Abstract
The paper describes a method for the production of water-based nanofluids with few-layer graphene (FLG) synthesized by self-propagating high-temperature synthesis (SHS). The advantage of this method is the possibility of synthesizing large volumes of material without Stone-Wales defects at low cost. This study presents results on the viscosity, electrical conductivity, specific heat capacity, and thermal conductivity of water-based nanofluids modified with FLG. By using 0.8 mass % FLG obtained by SHS, it became possible to obtain stable nanofluids without the use of surfactants. The FLG concentration of 0.8 mass % increased thermal conductivity by up to 2.3 times and electrical conductivity by up to 90 times compared to pure water at 60 °C. At the same time, there were no significant changes in the viscosity or heat capacity of the nanofluids at different FLG concentrations and temperatures.
期刊介绍:
The journal Carbon is an international multidisciplinary forum for communicating scientific advances in the field of carbon materials. It reports new findings related to the formation, structure, properties, behaviors, and technological applications of carbons. Carbons are a broad class of ordered or disordered solid phases composed primarily of elemental carbon, including but not limited to carbon black, carbon fibers and filaments, carbon nanotubes, diamond and diamond-like carbon, fullerenes, glassy carbon, graphite, graphene, graphene-oxide, porous carbons, pyrolytic carbon, and other sp2 and non-sp2 hybridized carbon systems. Carbon is the companion title to the open access journal Carbon Trends. Relevant application areas for carbon materials include biology and medicine, catalysis, electronic, optoelectronic, spintronic, high-frequency, and photonic devices, energy storage and conversion systems, environmental applications and water treatment, smart materials and systems, and structural and thermal applications.
