Electrically conductive thermoplastic elastomer vulcanisate based on NBR and PP blends with polyaniline: Preparation and characterisation

Electrically conductive thermoplastic elastomer vulcanisates (tpvs) based on poly (butadiene-co-acrylonitrile) (nbr),polypropylene (pp) and dodecylbenzenesulphonic acid doped polyaniline (pani.dbsa) were produced by using an internal mixer. a very low electrical percolation threshold (about 1.5 wt %/0.85 volume % of pani.dbsa) was successfully achieved for tpvs prepared via this technique. all these tpvs showed useful physical properties and also a reasonable good electromagnetic interferences shielding effectiveness (emi se). these tpvs could be reprocessed up to four cycles without significant loss of their emi se,electrical and physical properties. as a result,this kind of tpv material has a very good potential of industrial application.
