“…This characteristic of EO composites is in contrast to vulcanized elastomer composites, which typically exhibit a decrease in elongation if filled with moderate amounts of high structure carbon black. 24,25 The most widely used models for the change in modulus of a filled elastomer are the Guth hydrodynamic models. 26 The model for spherical reinforcing particles with perfect adhesion has the form…”

ABSTRACT:Composites that incorporate a conductive filler into an ethylene-octene (EO) elastomer matrix were evaluated for DC electrical and mechanical properties. Comparing three types of fillers (carbon fiber, low structure carbon black, and high structure carbon black), it was found that the composite with high structure carbon black exhibited a combination of properties not generally achievable with this type of filler in an elastomeric matrix. A decrease in resistivity at low strains is unusual and has only been reported previously in a few instances. Reversibility in the resistivity upon cyclic deformation is a particularly unusual feature of EO with high structure carbon black. The mechanical and electrical performance of the high structure carbon black composites at high strains was also impressive. Mechanical reinforcement in accordance with the Guth model attested to good particle-matrix adhesion. The EO matrix also produced composites that retained the inherent high elongation of the unfilled elastomer even with the maximum amount of filler (30% by volume). The EO matrix with other conducting fillers did not exhibit the exceptional properties of EO with high structure carbon black. Composites with carbon fiber and low structure carbon black did not maintain good mechanical properties, generally exhibited an increase in resistivity with strain, and exhibited irreversible changes in both mechanical and electrical properties after extension to even low strains. An explanation of the unusual properties of EO with high structure carbon black required unique features of both filler and the matrix. The proposed model incorporates the multifunctional physical crosslinks of the EO matrix and dynamic filler-matrix bonds.

“…Most of these studies, however, concentrated on the time-and rate-dependent behavior of unfilled TPEs at ambient temperature. Only a few works dealt with the viscoelastic and viscoplastic responses of thermoplastic elastomers reinforced with carbon black (Kurian et al, 1995;Datta et al, 1996;Katbab et al, 2000;Yamauchi et al, 2005), and none of them investigated mechanical properties at elevated temperatures. From the viewpoint of fundamental research, the objectives of the present study are (i) to report observations in uniaxial tensile tests with finite strains on a carbon black-reinforced TPE in a relatively large range of temperatures, and (ii) to analyze the effects of temperature and strain rate on adjustable parameters in the stress-strain relations.…”

Hollow carbon black (HCB) is introduced in this work. It has a special hollow structure, high specific surface area, high structure and high electric conductivity. Hollow carbon black is used to fill styrene-butadiene rubber (SBR). The bound rubber test results show that the bound rubber of SBR/HCB can be measured when the HCB content reaches 25 phr because a strong filler network is formed, which indicates good electric conductivity of SBR/HCB. In comparison, the bound rubber of SBR/N330 can not be measured even when the N330 content is 40 phr. The mechanical measurements show that HCB has very good reinforcing effect on SBR especially when the filler content is low. The electric conductivity and thermal conductivity increase with the increase in filler content. At the same filler content, the properties of SBR/HCB nanocomposites are better than those of SBR/N330 nanocomposites, which suggests that HCB has good application potential.
