At the same time level of their ionic conductivity is more higher than that of poly(tetramethylene glycol) based polyurethanes. The polymer electrolytes based on PEO-PPO-PEO triblock copolymer and lithium perchlorate is more homogenaeous than polymer electrolytes based on the initial polyethers and LiClO4 and characterized by higher values of ionic conductivities (up to 10-4 S/cm.). Linear polyionenes show a high level of ionic conductivity (up to 10-5 S/cm) and are completely amorphous at room temperature. It was concluded that the systems considered are perspective materials for different polymer electrolyte applications.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
