Morphological Study of Sulfonated Styrenic Pentablock Copolymer/Graphene Oxide/Ionic Liquid Membranes |
| 초록 |
Herein, we report sulfonated styrenic pentablock (SSPB) copolymer/graphene oxide (GO)/ionic liquid (IL) membranes as polyelectrolytes of polymer actuators. We sucessfully fabricated the SSPB/GO/IL membranes through conventional solution casting methods. The IL used was 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide. It was observed via small-angle X-ray scattering that the membranes had a well-defined microseparated morphology, consisting of ionic domains and non-ionic domains, on the scale of several tens of nanometers. The morphology led to a high ion conductivity as well as an excellent mechanical properties. Finally, the SSPB/GO/IL membranes were engaged as the polyelectrolyte layer of a polymer actuator and the actuation behavior was investigated. |
