Effect of POSS-PEG on Morphology and Ionic Conductivity in Nanocomposite Polymer Electrolytes |
| 초록 |
All soild-state lithium batteries will contribute to the flexible and wearable electronics and solid polymer electrolytes (SPEs) are promising candidates for replacing liquid electrolytes. Nanocomposites based on hybrid nanoparticles which are expected to exhibit both the advantages of organic and inorganic improve their properties. Hybrid nanoparticles (1 ~ 2 nm) are compatible more than inorganic filler because of their functionalized with poly(ethylene glycol) (PEG) moieties. The hybrid nanoparticles enhanced the polymer chain segmental mobility and relaxation time (τs) of nanocomposites by 1.5 times. Also the glass transition temperature of nanocomposites decreased from -30.2 to -45.3 oC and ionic conductivity increased with nanoparticle loading. Dynamics and morphology of nanocomposites depended on loading of nanoparticles. |
