Abstract

Efficient, clean and quiet thermal management has become a vital challenge in for cooling of electronic devices. To enhance the capability and efficiency of passive thermal management , novel composite materials have been designed by the combination of graphene nanoplatelets (GNPs), multiwall carbon nanotubes (MWCNTs), aluminium oxide (Al 2 O 3) and copper oxide (CuO) dispersed in the RT-28HC used as a phase change material (PCM). The series of mono and hybrid nano-enhanced phase change materials (NePCMs) were synthesized using constant mass fraction of 1.0 wt.% of each type of nanoparticles to establish the optimum NePCM in terms of thermal properties for efficient thermal management of microelectronics. Various material characteristic techniques such as ESEM, FT-IR, XRD, TGA, DTG, DCS, IRT and thermal conductivity apparatus were used and microstructure, chemical composition, crystallinity, thermal and phase-change heat transfer characteristics were investigated extensively for each sample of NePCM. The results showed good chemical and thermal stability of all NePCMs without changing the chemical structure of RT-28HC. The surface morphology and crystal formation analysis revealed the uniform dispersion of nanoparticles onto the surface of RT-28HC. In comparison of mono and hybrid NePCMs, the results showed the hybrid NePCM at GNPs/MWCTs mass percentage ratio of 75%/25% had the highest thermal conductivity enhancement of 96% compared to the pure PCM having optimum value of phase-change enthalpy of 245.18 J/g. Finally, enhancement in phase transition while melting and thermal properties evidenced that hybrid NePCMs can be used as potential candidate for the thermal management of microelectronics.
