Poly(N-vinylimidazole) was synthesized by free radical polymerization. It was quaternized with methyl iodide. The samples were doped with iodine and borontrifluoride. Products were characterized by elemental analysis, Fourier transform infra-red spectroscopy and differential scanning calorimetry techniques. The maximum electrical conductivities achieved were 10(-4) S cm(-1) for BF3-doped and for I-2-doped QPVI. The decrease of electrical conductivity in open atmosphere with time was also studied to understand the stability of doped polymers. Temperature dependence of electrical conductivity exhibits a semiconductor behaviour. Copyright (C) 1996 Elsevier Science Ltd.


Synthesis, characterization and electrical properties of iodinated poly(N-vinylimidazole)
Ozyalcin, M; Kucukyavuz, Z (1997-03-31)
Poly (N-vinylimidazole) was synthesized by radical polymerization. The synthesis of this conducting polymer was achieved via iodination before doping. Characterization of the product was based on elemental analysis, FT-IR spectral analysis and differential scanning calorimetry (DSC) techniques. The long-lasting conductivity of iodinated poly (N-vinylimidazole) leads us to propose that a more stable charge transfer complex was formed between the dopant and polymer. The changes in conductivity of iodinated po...
Synthesis, characterizations and investigation of thermoluminescence properties of strontium pyrophosphate doped with metals
Ilkay, L. S.; ÖZBAYOĞLU, GÜLHAN; Yılmaz, Ayşen (2014-11-01)
Strontium pyrophosphate, Sr2P2O7, was synthesized by solid-state synthesis method; the product was co-doped with copper-silver (Cu-Ag), copper-indium (Cu-In) and manganese-praseodymium (Mn-Pr) oxides (CuO, MnO, In2O3, Pr6O11 and AgNO3) by solid-state reaction method. The variation of dopant concentrations was investigated from 0.5 to 15% by weight. In addition to these processes, chemical characterizations of samples and the investigation of thermoluminescence (TLD) properties of strontium pyrophosphate wit...

Ozyalcin, M; Kucukyavuz, Z; Jarvaherian, A; Kucukyavuz, S (1997-01-01)
Poly(4-Vinylpyridine) was synthesized by free radicalic polymerization. Solution doping process with metallic sodium was carried out. A conductivity value around 10(-6) S/cm was obtained. Relative change in the conductivity with dopant concentration, temperature dependence of conductivity, conductivity behavior in atmospheric conditions for the samples were analyzed. SEM and EDX techniques mere also used for the characterization of the polymer.
Electrically conductive polymer grafts prepared by electrochemical polymerization of pyrrole onto poly[(methyl methacrylate)-co-(2-(N-pyrrolyl) ethyl methacrylate)] electrodes
Balci, N; Akbulut, Ural; Toppare, Levent Kamil; Stanke, D; Hallensleben, ML (1998-01-01)
Pyrrole was grafted on poly[(methyl methacrylate)-co-(2-(N-pyrrolyl) ethyl methacrylate)] (PMMA-co-PEMA) using constant potential electrolyses. The thermal stability of PMMA-co-PEMA was improved as a result of electrochemical grafting with pyrrole. The electrochemical behavior of the films was studied by cyclic voltammetry. Pyrrole was found to be electroactive on PMMA-co-PEMA electrodes.
Electrorheological properties of kaolinite, polyindole, and polyindole/kaolinite composite suspensions
Arslan, Yasin; Unal, Halil Ibrahim; Yilmaz, Hasim; Sari, Bekir (Wiley, 2007-06-05)
In this study, polyindole (PIN) and polyindole/kaolinite (PIN/KAO) composite were synthesized by free radical polymerization using FeCl3 as an initiator. Average particle sizes (d(50)) of PIN and PIN/KAO composite were determined by dynamic light scattering (DLS) as 7.2 and 6.2 mu m, respectively. The samples were characterized by FTIR, elemental analysis, DSC/TGA and SEM measurements. Suspensions of KAO, PIN, and PIN/KAO composite were prepared in silicone oil (SO) and the sedimentation stabilities were de...
