Özet:

 

Pure poly (ethylene oxide) (PEO) films and PEO-FeCl3 films  of various concentration were prepared and studied for thermal and  optical properties.  Various analytical techniques like XRD, EDX, SEM,  TGA, and UV were used to examine the structural properties of PEO and  PEO-FeCl3 systems.  X-ray scans (XRD) revealed the existence of some  crystalline part in the PEO matrix.  The concentration of FeCl3 has a  great effect on the crystallinity of PEO. Thermogravimetric analysis  (TGA) data established that accumulation of FeCl3 to PEO films  enhanced the thermal stability of PEO. The optical properties of these  systems were also studied in the UV-Visible region as a function of  FeCl3 concentration at room temperature.  The obtained data were  analyzed in terms of absorption formula for non-crystalline materials.  From the measured absorption data optical energy gaps (Eopt) were  determined.  The optical energy gap was found to decrease with the  increase in FeCl3 concentration, which indicates that FeCl3  concentration had a significant influence on optical energy band gap.  The absorption coefficient increased sharply at concentration of  FeCl3 (5%) wt as compared with the pure PEO.
