    • Photosensitization of PVC dehydrochlorination by hydroquinone for improved optical and electrical properties 

      Balci, S.; Birer, O.; Süzer, Şefik (Elsevier, 2004)
      Hydroquinone (HQ) is incorporated into the PVC films containing methyl violet or polyaniline (emeraldine base) for sensitizing the UV induced optical or electrical changes, respectively. It is observed that introduction ...
    • UV-induced electrical and optical changes in PVC blends 

      Süzer, Şefik; Birer, O.; Sevil, A. U.; Guven, O. (Springer, 2001)
      2-Chloro-polyaniline (2-Cl-PANI) in its non-conducting (emeraldine base, EB) form, prepared by a chemical route, was dissolved together with poly-(vinylchloride) (PVC) in THF for casting into thin (10-50 μm) films. Upon ...
    • UV-Vis, IR, and XPS analysis of UV induced changes in PVC composites 

      Birer, O.; Süzer, Şefik; Sevil, U. A.; Guven, O. (Elsevier, 1999-05-25)
      PVC undergoes a high degree of dehydrochlorination when exposed to energetic photons. The released HCl (acid), however, can be trapped if a suitable trapping material (base) is also enclosed within the solid matrix as a ...
    • XPS investigation of thin SiOx and SiOxNy overlayers 

      Birer, O.; Sayan, S.; Süzer, Şefik; Aydınlı, Atilla (Elsevier, 1999-05-04)
      Angle-resolved XPS is used to determine the thickness and the uniformity of the chemical composition with respect to oxygen and nitrogen of the very thin silicon oxide and oxynitride overlayers grown on silicon. (C) 1999 ...
