Synthesis and characterization of poly (o-toluidine) POT blend with polyethylene oxide PEO as conducting polymer alloys

摘要

Conducting polymer alloys films poly (o-toluidine) (POT) blend with polyethylene oxide (PEO) have been prepared in chemical method. These films of POT/PEO blend prepared by mixed different ratio (0 – 10%, 30%, 50%, 70% , 90%) of POT with PEO. Thin films of these blends polymer were prepared by casting and spin coating . The optical properties where study for each ratio of blend. The optical analysis indicated that the transition was direct transition with energy gap degrees as POT increase from (3 eV to 1.4 eV). The electrical conductivity was measured by two probe method. The electrical conductivity increase from ( 1.85 x 10 -8 to 1.06 x 10-5) as POT increases. All result were discussed and measured by I-V characterized.
