Sažetak
Poly(ethylene oxide)/lithium montmorillonite (PEO/LiMMT) composites were prepared by mixing and ultrasonication PEO and LiMMT in water. Characterization of PEO/LiMMT composites was performed by differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FT-IR) and non-isothermal thermogravimetry (TGA). DSC and TGA reveal that higher loadings of LiMMT significantly influence the crystallinity, melting temperatures and thermal stability of PEO, respectively. Glass transition temperatures of PEO do not change with addition of LiMMT. FT-IR analysis shows that the helical structure of PEO chains is distorted in PEO/LiMMT composites. Changes of activation energy in composites compared to pure PEO indicate possible changes in the mechanism of the non-isothermal degradation of PEO due to addition of LiMMT.
