Preparation and characterisation of electrically conductive thermoplastic vulcanisate based on natural rubber and polypropylene blends with polyaniline

Thermoplastic vulcanisates [TPVs] based on natural rubber, polypropylene and dodecylbenzenesulfonic acid-doped polyaniline [PAni.DBSA] with useful electrical conductivities (up to about 1.2 S [cm.sup.-1]) were produced by using an internal mixer. A very low electrical percolation threshold (about 2....

Description
Summary:Thermoplastic vulcanisates [TPVs] based on natural rubber, polypropylene and dodecylbenzenesulfonic acid-doped polyaniline [PAni.DBSA] with useful electrical conductivities (up to about 1.2 S [cm.sup.-1]) were produced by using an internal mixer. A very low electrical percolation threshold (about 2.0 wt.%/1.13 volume % of PAni.DBSA) was achieved for TPVs prepared via this method. All the TPVs exhibited useful physical properties and also a reasonable good electromagnetic interference shielding effectiveness [EMI SE]. The TPVs could be recycled up to 4 times without significant loss of their EMI SE, electrical and physical properties.
