| Abstract: |
Layers of ethylene carbonate (EC) modified CuI /PVA polymer composite have been prepared by growth of CuI nano particles in an aqueous solution of PVA followed by casting at room temperature. The structural, thermal, optical, electrical and di-electrical characterization of polymer composites was investigated using different techniques. These investigations confirm the growth of CuI nano particles and reduction of PVA crystallinity by increasing ethylene carbonate concentration. The FT-IR absorption shows broadening of absorption bands which attributed to polymer composite plasticization while there is a decrease in the optical energy gap recoded from the optical absorption and an increase of bulk conductivity with reduction in activation energy. The variation of the dielectric permittivity and dielectric loss with EC content are found to obey Debye dispersion relations. Key words: CuI/PVA polymer composite, electrical characterization, optical band gap, bulk conductivity *Corresponding author. Tel.:+201061653973 E-mail address: dr.shaimaa0206@hotmail.com |
