“…electrical conductivity as compared to those prepared using other techniques. The electrical and thermal properties of carbon nanomaterial/polymer composites are widely described using percolation theory, though the term "thermal percolation" is still a subject of debate [74,75]. In the case of electrical percolation, at very low filler loadings, the conductivities remain very close to the insulating pure polymers since the fillers are in a random arrangement.…”

Graphene is the newest member of the carbon family, and has revolutionized materials science especially in the field of polymer nanocomposites. However, agglomeration and uniform dispersion remains an Achilles" heel (even an elephant in the room), hampering the optimization of this material for practical applications. Chemical functionalization of graphene can overcome these hurdles but is often rather disruptive to the extended piconjugation, altering the desired physical and electronic properties. Employing surfactants as stabilizing agents in latex technology circumvents the need for chemical modification allowing for the formation of nanocomposites with retained graphene properties. This article reviews the recent progress in the use of surfactants and polymers to prepare graphene/polymer nanocomposites via latex technology. Of special interest here are surfactant structure-performance relationships, as well as background on the roles surfactantgraphene interactions for promoting stabilization.

“…12,13 CNTs have a unique one-dimensional structure that enables the composites filled with CNTs to have low percolation threshold concentrations. 14,15 Due to these characteristics, composites filled with CNTs show the enhancement of thermal conductivity even at low concentrations. 16,17 Fan et al reported a significant effect of the alignment of CNTs on thermal conductivity.…”

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.

“…For example, a small difference in operating temperature in the order of 10~15 o C can result in a two-fold reduction in the life time of the electronic devices [24]. CNT has the one-dimensional unique structure which enables the composites filled with CNT to have low percolation threshold concentrations [25,26]. By using this characteristics, CNT incorporated composites show the thermal conductivity enhancement at low concentrations [27,28].…”

Recently, the use of thermal conductive polymeric composites is growing up, where the polymers filled with the thermally conductive fillers effectively dissipate heat generated from electronic components. Therefore, the management of heat is directly related to the lifetime of electronic devices. For the purpose of the improvement of thermal conductivity of composites, fillers with excellent thermally conductive behavior are commonly used. Thermally conductive particles filled polymer composites have advantages due to their easy processibility, low cost, and durability to the corrosion. Especially, carbon-based 1-dimensional nanomaterials such as carbon nanotube (CNT) and carbon nanofiber (CNF) have gained much attention for their excellent thermal conductivity, corrosion resistance and low thermal expansion coefficient than the metals. This paper aims to review the research trends in the improvement of thermal conductivity of the carbon-based materials filled polymer composites.
