“…In fact, alongside with enhanced mechanical properties, this morphology allows a high electrical conductivity with the lowest percolation threshold, as compared with the other morphological organization [ 19 , 20 , 21 ]. Therefore, the past decade has witnessed an almost explosive growth of CPCs with a segregated carbon-based fillers network [ 10 , 13 , 22 , 23 , 24 ]. Yu et al [ 25 ] first demonstrated that the electrical conductivity of CNT/poly(vinyl acetate) increased dramatically after incorporating CNTs in the segregated network.…”

Conductive polymer composites with carbonaceous fillers are very attractive and play a significant role in the field of electric heaters owing to their lightweight, corrosion resistance, and easy processing as well as low manufacturing cost. In this study, lightweight reduced oxide graphene/carbon nanotube/natural rubber (rGO/CNT/NR) composites were fabricated by a facile and cost-effective approach, which consists of rGO assembling on rubber latex particles and hydrogels formation due to the interaction network established between carbonaceous fillers and subsequent mild-drying of the resulting hydrogels. Thanks to the amphiphilic nature of GO sheets, which can serve as a surfactant, the hydrophobic CNTs were easily dispersed into water under ultrasound. On the basis of both the high stable rGO and CNTs suspension and the assembling of rGO on rubber latex, a three-dimensional segregated network of CNT and rGO were easily constructed in macro-porous composites. Either the segregated network and macro-porous structure endowed the resulting composites with low density (0.45 g cm−3), high electrical conductivity (0.60 S m−1), and excellent electric heating behavior, when the weight content of rGO and CNTs are 0.5% and 2.5%, respectively. For electric heating behavior, the steady-state temperature of the above composites reaches 69.1 °C at an input voltage of 15 V.

“…A similar technique was proposed by Chan et al, Zhang et al, and Jia et al using ultrahigh‐molecular‐weight polyethylene (UHMWPE), and by Grunlan et al using latex rubber. Recently, Wu et al employed this technique for a blend containing polypropylene (PP), and Zheng et al used it for a thermoplastic elastomer obtained by the dynamic vulcanization method. These reports demonstrated that the distribution of nanofillers in a polymer blend with phase separation is often different from the equilibrium one owing to the high viscosity of such blends.…”

A new technique to show good electroconductivity was proposed using carbon nanotube (CNT) localization in cocontinuous immiscible polymer blends comprising ultrahigh-molecular-weight polyethylene (UHMWPE) and polycarbonate (PC). When UHMWPE was added to PC/CNT in the molten state in an internal mixer, CNTs started moving to the UHMWPE phase. However, CNTs require a long time to diffuse into the UHMWPE phase owing to a low diffusion constant. Consequently, they remain at the interface between PC and UHMWPE. When the blends have cocontinuous structure, the localized CNTs at the phase boundary act as a conductive path, leading to a good electroconductivity. Although a similar morphology is obtained by adjusting the balance of interfacial tensions among polymers and CNT, it is difficult to find a system showing appropriate interfacial tensions. As the present method is applicable to various polymer blends, it will be an important technique to prepare a conductive nanocomposite.
