an attractive combination of mechanical, electrical, and thermal properties for multifunctional composites.

“…This result may be attributed to the fact that a greater CNT content improves the contact area among CNTs, which in turn building an effective Double penetration structure and a thick conductive network. There is a greater variety of paths for currents that subsequently strengthens the conductivity 44–46 . The conductivity of the experimental group with more than 3 wt% of CNTs does not fluctuate significantly, suggesting that any higher CNT content does not affect the conductivity of composite films.…”

In this study, CNT/PP/PC conductive composite films were prepared by compounding PP (polypropylene)/PC (polycarbonate) (1:1) and carbon nanotubes (CNT) using a physical blending and hot pressing method. Next, Fourier transform infrared spectroscopy, thermogravimetric analysis, differential scanning calorimetry, and water contact angle measurement are conducted in order to characterize the properties of CNT/PP/PC conductive films. The results showed there is no chemical reaction inside the PP/PC composite film with the addition of CNT. Neither the CNT composite film containing 3 wt% nor the control film decomposed thermally within 220°C. The water contact angle increased from 88.5° for the control film to 110.99° for the composite film containing 3 wt% CNT. This indicates that the film has good thermal stability and hydrophobic properties. The percolation threshold was obtained when the content of CNT was 3 wt%, and the best conductivity of the CNT/PP/PC composite film was 5.53 S/m at this time. In order to improve the tensile properties of the film, a small amount of polyurethane (TPU) was added to the film, and the maximum tensile strength was 24.91 Mpa when the content of TPU was 6.7%. This study can provide a strategy for the practical application of flexible electronic devices.

“…Nonetheless, the porosity and mean pore radius demonstrated decreasing trends when ZnO/CNTs photocatalyst loadings were further increased from M3 to M5. This can be attributed to the decrease in the distance between individual ZnO/CNTs and enhancement in packing density 57,58 . Moreover, the denser packing structure of ZnO/CNTs photocatalyst would also increase the tortuosity of the porous structure, hence reduces waterways and imposes greater resistance for water inflow to the PSF interphase layer, causing delaying the diffusion between water and NMP 59–61 .…”
