Abstract: In the current study, the thermal conductivity of paraffin wax (PW) have been investigated via various parameters. The first variable was the relative concentrations and contents of the nano additives of Multi-Walled Carbon Nanotubes (MWCN), forming nano composites Phase Change Materials (PCM). The second variable is the diameter of these MWCN ranging from 10 nm to 100 nm. The paraffin/MWCNTs composite PCMs have been tailor-made for further applications in producing Thermal Energy Storage (TES). For the purpose of selecting an optimum atomic structure as the supporting matrix for the new composite PCM. It was shown that the diatomite material calcined at 600 °C for 2 h has the best pozzolanic reactivity and comparable paraffin absorption capacity compared to other diatomite candidates. It, therefore, was used as the supporting matrix of the new paraffin/diatomite/MWCNTs composite PCM. The thermal properties of this fabricated composite PCM were determined by the DSC (differential scanning calorimetry) method. In addition, the experimental results from FTIR (Fourier transform infrared) and TGA (thermogravimetric analysis) on this composite PCM showed that it has good chemical compatibility and thermal stability. Moreover, compared to the pure paraffin, the paraffin/CMWNTs composites PCM, the use of MWCNTs was found to have clear beneficial effects for improving the thermal conductivity and heat storage/release rates. Several experimental techniques have been employed to characterise the prepared composites of paraffin/MWCNTs, such as SEM to evaluate the physical appearance at nanoscale of the prepared composites, XRD to examine the contents and the crystal structure of the pure and doped materials. Further investigations are required to study the durability of these composites considering the number of possible circles (heating/cooling) applications and any degrading over time.

Abstract: Water vapor adsorption characteristics onto silica gel has been investigated for its suitability for advanced applications. Porous structure of silica-gel of a few nanometer diameter sizes provides high surface area for adsorption process. Doping silica-gel based materials with Multi-walled Carbon Nanotubes (MWCNTs) have been studied in some details. Adsorption is essentially a surface phenomenon. Absorption and Adsorption are quite different concepts. While absorption means uniform distribution of the substance throughout the bulk, adsorption means distribution of the substance at the surface of the bulk. Based on this fact, the serface structures and the homogeneity at the 3D of the prepared composites have been examined using SEM (Scanning Electron Microscopy). Raman spectroscopy has been used to investigate the optical scattering properties of the pristine silica-gel and the doped one with MWCNTs. Where the obtained spectra have been analysed based on the effect of the percentage weights of the dopants on the amorphous scattering bands of the base material. The thermal properties of the composites were determined by the DSC (differential scanning calorimetry) method. The study of the water adsorption characteristics onto the silica gel doped with MWCNTs adsorbent is highly important because of its technological applications such as cooling chillers, and water desalination, which is translated to cost. Hence, further experimental and theoretical research are needed to study the effect of water vapor adsorption onto doped silica gel with MWCNTs at different temperatures and pressures, and to interpret the obtained results based on the available theoretical models.
