Electrical behavior of polymer grafted nanotubes/polymer nanocomposites using N-doped carbon nanotubes

The fabrication of nanocomposites using N-doped tubes as fillers and PS and PSBS as polymeric matrices is discussed. The electrical characteristics of these materials are studied, and the percolation thresholds of different types of composites are described. We found that PS-coated tubes result in more efficient dispersions but exhibit higher percolation thresholds, whereas pristine doped-tubes result in better electrical conducting nanocomposites.
