Most existing materials may not satisfy all the fundamental requirements of modern civilization. This chapter summarizes the latest advances in the study of hybrid graphene nanocomposites and their application as thermal interface materials and some functional energy materials, in particular, for thermal management of energy and electronic devices. The main properties of hybrid graphene nanocomposites are described. The main attention is paid to the thermal properties of such materials, in particular, thermal conductivity and the possibilities of its growth due to various changes in the morphology and other properties of nanocomposites. The technology of obtaining a new nanocomposite based on mesoscopic microspheres, polymers, and graphene flakes is considered.

Radiation from the sun continually generates enormous solar energy reaching the atmosphere and then radiates back into the outer space over a while. The energy source is considered to be potential renewable thermal energies if effectively harnessed and stored. Thermal energy storage could be in either cold or heat form for later use for either cooling and heating purposes respectively; it can also be utilized for electricity production. The development of highly efficient and cost-effective heat storage materials has been an emerging school of thought for researches into smart methods of heat storage. The authors briefly review the state-of-art carbon-based composite phase change materials (PCM) that have been employed in applications that are related to thermal storage. Various types of recently developed carbon composites with improved thermal storage properties have been succinctly discussed. The technological implications of employing the identified materials in the thermal storage applications were also highlighted and discussed.

“…Compared with carbon nanotubes and graphene, conductive carbon black (CB) is an inexpensive and relatively efficient electrically conductive filler, has the characteristics of small particle size (nanoscale), large specific surface area and rough surface, and is widely used in electrically conductive polymer composites. [29][30][31] Theoretically, there will be strong interactions and adsorptions between CB nanoparticles and organic PCM molecular chains because of the small particle size (nanoscale), large specific surface area and rough surface of CB. The organic PCM/CB composites with high electrical conductivity can be obtained via the simple vacuum impregnation, and the obtained SSPCCs may be applied in electric-to-thermal energy conversion and storage according to the Joule's Law.…”

In this work, a unique electrically conductive polyethylene glycol (PEG)/carbon black (CB) shape-stable phase change composite (SSPCC) for peak load regulating of electric power system was prepared via a vacuum impregnation approach. Scanning electron microscope (SEM), differential scanning calorimeter (DSC) and X-ray diffraction (XRD) were used to study the micro morphology, crystallization behavior, crystallization structure and thermal properties. Leakage test and DSC results showed that when the PEG content in PEG/CB SSPCC was as high as 86 wt%, the phase change enthalpy and relative enthalpy efficiency were up to 147.7 J/g and 95.1%, respectively. Fourier transform infrared (FTIR) and XRD showed no chemical reaction between CB and PEG. Thermal cycling test showed that the PEG/CB SSPCC had excellent thermal stability and thermal reliability. Moreover, the good electro-tothermal conversion ability of PEG/CB SSPCC (0.2 S/m) provided rich possibilities for peak load regulating of electric power system and corresponding thermal energy storage.
