Abstract

Electrically conductive composites consisting of carbon nanotubes (CNTs) in a poly(2,6-dimethyl-1,4-phenylene ether)/polystyrene (PPE/PS) blend are prepared by latex technology. The latter consists of 4 steps: preparation of an aqueous dispersion of CNTs, mixing with a polymer latex, solvent removal by freeze–drying and processing. In the first route, PPE/PS blend latexes are directly used to prepare nanocomposites by latex technology. The CNT/PPE/PS composites display an increased glass transition temperature compared to unfilled material and a percolation threshold as low as 0.3 wt% of CNTs. Secondly, CNT/PS masterbatches prepared by latex technology are mixed with PS/PPE blend pellets by extrusion. This approach constitutes a potential first step towards an industrially viable process. mame201300105-gra-0001
