Sažetak
Nanocomposite polymer electrolytes based on poly(ethylene oxide)/Cloisite 25A were prepared by melt intercalation method. Samples were made with different weight ratios of poly(ethylene oxide) (PEO) to Cloisite 25A (25A) while the ratio of cation of lithium bis(oxalato)borate (LiBOB) to ether-oxygen was kept constant at EO : Li = 8. By comparing the obtained PEO/25A/LiBOB samples the effect of Cloisite 25A nanofiller and LiBOB salt on the structure and thermal properties was determined. FTIR analysis revealed the interaction between polymer and salt. The addition of Cloisite 25A additionally affected the crystal structure of PEO in PEO/25A/LiBOB samples. The thermal transitions and degree of crystallinity of PEO in PEO/25A/LiBOB samples were investigated using differential scanning calorimetry (DSC). It was found that the crystal structure of PEO completely disappeared on the addition of both Cloisite 25A and LiBOB. This was accompanied by an increase in the glass transition temperatures which is related to the stiffening effect of lithium salt on PEO chains. Thermogravimetric analysis (TGA) showed lower thermal stability and more complex thermal degradation process of nanocomposite polymer electrolytes compared to PEO.
