Description: -
Description: Solution mixing and casting technique were successfully used to prepare blends of poly(butadiene-co-acrylonitrile) elastomer [NBR] and polyaniline dodecylbenzenesulfonate [PAni.DBSA] for the first time. These blends showed electrical conductivities up to 10-2 S.cm-1 and much more conductive than previous mechanically mixed blends. Compatibility of NBR-PAni.DBSA could be maximised using NBR with high acrylonitrile (ACN) content, as predicted on the basis of solubility parameter calculations. Optical and electron micrographs of blends prepared from NBR with 48wt% ACN showed reasonably low levels of phase separation. The FT-IR spectra of all blends resembled a superposition of spectrum of each pure material, but with significant peak shifts due to changing intermolecular interactions between the polymers. Under DSC analysis, thermal events for blends prepared with NBR 48wt% ACN also showed the largest temperature shifts relative to those for the pure polymers, echoing the evidence for interaction between the two polymers. Keywords: conductive blend; polyaniline; nitrile rubber (NBR)
