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.}, keywords = {graphene oxide,Ethylene-glycol,Thermal conductivity,Reduce,concentration}, url = {https://www.physchemres.org/article_14777.html}, eprint = {https://www.physchemres.org/article_14777_becb56bea96f71353f7af494d696ccc1.pdf} }
