Abstract

By using a latex-based technology, it is possible to homogeneously disperse single and multi wall carbon nanotubes (NTs) within most of the polymers that are produced by emulsion polymerization, or that can be brought into the form of an emulsion. The first step of the process consists of exfoliating NTs in an aqueous surfactant solution. This step can be monitored by UV-Vis spectroscopy. Four experimental techniques have been developed in order to determine the minimum amount of surfactant, which is necessary to reach the highest degree of exfoliation of the NTs. The key step of this latex-based process is mixing a stable dispersion of NTs, covered by surfactant molecules, with a polymer latex. The use of this technology results in conductive nanocomposites with a low percolation threshold. Several procedures were explored in order to improve the properties of the materials, like tuning the characteristics of the polymer matrix.
