Abstract: The various embodiments of the present invention disclose an peroxide-vulcanised TPVs based on Hevea Brasiliensis natural rubber, polypropylene and solid sulfonic acid doped polyaniline [PAni.DBSA] with useful electrical conductivities (up to about 2.1±0.2 S/cm] can be produced by using an internal mixer. The peroxide-vulcanised TPVs exhibit useful physical properties and also possess a reasonable good electromagnetic interferences shielding effectiveness. These peroxide-vulcanised TPVs could be recycled up to 4 times without significant loss of their EMI SE, electrical and physical properties. As a result, they have good potential to be used for manufacturing any EMI shielding products, such as EMI shielding seals and gaskets.

Abstract: 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 vulcanization 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 colorable 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.
