Resumo: | Two imidazolium-based ionic liquids (C4MIMTf2N and C4MIMBF4) were used to verify their influence on polyaniline (PANI) and nitrile rubber (NBR)/PANI blend properties and the vulcanization process. High conductivity values were observed for PANI-C4MIMTf2N samples and no interference was found for the C4MIMBF4 samples. These materials were added to NBR by mechanical mixing. Based on the torque results, the presence of C4MIMBF4 does not protect the vulcanization reaction of NBR with PANI as performed by C4MIMTf2N. The highest conductivity value was obtained with 7 wt. % of PANI-DSBA-C4MIMTf2N (10-6 S/cm). This result is attributed to the more effective interaction of PANI and NBR phases promoted by the ionic liquid. |
