This paper focused on determining the thermal conductivity of multiwalled carbon nanotubes (MWCNTs) and carbon nanofibers (CNFs) that were dispersed throughout n-octadecane as phase change materials (PCMs). The Thermal Constants Analyzer TPS measured the thermal conductivity of the n-octadecane samples at solid and liquid phases using the transient plane source (TPS) method. Results showed that the thermal conductivity of the solid phase n¬-octadecane/MWCNTs samples increased with nanotube concentration. ...
The present study look at the creation of unfilled and carbon nanofibre (CNF)-filled polypropylene (PP) foams, and their subsequent testing of thermal and mechanical properties. The testing of thermal properties was accomplished by the TPS Technique and determined that when using up to 20 wt.% CNF as filler there was no increase in thermal conductivity of any of the sample foams. Therefore it was decided that it was the foamed ...
The main objective of this research project was to create a material with a very low thermal conductivity at high temperatures, for the conservation of energy in high temperature systems. To accomplish this goal, the researchers incorporated carbon nanofibers into the mesoporous network of monolithic aerogels, with up to a 20 wt.% through an accelerated-gelation sol-gel process. The synthesis process also involved the use of supercritical drying of the aerogels to ...
