摘要: Abstract A new oligo-ether sulfate (SPEG) and linear polyether urethane (PU) have been synthesized successfully, a series of novel solid polymer electrolytes based on PU/oligo-ether complexes were prepared. Effects temperature, salt concentration (O:Na+, the molar ratio ether unit to sodium cation), content SPEG polydioxolane (PDXL) morphological structure ionic conductive property investigated in detail. It was found that had great effect samples. Results showed conductivity this system could reach 10−5 S cm−1 at medium temperature (60°C) dependence not an Arrhenius-type one. The increased with increase over whole range studied SPU-600 higher than SPU-400 same O:Na+. In addition, plasticizer PDXL its significantly influenced properties
