Thermophysical characteristics and enhancement analysis of carbon-additives phase change mono and hybrid materials for thermal management of electronic devices

A novel zero-noise and clean thermal management technology (TMT), based on phase-change energy storage (TES) technology, has turned out the new vision for researchers industrialist involved in electronics industry. Therefore, this paper highlights a direction by developing nano-enhanced phase change materials (NePCMs) combining carbon-additives with material. Four different types of multi-wall carbon nanotube (MWCNT), graphene oxide (GO), reduced (rGO) nanoplatelet (GNP) were dispersed RT-35HC, used as PCM, combinations mono (MWCNT, GO, rGO GNP) hybrid (GO+MWCNT, rGO+MWCNT GNP+MWCNT) nanoparticles. constant mass percentage 1.0 wt.% was selected both nanoparticles to explore best type dispersion scheme productive effective applications. All synthesized NePCMs characterized using various characterization methods study microstructural features, surface chemistry, lattice dimensions, stability, TES characteristics. The key findings reveal chemical uniform carbon-based RT-35HC without modifying molecular structure. highest conductivity enhancements 182.7%, 183.8% 185.3%, optimum value enthalpy fusions 237.42, 235.35 230.82 J/g achieved NePCM G O + M W C N T , r P respectively comparison NePCMs. phenomenon specific heat capacity explained systematically. Conclusively, minimum subcooling, enhancement smaller phase-transition temperature that GNP+MWCNT can be potentially • Synthesized dispersing MWCNT, GNP Characterized physical, chemical, properties.
