This article explored polymeric composites and their thermal characteristics, such as their high thermal conductivity and excellent thermal stability. These characteristics are highly desired as they can be widely applied in the electronics, medical, manufacturing, etc., industries. The thermal conductivities were studied using a variety of sources, including the transient plane source (TPS). After conducting several studies on the thermally conductive polymeric composites, it was determined that there were some key scientific problems and technical difficulties that need to be solved, and further investigations must be conducted on their use.
The article investigated the hybridization of multi wall carbon nanotubes (MWCNTs) with filler in polymer matrix composites (PMC) which is one of the techniques used to combine different properties of fillers to make more unique composites. The properties of two different hybrid filler composites (Chemical Vapour Deposition (CVD) hybrid filler and physically hybrid filler) were then studied. The thermal conductivity was measured through the use of a Thermal Constant Analyzer which utilized the transient plane source (TPS) method. The phenolic composites that were filled with the CVD hybrid filler increased the thermal conductivity of the composite when compared to the physically hybrid filler.
Thermally conductive polymers are the most effective and economic methods of removing heat accumulation from microelectronics. In the present study, m-xylylenediamine (MPDA) was used as a curing agent for the epoxy matrix and analyzed for its effect on the thermal conductivity of the composite. Thermal conductivity was measured with a thermal analyzer using the transient plane source (TPS) method. When filling content of the multiwall carbon nanotubes (MWNTs) was 2%wt, thermal conductivity of the MWNTs/epoxy composite was approximately six times higher than pure epoxy resin.
This article investigates the effects of two types of nanoparticles, OctaMethylOligomericSilsesquioxanes (OMPOSS) and carbon nanotubes (CNTs), in a model epoxy resin. Intumescent phosphorous-based flame-retardant (APP) was also incorporated with the CNTs. Thermal conductivity of nanocomposites was measured using a thermal analyser with the transient plane source method. Epoxy with APP and OMPOSS had increasing thermal conductivity below the glass transition temperature (Tg) but slowed above Tg. When APP and CNTs were combined, CNTs hid the effects of APP, leading to a decrease in thermal conductivity.
