چکیده    Polymer poly vinyl pyrrolidone (pvp) was doped with potassium hexafluoro phosphate (kpf6) and tio2 nanomaterials for different weight ratio (0, 10, 20) % were prepared by cast solution method to produced thin films of pvp/kpf6, pvp/tio2 and pvp/kpf6-tio2. the characterization of thin films such as tga analysis and the absorption spectra of thin films at the range wave number (300-800) nm were studied. it is found that the weight loss for polymer pvp was decreased with increase of weight ratio for added kpf6 but it has no effect with increase tio2 nanocomposite. for absorption spectra we see that adding tio2 nanocomposite to the polymer pvp is better than of kpf6 salt. and the energy gap for thin films decreases with increases nanocomposite and salt, the best result was for adding mixing of kpf6 salt with tio2 nanocomposite to polymer pvp which was equal to 1.1ev for the weight ratio 20% of pvp/kpf6-tio2 thin films.
