Intercomparison of Measurements of the Thermophysical Properties of Polymethyl Methacrylate

The variability within the results presented from the guarded hot-plate (GHP) and guarded heat-flow meter (GHF) methods was determined. Multiple thermal properties of polymethyl methacrylate (PMMA) were analyzed to compare methods. These measurements are taken in the range of −70◦C and +80◦C. Providing reference data for PMMA is the main objective of this paper as well as quantifying the effects of thermal contact of the measuring instruments....

Thermal Characterization of Lauric–Stearic Acid/Expanded Graphite Eutectic Mixture as Phase Change Materials

Expanded graphite (EG) was added to lauric acid (LA)-stearic acid (SA) phase change materials to enhance their thermal conductivities. The PCMs were prepared in varying mass fractions of LA and SA, and 10 wt. % of EG was added. The phase change temperature and phase change enthalpy were determined by DSC, while the thermal conductivities, and thermal stabilities of the PCMs were determined by the transient plane source and thermogravimetric analysis, ...

Preparation of low-density polyethylene/low-temperature expandable graphite composites with high thermal conductivity by an in situ expansion melt blending process

Low-temperature expandable graphite (LTEG) was blended into low-density polyethylene (LDPE) to prepare composite materials with an enhanced thermal conductivity in comparison to pure LDPE. The thermal conductivity of a composite containing 60 wt. % LTEG was found to be increased by a factor of 23 in comparison to the pure polymer. The LTEG was also found to decrease the melting temperature and degree of crystallinity of the LDPE, and the composites were also ...

Thermal Composites of Biobased Polyamide with Boron Nitride Micro Networks

In this paper, polyamide (PA, composed of at least 60% renewable materials) was used as a polymer matrix to prepare PA-hexagonal boron nitride (hBN) polymer composites with varying hBN contents. Two different PA samples were used in this study: a low viscosity grade PA (PA-30), as well as a high viscosity grade PA (PA-90). The composite polymers were tested to evaluate their thermal, physical, and mechanical properties. It was concluded that ...

Silver incorporated microencapsulation of n-hexadecane andn-octadecane appropriate for dynamic thermal management in textiles

In this paper, the authors discuss the preparation of microencapsulated phase change materials (PCMs). The PCMs used in this study were n-hexadecane and n-octadecane, and the shell was made up of poly(urea-formaldehyde). The effect of dispersing silver nanoparticles in the shells on the thermal storage properties of these encapsulated PCMs was also investigated. The enthalpies of fusion of the samples were determined experimentally, as was the thermal conductivity. It ...
