摘要: In the present work, indigenous coal ash taken from Sharigh, Balochistan, Pakistan was used to prepare polymer electrolyte films with PEO/PMMA/LiClO4. Coal first characterized by various techniques like Surface and Porosity Analysis, SEM/energy dispersive X-ray analysis (EDX), transmission electron microscopy, Fourier transform infrared (FTIR), XRD. Chemical composition of confirmed EDX. Then, utility towards fabricating PEO/PMMA/LiClO4/coal composites studied in order explore its use as an additive for polymeric blend composites. The incorporation into diffraction UV/Visible spectroscopy, while ionic conductivity measurements were undertaken Impedance spectroscopy. Room temperature found increase sharply content reached maximum at 3.3 wt.% ash. Both direct indirect band gap energies decreased incorporation. decrease peak has improve performance blends.
