Abstract

Super-growth single wall carbon nanotube (SG-SWNT) offers several unique aspects such as high aspect ratio, high purity and high surface area, etc. When subjected to jet-milling, SG-SWNT forms a dendric-network, imparting unique properties to CNT-based conductive elastomers. It is observed that the SG-SWNT dendric-network traverses the entire dimension of the composite uniformly, as opposed to HiPCO-SWNT-which is found to form isolated, globular islands. This difference in the percolation and distribution of SG-SWNT in the elastomer is reflected in its largely invariant conductivity under strain, in contrast to HiPCO-SWNT based elastomer which shows a steady degradation of the conductivity under similar strain. Thus, a composite made by combining jet-milled SG-SWNT with fluorinated rubber exhibits minimal change in conductivity with repeated stretching. The intrinsic ability of dendric SG-SWNT network to withstand strain without losing the entanglement is critical for the observed invariance in conductivity of the SG-SWNT/fluorinated rubber composite.
