Abstract: Bromine,as a dopant was adsorbed onto MWNTs to enhance the electrical conductivity of MWNTs. MWNTs were also modified by polystyrene. TEM and FESEM indicate that the modification of polystyrene improved the dispersion of Br-MWNTs in polymer matrix while the electrical conductivity of Br-MWNTs did not decrease.

Key words: electrical conductivity, polystyrene, dispersion, MWNTs, electrical conductivity, polystyrene, dispersion
