A practical and environmentally-friendly method, i.e. the high temperature-mechanical mixing by using an internal mixing device and a two-roll open milling device is used to produce the carbon blacks-free electrically conductive sulfur-vulcanised rubber blends of solid poly(butadiene-co-acrylonitrile) and solid sulfonic acid doped polyaniline. The addition of sulfur vulcanisation system does not affect the electrical properties of the vulcanised blends. All vulcanised blends prepared by using this method show useful electrical conductivities up to the order of 10−2 S/cm, good tensile strengths up to 18.0 MPa and colourable with the addition of a whitening agent. As a result, they have good potential to be used for manufacturing any antistatic products, electrostatic discharge or dissipative products and electromagnetic or radio frequency interferences shielding products.
