“…The PNCs have attracted great attention due to their drastically enhanced properties [3][4][5]. For instance, thermally insulating polymers can be transformed into thermal conductors after reinforcing with carbon nanotubes (CNTs) [6][7][8]. Moreover, PNCs have demonstrated improved mechanical, gas barrier, solvent resistance, and flammability properties compared to the corresponding neat matrices [3,4,9].…”

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.

“…When CNTs were aligned in a single direction, the composite material exhibited much increased thermal conductivity. 18 The length effect of CNTs has also been explored. If the CNTs were too long, the CNTs coiled within the polymer matrix and the CNTs could not efficiently transfer the heat in the matrix.…”

In order to enhance the thermal conductivity of poly(dimethyl siloxane) (PDMS), boron nitride (BN) and carbon nanotubes (CNTs) were incorporated as the thermally conductive fillers. The amount of BN was increased from 0 to 100 phr (parts per hundred rubber) and the amount of CNTs was increased from 0 to 4 phr at a fixed amount of the boron nitride (100 phr). The thermal conductivity of the composites increased with an increasing concentration of BN, but the incorporation of CNTs had only a slight effect on the enhancement of thermal conductivity. Unexpectedly, the thermal degradation of the composites was accelerated by the addition of CNTs in 100 phr BN filled PDMS. Activation energy for thermal decomposition of the composites was calculated using the Horowitz-Metzger method. The curing behavior, electrical resistivity, and mechanical properties of PDMS filled with BN and CNTs were investigated.

“…1 To make the best of the high thermal conductivity (more than 3000 W/mK) 2,3 of CNTs, the effects of some structure factors of CNTs such as the dispersion, morphology and size on the properties of CNT/epoxy composites have become a hot topic. [4][5][6][7][8][9][10][35][36][37] Yang 11 explored the effect of the dispersion of CNTs on the thermal conductivity of carbon nanotube/epoxy composites (kc) by functionalizing CNTs. The result shows that the k c of the sample containing functionalized CNTs can be enhanced by 67%-103% at a loading of 1 vol % -5 vol % compared with the k c of the sample containing pristine CNTs because of the good dispersion and the lower C sm (interfacial thermal conductance between the CNTs and epoxy matrix).…”

The structure factors of carbon nanotubes such as the dispersion, morphology and size have effects on the thermal conductivity of carbon nanotube/epoxy composites (kc). However, the behavior how these structure factors affect the kc has still not been fully understood. To seek the answer, three-dimensional computational models containing various dispersion of bending single wall carbon nanotubes (SWCNTs) are developed using the finite element method. A conjecture is proposed based on these models that the dispersion and the number of the overlapping heat-affected zones (OHAZs) of heat conduction networks play an important role on the kc. To prove the conjecture, a feature parameter–a dispersion coefficient is proposed to quantify the dispersion uniformity. The kc is calculated in models with different dispersion coefficients. The results show that the kc increases with the dispersion coefficient. The effects of the morphology and the size of SWCNTs on the kc could also be explained using this conjecture. SWCNTs with a larger length efficiency and diameter are found to be beneficial to a higher kc. Because a larger length efficiency increases the number of OHAZs and a larger diameter SWCNT has a wider heat-affected zone which also increases the number of OHAZs.
