Researchers in this study aimed to develop polymer composites with high thermal conductivity, using polystyrene (PS) and multi-walled carbon nanotubes (MWNTs). These composites were prepared by ultrasonic radiation, through a simple-solution-evaporation method. Poly(styrene-co-maleic anhydride) (PSMA), with a benzene group and experiencing a strong affinity for PS was used as a base, to allow the MWNTs to be dispersed within the composite (MWNT-g-SMA). Results determined that the addition of MWNTs ...

Using a solid hot stretching technique, highly-oriented polyoxymethyelen (POM)/multi-walled carbon nanotubes (MWCNTs) composites were created. Thermal properties were analyzed both in the stretched and through-plane directions. Researchers found that by increasing the draw ratio, to as high as 900%, the thermal conductivity of the composite has improved in the stretching direction, when compared to the material prior to this process. Researchers also determined that the thermal conductivity of the MWCNTs ...

A novel technique was used in this research article, to introduce a hybrid mesh to a polymer composite within bipolar plates, for proton exchange membrane fuel cells (PEMFCs). The mesh added was copper or aluminum based, to allow for an increased thermal conductivity of the PEMFCs. Experimental testing confirms this theory, as the copper-meshed hybrid polymer composite showed a thermal conductivity of 30.0 W/mK, while the aluminum-meshed hybrid polymer composite ...

The Transient Plane Source method was used in this research article to measure the thermal conductivity of an Ionanofluid, highly stable graphene (GE)-based nanofluid, at various temperatures. Researchers took special note of the effects of temperature, GE loading, presence of multi-walled carbon nanotubes (MWCNTs), on the thermal conductivity of the nanofluid. Through experimental testing, it was determined that the nanofluid elicited a higher thermal conductivity, as compared to its ...

In this paper, researchers investigated the effects of multi-walled carbon nanotubes (MWNTs), on the thermal conductivity and phase change enthalpy of palmitic acid (PA), a solid to liquid phase change material. The research concluded that as the concentration of MWNTs is increased, the thermal conductivity of the composite increases, compared to that of PA alone. Also in this study, researchers investigated the effects of various MWNTs surface modifications, on the ...
