“…13 Different polymer/CNTs nanocomposites have been synthesized by incorporating CNTs into various polymer matrices, such as polyamides, 14 polyimides, [15][16][17] epoxy, 18 polyurethane, 19,20 polypropylene, [21][22][23] and PVC. 11 The rheological behavior of polymer nanocomposites as a function of filler content is of great importance in polymer processing, particularly for the analysis and design of processing operations, as well as understanding structure property relationships of polymer nanocomposites. The rheological behavior can realize the full potential of CNTs for application in thermoplastic matrix-based polymer nanocomposites and to optimize the processing conditions for achieving high performance polymer nanocomposites.…”

“…These properties make CNTs as a promising candidate for producing CNTs/polymer nanocomposities with multifunctional features. [9][10][11][12] The performance properties of these types of composite can be related to the degree of association with the polymer, depending strongly on the composition of the CNTs, as determined by its nature. 13 Different polymer/CNTs nanocomposites have been synthesized by incorporating CNTs into various polymer matrices, such as polyamides, 14 polyimides, [15][16][17] epoxy, 18 polyurethane, 19,20 polypropylene, [21][22][23] and PVC.…”

Polymer nanocomposites consisting of single-walled carbon nanotubes (SWCNTs) and poly(vinyl chloride) were prepared by casting technique. The complex viscosity increased with increasing SWCNTs content, and it had a percolation concentration threshold equal to 0.45 wt % of SWCNTs. The storage modulus, G 0 , increased with increasing either SWCNTs content or frequency. A gradual decrease in the terminal zone slope of G 0 for the nanocomposites with increasing SWCNTs content may be explained by the fact that the nanotube-nanotube interactions will be dominant at higher CNTs content, and lead to the formation of the interconnected or network-like structures of SWCNTs in the polymer nanocomposites. The rheological loss factor indicates two relaxation peaks at frequencies of 0.11 and 12.8 Hz due to the interaction between SWCNTs and polymer chains and glass transition, respectively. Dynamic mechanical properties were measured for the prepared composites. The results indicate that the storage modulus changes steadily, and the tand peaks are less intense for high SWCNTs content. Tensile tests were measured and depicted by an increase in the elastic modulus with increasing SWCNTs content, but it decreases for all composites as the testing temperature increased.

“…13) demonstrate that the first effect is predominant at low filler concentrations ( < c ). Then, increase of the MWCNT content at  > c leads to prevalence of the second effect, and we can observe increase of the thermal conductivity due to additional heat transfer through the filler phase (Mamunya et al, 2008).…”

“…The state-of-the-art development in the field is described in a recent review [20]. The increase in TC of a polymer composite by addition of CNTs was found to be either marginal [21], or small, up to 125% [22]. Theory predicts a highest thermal conductivity for ideal SWNTs, therefore, one would anticipate, for composites with ideal SWNTs as a filler.…”

Abstract:A weak thermal conductivity (TC) of a polymer can be modified by inclusion of nanoparticles with high TC. Here we study the TC enhancement in epoxy resin (ER) based composites by incorporation of carbon nanotubes (CNTs) and demonstrate that the enhancement depends critically on the alignment of CNTs. The highest effect in TC enhancement (18.9) was obtained in ER with vertically aligned multiwall CNTs (VANTs) and in ER with horizontally aligned nanotubes (HANTs) (6.5). We analyze the influence of intrinsic structural factors of CNTs as well as extrinsic factors limiting the enhancement of the composite TC. The dynamics of heat propagation in ER/VANT, a strongly anisotropic and heterogeneous system, was studied experimentally, using laser flash apparatus (LFA), and by computer simulation, applying a coaxial cylinder model. It was found that the thermal resistivity CNT-ER interface to be a key extrinsic factor limiting the dynamics of the heat propagation. We show that these dynamics and the interface resistivity can be efficiently studied using the LFA technique.
