Study on consolidated composite sorbents impregnated with LiCl for thermal energy storage

In this study, a new type of sorption process was developed using activated carbon (AC) as a porous host to carry LiCl. A silica solution (SS) and expanded natural graphite treated with sulfuric acid (ENG-TSA) were added to increase heat transfer and mechanical strength of the composite. Thermal conductivities of the samples were measured using the Transient Plane Source (TPS) technique. Results found higher thermal conductivities directly correlated to larger ...

Enhanced comprehensive performance of polyethylene glycol based phase change material with hybrid graphene nanomaterials for thermal energy storage

In this study, high performance composite phase change materials (PCMs) were created. Graphene oxide (GO) nanosheets were used as supporting materials to keep the shape of polyethylene glycol (PEG) stable during phase change, and graphene nanoplatelets (GNP) were used as conductive fillers. Thermal conductivity was measured with a transient plane source method. Thermal conductivity was found to increase linearly with GNP loading, and PEG/GO/GNP composite PCMs exhibited higher ...

Strategy for visualisation of the activity of phase change materials by transient plane source technique

Phase change materials (PCMs) are materials that store thermal energy and undergo phase transitions when they are heated and cooled, making them effective alternatives to fossil fuels for building insulation. To determine the energy performance of PCMs in infrastructure it is important to understand their thermal characteristics. The transient plane heat source (TPS) method was used to determine the thermal conductivity of the PCMs ClemSel 21 and ClemSel 24. The thermal conductivities ...

Polymer encapsulated paraffin wax to be used as phase change material for energy storage

In this thesis study, the sensor was used to characterize polymer encapsulated paraffin waxes as phase change materials (PCM). The main purpose of this study was to determine the effect of the polystyrene (PS) and PS: wax microcapsules on the morphology and thermal, mechanical and conductivity properties of the polypropylene matrix. Post-melting, the PP microcapsules were extremely well dispersed within the matrix and there was a strong interaction between them ...


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 ...
