Synthetic polymers in starch-based polymer formulations improve the thermal and mechanical properties of the compounds. The purpose of this study was to develop and analyze foams containing ethylene-vinyl acetate (EVA) and varying concentrations of corn starch. A Thermal Constants Analyser measured the thermal conductivity of the EVA/starch samples using the transient plane source (TPS) method. Results showed that the thermal conductivity of the blends increased with starch content. The ...
Polypropylene (PP) foams are commercially manufactured in four ways, with each method producing different characteristics. The aim of this paper was to examine the properties of each PP-based foam and compare their thermal behaviors and conductivities. A thermal constant analyzer was used to measure the thermal conductivity of the foam samples with the transient plane source (TPS) technique. Results showed that thermal conductivity varied for each production method, but density ...
Minerals are often added to polypropylene (PP) foams to improve thermal conductivity. The aim of this study was to test and compare the thermal conductivity of unfilled, magnesium hydroxide (Mg(OH)2)-, and montmorillonite (MMT)-reinforced PP foams. An analyzer measured the thermal conductivity of the polypropylene foams using the Transient Plane Source (TPS) method. Results showed that thermal conductivity increased with foam density and with magnesium concentration....
The authors report the synthesis of a novel functionalized graphene sheet (FGS)/silicone porous nanocomposite with varying concentrations of FGS. The physical and thermal properties of the synthesized nanocomposites were studied in depth. SEM and TEM were used to elucidate the physical microstructure of the materials, and the transient plane source (TPS) technique was used to measure thermal conductivity. The nanocomposite showed an increased thermal conductivity as compared to the ...
The present study used the transient plane source (TPS) technique to measure the thermal conductivity of a series of AlSi7 metal foams prepared by the powder metallurgical route. The main difference between the different foam samples was their density, which led to a change in thermal conductivity. In addition to measuring thermal conductivity, the TPS sensor was used to detect in-homogeneities by placing it on each face of a cube ...
