“…16d). The percolation threshold is determined by a sharp drop of electrical resistance and it depends on the size and shape (aspect ratio) of fillers [308,[317][318][319], their dispersion [317,320,321], interfacial interactions, and alignment [322][323][324].…”

Composite materials and especially polymer composites are widely used in daily life and different industries due to their vastly different properties and design flexibility. It is known that the properties of the composites are strongly related to the properties of its constituents. However, it has been reported in many studies, experimentally and by simulations, that the characteristics of the composites do not follow the rule of mixing. It means that in addition to properties of the constituents, there are other parameters affecting the final physicochemical properties of composites. The interfacial interactions between fillers and host is one of the factors which can strongly affect the properties of the composite. In this review, we summarized the type of interactions between the constituents, their improvement techniques, interaction measurement methods, and the effects of interfacial interactions on thermal, mechanical, and electrical properties of composites.

“…However, metallic particle fillers have several disadvantages compared with fibre filler such as higher density and greater susceptibility to oxidation. Figure 5 summarizes the thermal conductivities for various particle-enhanced polymer composites 16,18 with filler content of 10% and 30%. It is clear that by changing the filler content from 10% to 30%, the thermal conductivity of polymer composites increases about 1.5 to 2.5 times.…”

Due to their low cost, light weight and corrosive resistant features, polymer heat exchangers have been intensively studied by researchers with the aim to replace metallic heat exchangers in a wide range of applications. This paper reviews the development of polymer heat exchangers in the last decade, including cutting edge materials characteristics, heat transfer enhancement methods of polymer materials and a wide range of polymer heat exchanger applications. Theoretical modelling and experimental testing results have been reviewed and compared with literature. A recent development, the polymer micro-hollow fibre heat exchanger, is introduced and described. It is shown that polymer materials do hold promise for use in the construction of heat exchangers in many applications, but that a considerable amount of research is still required into material properties, thermal performance and life-time behaviour.

“…However, these models do not consider the effect of percolation path formation. As the volume content ratio increases, the actual thermal conductivity of the composite material becomes higher than the value predicted using these models Soga, Saito, Kawaguchi and Satoh, Journal of Thermal Science and Technology, Vol.12, No.1 (2017) (Kumlutas and Tavman 2006, Hill and Supanic, 2002and Mamunya et al, 2002. The use of numerical simulations such as the finite element method (FEM) is beneficial in predicting the thermal conductivity including the percolation effect (Kumlutas andTavman, 2006 andStrader, 2007).…”

Polymers containing ceramics filler are used in various fields that require good thermal conductivity and electric insulation. For material design, prediction of the thermal conductivity is thus critical. There are several prediction methods to determine the thermal conductivity of filler-dispersed composites, such as the Hatta-Taya and Bruggeman models. However, these models do not consider the effect of interaction between fillers; thus, the actual thermal conductivity is larger than the predicted thermal conductivity. In this research, the thermal conductivity of polymers containing ceramic filler was numerically simulated, and the results were compared with the values predicted using the Hatta-Taya model to investigate the effect of filler orientation angle and aspect ratio. The trend of the thermal conductivity change was similar to that observed for the Hatta-Taya model, however, the simulated thermal conductivities were 30% larger than those determined using the Hatta-Taya model for a filler thermal conductivity and volume content of 40 W/(mK) and 25%, respectively. The simulated thermal conductivity results prominently deviated from the Hatta-Taya model values when the filler content ratio was large, the filler aspect ratio was small, or the filler orientation was along the heat-transfer direction.
