“…Electrical heaters, which are a kind of electrical resistor that converts electrical energy into thermal energy, have attracted increasing attention due to their widespread applications in many civil, industrial, and military fields as wearable devices, defogging and defrosting, and personal thermal management [ 1 , 2 , 3 , 4 , 5 ]. Based on the Joule’s first law (

, where Q , P , V , R, and t are the generated heat, the electric power, the applied voltage, the resistance of the electrode, and the heating time, respectively), the generated heat is inversely proportional to the resistance of an electrode at a fixed applied voltage [ 6 , 7 ].…”

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.
