Thermal performance enhancement of palmitic-stearic acid by adding graphene nanoplatelets and expanded graphite for thermal energy storage: A comparative study

The purpose of this study was to improve the wettability of silicon carbide (SiC) nanowires, in order for them to be used as thermoconductive fluids. Multiple experiments were conducted by exposing the SiC nanowires to hydrofluoric acid, tetraethyl orthosillicate, polyvinylpyrolidone and sodium hydroxide. Various tests, including x-ray diffraction, Fourier transformation-infrared, x-ray photoelectron spectroscopy, thermogravimetric analysis, scanning electron microscopy and transmission electron microscopy, were performed on these various materials to identify ...

RT100/expand graphite composite phase change material with excellent structure stability, photo-thermal performance and good thermal reliability

The goal of this work was to produce a new high performance PCM, using a combination of RT 100 (paraffinic hydrocarbons) with expanded graphite (EG). The resulting composite performed extremely well in quality testing. Thermal conductivity was measured using the TPS method, and was found to be much higher in the composite than it was in the basic RT 100 materials. Thermal conductivity did not decrease during melting cycles. The ability of ...

Thermally conductive phase-change materials for energy storage based on low-density polyethylene, soft Fischer-Tropsch wax and graphite 

Phase change materials (PCMs) are becoming increasingly important in the field of thermal energy storage. In this study, conductive fillers were added to wax- and polyethylene-based PCMs to improve their thermal conductivity. A Thermal Constants Analyser measured the thermal conductivity of the PCMs using the transient plane source (TPS) method. Results indicated that both nanoparticles improved thermal conductivity, but a lower concentration of expanded graphite improved conductivity more than normal ...

Experimental research on heat transfer mechanism of heat sink with composite phase change materials 

Phase change materials (PCMs) can be used as heat sinks to manage high temperature fluctuations in electronics. In this paper, a heat sink was generated from a paraffin/expanded graphite composite PCM, and the thermal conductivities of the materials were measured using the transient plane source (TPS) method of the Thermal Analyzer. Results showed that the composite PCM had a significantly higher thermal conductivity than the pure paraffin....

Preparation and thermal properties of polyethylene glycol/expanded graphite blends for energy storage

Through the addition of expanded graphite (EG) to polyethylene glycol, the authors were able to enhance the thermal conductivity of the phase change material (PCM). The transient plane source (TPS) technique was used to measure the thermal conductivity of the PCM. The amount of EG affected thermal conductivity, while amount of polyethylene glycol affected latent heat. Through the use of EG, the thermal conductivity was raised fourfold.....
