Thermal Conductivity of Reduced Graphene Oxide by Pulse Laser in Ethylene Glycol
Authors
Abstract:
Graphene oxide was prepared using modified Hummers method. Stable ethylene-glycol nanofluids containing graphene oxide nanosheets were provided. Nd: YAG pulsed laser was applied to prepare reduced nanofluids. Experimental results revealed that thermal conductivity of the nanofluids is increased with increasing the concentration of graphene oxide (GO) in ethylene glycol. The enhancement ratio of 0.05% mass fraction of GO was 16.32%. Thermal conductivity improved with increasing the temperature about 14.28%. The dynamic light scattering and results of zeta potential analyses, after one week and eight months, showed the same results which demonstrated the stability of nanofluids.

and the cross-plane thermal conductivity K ⊥ ≈ 20 W m −1 K −1 at room temperature (RT). [ 2,3 ] Despite its large K and K / K ⊥ ≈ 100, unprocessed graphite cannot be used for thermal management because it does not meet industry requirements, e.g., fl exibility. The commercial thermal pads based on composites with chemically processed graphite have lower K and smaller K / K ⊥ ratios. These consi...
full textEnhanced conductivity of reduced graphene oxide decorated with aluminium oxide nanoparticles by oxygen annealing.
A process involving the filtration of graphene oxide (GO) dispersion through an alumina membrane, followed by oxygen annealing to synthesize alumina nanoparticles exclusively at the edges of holes or vacancies in the reduced graphene oxide (rGO) plane, is used to prepare paper-like composites with a 21% enhanced electrical conductivity. Moreover, the rGO/alumina nanocomposites have a smaller ba...
