New blend system of quaternized polysulfone/polyvinyl alcohol was investigated, as to its optical and electronic properties. Optical properties were analyzed by refractivity and transmission spectra. In order to obtain optical parameters, an approach proposed by Tauc for amorphous semiconductors was used, because of the similarity of the absorption edges. At the same time, the frequency-dependent-dielectric...
Nanocomposite thin films consist of conjugated polymer; MEH-PPV and inorganic material; ZnO were deposited using low cost spin coating method. The thin films characteristics were investigated in term of their electrical and optical properties; as each of it were heated at different temperature. The electrical properties of the thin films were studied to identify whether the nanocomposite thin films...
Relationship between the changing in structure and the electrical properties of modified poly(3-hexylthiophene) (P3HT) was examined. For modified P3HT two types of acceptor molecules including 1,4-Bis(5-brothien-2-yl)-2,3,5,6-tetrafluoro benzene (TFT) and 2,1,3-benzothiadiazole (Bz) were added into the main chain of P3HT. These modifications have the effect to molecular ordering of modified polymer...
