Abstract

The paper describes investigation on the network polymer electrolytes based on polyethylene glycol diacrylates\ud and polyester diacrylates PEDA with introduction the nanopowders TiO2, Li2TiO3 and SiO2, with\ud different size and shape. Much attention is paid to effects of nanoparticles additives on the ionic conductivity\ud of network polymer electrolytes. The work is aimed to explanation of the mechanism of additives action\ud on Li+ - ion transport and structural changes of the polymer chains and the solvent molecules. For these\ud purposes the NMR method with rotation under a magic corner on nuclei 1H and NMR method with a pulsed\ud magnetic field gradient at the nuclei 7Li were used.
