“…It has been observed that suspended cellulose nanocrystals exhibit a tendency to align themselves, probably due to their high solidity and length-to-diameter ratio [30] . It is also very important to determine whether the cellulose nanocrystals are well dispersed in suspension, because this is required to achieve good results when they are incorporated in a polymeric matrix for mechanical reinforcement [43,44] .

“…Lee et al [24] and Göldel et al [25] studied the electrical properties of melt extruded SAN/MWCNT nanocomposites and found !4·10 -4 and !1·10 -4 S/cm at 2 and 1.5 wt% MWCNT loadings, respectively. A DC conductivity of !10 -2 S/cm at 15 wt% of CNT loading in poly (styrene-co-butyl acrylate)/MWCNT nanocomposites was reported by Dufresne et al [26]. Singh et al [27] reported an electrical conductivity value of !1.27·10 -6 S/cm in (80/20 w/w) ABS/PS blend at 0.64 wt% MWCNT loading.…”

Compared to the pure HIPS, a higher Shrivastava et al -eXPRESS Polymer Letters Vol.8, No.1 (2014) [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] conductivity is observed in the nanocomposites with increasing wt% of CNT loading. With an increase in CNT loading from 0~0.6 wt%, a sharp increase in conductivity was found in the low frequency region.…”

Abstract. This work demonstrates a simple method to develop highly conducting high impact polystyrene (HIPS)/multiwall carbon nanotube (MWCNT) nanocomposites through selective dispersion of MWCNT in HIPS matrix. The method involves in-situ polymerization of polybutadiene containing styrene monomer in the presence of HIPS beads and MWCNT. A significantly lower percolation threshold value than ever reported for HIPS/MWCNT systems was obtained using unmodified unaligned MWCNTs. With the increase in HIPS bead content (at a particular MWCNT loading) in the HIPS/MWCNT nanocomposites, the conductivity value was increased, suggesting that the presence of HIPS beads acted as excluded volume that decreased the percolation threshold. An increase in electrical conductivity from 1.91·10 -7 to 1.15·10 -5 S/cm was evident, when the HIPS bead content was increased from 30 to 60 wt% at a constant loading of MWCNT (i.e. 0.6 wt%). The morphological investigation of the HIPS/MWCNT nanocomposites revealed that, the MWCNTs were selectively dispersed in the in-situ polymerized HIPS region, outside the HIPS beads, which resulted in the lowering of the percolation threshold to a lower value of 0.54 wt%. The morphology and electrical properties of the nanocomposites have been discussed in detail in the manuscript.

“…Significant efforts have been made to uniformly disperse and align CNTs in the matrix. [19][20][21][22][23] For well-dispersed and aligned CNTs that are perfectly bonded to the matrix, the theoretical and computational models predict superior properties of CNT-reinforced composites. [24][25][26][27][28] However, extensive experiments on CNT-reinforced composites 20,[29][30][31][32][33][34] show some improved properties, but many fall short to reach the theoretical predictions.…”

The interface behavior may significantly influence the mechanical properties of carbon nanotube (CNT)-reinforced composites due to the large interface area per unit volume at the composite. The modeling of CNT/polymer interfaces has been a challenge in the continuum modeling of CNTreinforced composites. This paper presents a review of recent progress to model the CNT/matrix interfaces via a cohesive law established from the van der Waals force. A simple, analytical cohesive law is obtained from the interatomic potential, and is used to study the effect of CNT/matrix interfaces on the macroscopic properties of CNT-reinforced composites.
