Characteristic analysis of three-ecofriendly reduced graphene oxides (rGOs) and their application in water–ethanol-based fluids with different volume ratios

Abstract

Three ecofriendly reduced graphene oxides (rGOs) and rGO nanofluids with different water–ethanol volume ratios were prepared. The microstructure of rGO and the stability, thermal conductivity and contact angle of rGO nanofluids were investigated.
