Blends of poly(butadiene-co-acrylonitrile) NBR and polyaniline dodecylbenzenesulphonate PAni.DBSA with electrical conductivities up to 10“1 S.cm“1 have been successfully prepared using the technique of solution mixing and casting. Compatibility of both NBR and PAni.DBSA was found to be maximised by the introduction of hydroquinone as a compatibiliser. Blends prepared with added hydroquinone exhibited the lowest electrical conductivity percolation threshold and were more conductive than the ones without any compatibiliser. Transmission electron micrographs of blends with added compatibiliser showed the lowest level of phase separation. FT-IR spectra and DSC thermal of blends with added compatibiliser also showed the largest peak and temperature shifts respectively. These phenomenons occured due to the higher intermolecular interactions between the two blended polymers in the presence of hydroquinone.

Abstract

Blends of poly(butadiene-co-acrylonitrile) NBR and polyaniline dodecylbenzenesulphonate PAni.DBSA with electrical conductivities up to 10“1 S.cm“1 have been successfully prepared using the technique of solution mixing and casting. Compatibility of both NBR and PAni.DBSA was found to be maximised by the introduction of hydroquinone as a compatibiliser. Blends prepared with added hydroquinone exhibited the lowest electrical conductivity percolation threshold and were more conductive than the ones without any compatibiliser. Transmission electron micrographs of blends with added compatibiliser showed the lowest level of phase separation. FT-IR spectra and DSC thermal of blends with added compatibiliser also showed the largest peak and temperature shifts respectively. These phenomenons occured due to the higher intermolecular interactions between the two blended polymers in the presence of hydroquinone.
