Influence of the degree of exfoliation on the thermal conductivity of polypropylene nanocomposites

This article investigated the effects of incorporating silica layers into polypropylene nanocomposites. The influence of the silica layers on the thermal conductivity of the material is compared to the influence of other fillers to determine which is superior. The authors found that particle size and number affect the thermal conductivity in addition to content percentage. The silica layers produced a more impressive increase in thermal conductivity than other fillers on ...

Thermal Conductivity of Carbon Nanofibre-Polypropylene Composite Foams

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 ...

Flame retardancy through carbon nanomaterials: carbon black, multiwall nanotubes, expanded graphite, multi-layer graphene and graphene in polypropylene

This research aims to determine the effect of altering filler particle sizes and shapes, on the thermal and mechanical properties of polypropylene (PP). Fillers such as thermally reduced graphite oxide (TRGO), multi-layer graphene (MLG250), carbon black (CB), multiwalled nanotubes (MWNT) and expanded graphite (EG), were added to the PP base. A thermal analyzer was used to measure the thermal conductivity of the various PP composites. Results determined that the PP ...

Effects of carbon fillers in thermally conductive polypropylene based resins

Researchers have determined the potential of increasing the thermal conductivity of insulating polymers by adding conductive fillers. One common application this may be used for, is fuel cell bipolar plates. In this article, researchers tested varying amounts of three different carbon fillers (black carbon, synthetic graphite particles, and carbon nanotubes), by adding them to polypropylene. Both single fillers and combination fillers were studied for their potential effects on the thermal ...
