Polymer gel electrolyte with polyurethane-poly (hydroxymethyl EDOT) supramolecular network |
| 초록 |
Polymer gel electrolyte chemically bonded to a π-conjugated polymer was synthesized by graft copolymerization of MDI-terminated poly (hydroxymethyl EDOT) (MDI-PEDOT) and poly (ethylene glycol) (PEG) as a designed ladder-type structure. The successful formation of supramolecular network has been confirmed by analyzing Fourier transform infrared spectroscopy (FT-IR). A series of polyurethane (PU)-PEDOT and LiClO4 based polymer gel electrolytes were prepared with different concentration of O/Li+ ratios. The pH effect of optical change and electrical capacitance was investigated by UV–vis–NIR absorption spectroscopy and cyclic voltammetry. The ionic conductivities of PU-PEDOT/Li+ complexes at a fixed pH was also evaluated through impedance analysis based on a function of LiClO4 concentration. |
