Exceptional versatility of solvated block copolymer/ionomer networks as electroactive polymers

Communication: Molecular-level insights into asymmetric triblock copolymers: Network and phase development

“…11 ) Due to their highly elastic molecular network, ABA copolymer systems are ubiquitous in a wide range of contemporary technologies requiring, for example, highly stretchable wires for flexible electronics, 12 nanostructured membranes for fuel cells, 13 micromolded substrates for microfluidics, 14 high permittivity nanocomposites for sensors, 15 and energy-efficient dielectric elastomers for actuators and energy-harvesting media. [16][17][18] Here, we seek to follow the transition from diblock copolymers, a soft materials archetype responsible for elucidating the mechanism of molecular self assembly, to triblock copolymers, another soft materials archetype in which a) Authors to whom correspondence should be addressed.

Electroactive Thermoplastic Dielectric Elastomers as a New Generation Polymer Actuators

“…However, electroactive thermoplastic dielectric elastomer, sometimes referred to as electroactive nanostructured polymers (ENP), is a quite new terminology in the field of electroactive polymers (Chmidt et al, 2008;Jang et al, 2011;Kim et al 2010Kim et al , 2011Shankar et al, 2007aShankar et al, , 2007bShankar et al, , 2007cShankar et al, , 2008Vargantwar, 2011). Thus, this book www.intechopen.com will focus on demonstrating unique electric actuation properties of the thermoplastic dielectric elastomers.…”

“…In Table 2 and Figure 8, actuation behaviors of SEBS gels were compared with those of other dielectric polymers (Shankar et al, 2007a(Shankar et al, , 2007b(Shankar et al, , 2007c(Shankar et al, , 2008Vargantwar, 2011). Although the SEBS gel materials possess low-to-moderate energy densities, they exhibit exceptional electroactive behavior owing to a easy composition tunability.…”
