Structural, optical, thermal, and dielectric properties of polyethylene oxide/carboxymethyl cellulose blend filled with barium titanate

摘要: Abstract Nanocomposite films of polyethylene oxide/carboxymethyl cellulose (PEO/CMC)/barium titanate (BaTiO3) were prepared using the solution casting technique. The results X-ray diffraction (XRD) analysis depicted semicrystalline nature PEO/CMC, which was largely reduced due to BaTiO3 loading. Fourier transform infrared (FT-IR) spectroscopy showed interaction between components blend, PEO and CMC, through formation hydrogen bond confirmed functional groups in particular C-O-C for COO− CMC. From Ultraviolet/visible (UV/vis.) absorption spectra, sharp edge UV range filled samples red shifted optical energy gap also calculated. effect on glass transition, melting point, decomposition temperatures investigated differential scanning calorimetry (DSC) AC conductivity results, electrical properties improved depending temperatures, frequencies, content within polymeric matrix. This indicated presence charge carriers that transported defect sites by hopping. Furthermore, mechanism conduction its dielectric parameters had been studied. Transmission electron micrographs revealed cubic shape with an average size 15–50 nm. These observations indicate these nanocomposite are potential candidates various industrial applications, such as pyroelectric sensors electromechanical transducers, ceramic capacitors a material inserted two electrodes.
