Investigation of the Thermal Conductivity and the Viscosity of Carbon Black Heat Transfer Nanofluids

Seven distinct samples of nanofluids consisting of different concentrations of spherical graphitized carbon black in an ethylene glycol solution were analyzed to determine their thermal and rheological behavior. The thermal conductivity measurements were made at 20°C and 30°C with a transient hot wire instrument made by Thermtest called THW-L2 and specifically designed to measure the thermal conductivity of liquids. This study was ...

Nano-PCMs for enhanced energy storage and passive cooling applications

Phase change materials (PCMs) are substances that release large amounts of energy in the form of latent heat when they freeze. Paraffin waxes have many of the desired characteristics PCMs exhibit except that they have low thermal conductivity. In this experiment, Alumina and Carbon Black nanoparticles were added to two types of paraffin waxes (melting points of 20-25 °C) to increase their thermal conductivity. A Transient Plane Source (TPS) measured ...

A Study of Carbonized Lignin as an Alternative to Carbon Black

The properties of carbonized lignin nanoparticles were investigated to determine if this material could be used as an environmentally-friendly alternative to carbon black. The observed surface area of the carbonized lignin was found to be higher than that of carbon black because the powder is highly porous. The lignin nanoparticles were able to be produced in such a way as to give a similar size as carbon black nanoparticles, with ...

Toward lithium ion batteries with enhanced thermal conductivity

Li-ion battery electrodes are typically mixed with carbon black materials which have low thermal conductivity in high-power-density battery applications. In this study, multi-walled carbon nanotubes (MWCNTs) were added to Li-ion battery electrodes to improve thermal conductivity. A measured the thermal conductivity of the electrode samples at room temperature using the transient plane source (TPS) method. Results showed that the addition of MWCNTs enhanced the thermal conductivity of the electrodes by ...

Flame retardancy through carbon nanomaterials: carbon black, multiwall nanotubes, expanded graphite, multi-layer graphene and graphene in polypropylene

This research aims to determine the effect of altering filler particle sizes and shapes, on the thermal and mechanical properties of polypropylene (PP). Fillers such as thermally reduced graphite oxide (TRGO), multi-layer graphene (MLG250), carbon black (CB), multiwalled nanotubes (MWNT) and expanded graphite (EG), were added to the PP base. A thermal analyzer was used to measure the thermal conductivity of the various PP composites. Results determined that the PP ...
