Ionic-filler Dispersed Polyelectrolyte Nanocomposite with the Increased Ion-Exchange Capacity for Electro-Active Transducer |
| 초록 |
Polyelectrolyte is recently highlighted as indispensable materials for electrochemical device. However, the commercial Nafion has the limited properties with the constant equivalent weight (EW). In this study, we synthesized ionic-functionalized nanofiller with the controllable EW. This has chemical structure of silica grafted with oligomeric acid by surface-modified condensation and subsequent polymerization of polystyrene sulfonic acid or acrylic acid. And then, Nafion dispersed with the synthesized filler was prepared by solution casting method. We demonstrate that the improved properties of the prepared polyelectrolyte enhance the feasibility of application to electrochemical devices. |
