Amphiphilic polymer gel electrolytes. II. Influence of the ethylene oxide side-chain length on the gel properties
(2001) In Journal of Polymer Science. Part B, Polymer Physics 39(13). p.1519-1524- Abstract
- Amphiphilic polymers consisting of copolymethacrylates carrying about 26 wt % ethylene oxide [(EO)(n)] side chains of different lengths were used as matrices in gel electrolytes. The gel electrolytes were composed of 30 wt % copolymer and 70 wt % 1 M LiPF6 in a mixture of ethylene carbonate and gamma -butyrolactone (2/1 w/w). The coordination of lithium ions by the (EO)(n) side chains in competition with the solvent was studied by Raman spectroscopy. A significantly stronger lithium coordination was observed when the gel electrolyte was based on a copolymer carrying (EO)(9) units in comparison with copolymers having (EO)(1), (EO)(2), and (EO)(4) units. Despite the observed stronger lithium coordination by (EO)(9) units in the gel, the ion... (More)
