Control of Percolation Behavior Through Nanoparticle Induced Network Self-Assembly in Polymer-Carbon Nanotube Composites

摘要

In a previous study, we discovered that if carbon black nanoparticles (CB) are incorporated into a polymer matrix together with an optimum concentration of organoclay nanoparticles (nanoclay), percolation becomes sudden and the threshold shifts to a low CB content while the slope is reduced. This was found to be a direct result of nanoclay enhanced long range percolating conductive network. In this paper, we will present our first results on the influence of nanoclay and carbon nanotube concentrations on the electrical conductivity of compression molded as well as injection molded parts.
