摘要
高分子參雜鹼金屬鹽類形成高分子電解質,它們應用於高分子鋰電池中。一般推測,高分子電解質的離子導電是經由兩種方式。第一個關聯的是經由電荷在高分子主體的協調位置上移動,另一方面離子導電的導電性隨著高分子的彈性而增加。高分子的雷利-布里淵頻譜可以了解在10^8到10^11赫茲的機械鬆弛現象。我們利用布里淵散射來探測聚乙二醇/氯化鋰的彈力性質;高分子鍊在改變溫度下的彈性變化、自由離子的比例還有它們和高分子的交互作用都會影響布里淵頻譜。這些實驗證明了這個技術的可行性還有它在探測高分子電解質中的各種交互作用是一種好方式。


Abstract
Abstract
The polymer electrolytes (ion conducting polymers) consist of macromolecules (usually in the form of polyethereal units) that are doped with alkali mental salts. The polymer electrolytes are being used in Li-polymer buttery. It is suggested that conductivity in these systems takes place through two distinct events. The first is associated with the charge migration of ions between coordination sites in the host material, and the second is that the conductivity is generally observed to rise with increasing flexibility of the polymer chains. Rayleigh-Brillouin scattering spectra of molecular liquids will provide mechanical relaxation information in the frequency range from 10^8 to 10^11 Hz. We have carried out the Brillouin scattering study of PEG400/LiCl mixtures to probe its elastic properties. The change in the flexibility of polymer chains at different temperatures, the fraction of free ion, and their interactions with polymer all effect the Brillouin spectrum and the present work suggests the usefulness of this technique as an useful tool to probe the various interactions in polymer electrolytes.
