Abstract
To improve the damping properties of rubbers, organic tackifiers such as hydrocarbon resins, rosin esters, and polyterpenes are often incorporated to increase the intermolecular friction of the rubber, thus increasing the energy dissipation (damping) during dynamic loading. However, this is often at the expense of the cross-linking density and mechanical properties of the rubbers. Ionic cross-links introduce unique properties to rubbers, such as a combination of mechanical reinforcement and high extensibility, as well as self-healing and damping, thanks to the reversible ionic association. Hence creating an ionic network would be an interesting alternative to adding small molecular tackifiers to rubbers. The reversible ionic association inevitably causes structural instability over time (i.e., creep) or at elevated temperatures (ionic transition generally happens at 60–80 °C). To balance the dynamic damping, viscoelasticity, and mechanical stability of these materials, we prepared 1-vinyl imidazole modified brominated poly(isobutylene-co-isoprene) (BIIR) elastomers by solid-state rubber compounding and curing processes, and we investigated the effects of ionic networks and an aliphatic petroleum resin (C5) on the viscoelastic and electromechanical properties of the ionic-cross-linked elastomers. We found that the mechanical reinforcement can be achieved simultaneously with a broad effective damping temperature range through optimizing the ionic network and C5 concentrations. The polar ionic clusters also increased the dielectric permittivity while maintaining a low dielectric loss of the elastomers. The ionic modified BIIR exhibited actuation and energy harvesting properties similar to those of the commercial VHB-4910 elastomer under similar configurations, which provides alternative dielectric elastomers with reprocessability for vibration and energy harvesting applications.
