Conducting polymers of polysiloxane-polypyrrole were Synthesized by electropolymerization of the pyrrole monomer through pyrrole moieties in N-pyrrole-terminated polysiloxanes. Sodium paratoluene sulfonate was used as the electrolyte. Scanning electron microscopy (SEM) was used to determine the surface morphology of the films. The room-temperature conductivity values of the films were found to be in the range of 1.9-4.4 x 10(-4) (Omega cm)(-1), depending on the supporting electrolyte concentration. The temperature dependence of the dc conductivities of the copolymers having different dopant concentrations was investigated within the temperature range of 100-320 K. The evaluated para-meters showed that the electrical transport is dominated by variable range hopping. (C) 2002 Wiley Periodicals, Inc.

Synthesis and Characterization of a New Conducting Polymer Based on 4-(2,5-di-2-thiophen-2-yl-pyrrol-1-yl)-phthalonitrile
Yavuz, Arzu; Bezgin, Buket; Önal, Ahmet Muhtar (Wiley, 2009-12-05)
A new conducting polymer was synthesized by electrochemical polymerization of 4-(2,5-di-2-thiophen-2-yl-pyrrol-1-yl)-2-phthalonitrile (SNS-PN). Electrochemical polymerization of SNS-PN was performed in acetonitrile/0.2M LiClO4 solvent/electrolyte couple. Characterizations of the resulting polymer P(SNS-PN) were carried out by cyclic voltammetry, UV-vis, and Fourier transform infrared (FTIR) spectroscopic techniques. Spectroelectrochemical studies revealed that P(SNS-PN) has an electronic band gap of 2.45 eV...

New pi-conjugated polymers containing dithieno(3,2-b: 2',3'-d) pyrrole (DTP) were successfully synthesized via electropolymerization. The effect of structural differences on the electrochemical and optoelectronic properties of the 4-[4H-dithieno(3,2-b: 2',3'-d) pyrrol-4-yl] aniline (DTP-aryl-NH2), 10-[4H-dithiyeno(3,2-b: 2',3'-d) pirol-4-il] dekan-1-amine (DTP-alkyl-NH2), and 1,10-bis[4H-dithieno(3,2-b:2',3'-d) pyrrol-4-yl] decane (DTP-alkyl-DTP) were investigated. The corresponding polymers were characteri...
Conducting Polymer Composites of Multiwalled Carbon Nanotube Filled Doped Polyaniline
Yilmaz, Faris; Kucukyavuz, Zuhal (Wiley, 2009-01-15)
A multiwalled carbon nanotube (c-MWNT)/polyaniline (PANI) composite was synthesized by an in situ chemical oxidative polymerization process. With the carbon nanotube loading increased from 0 to 30 wt %,, the conductivity also increased and became weakly temperature-dependent. Fourier transform infrared spectroscopy studies showed that the synthesis by an in situ process led to effective site-selective interactions between the quinoid ring of the PANI and the multiwalled nanotubes, facilitating charge-transf...
Electrosynthesis of polyfuran in acetonitrile-boron trifluoride-ethyl ether mixture and its device application
Tirkeş, Süha; Önal, Ahmet Muhtar (Wiley, 2007-01-15)
Electrochemical polymerization of furan was achieved in acetonitrile/boron trifluoride/ethyl ether (CH3 CN/BF3/EE) mixture in the presence of tetrabutylammonium tetrafluoroborate via constant potential electrolysis at 1.4 V versus Ag/AgCl. Electrochemical behavior of furan was investigated in the same solvent mixture of varying ratios, utilizing cyclic voltammetry. Free-standing polyfuran (PFu) films were obtained in CH3CN/BF3/EE mixture (2/4/4; v/v/v) and characterized using FTIR spectroscopic technique. S...
Indium tin oxide nanoparticles as anode for light-emitting diodes
Çırpan, Ali (Wiley, 2006-02-15)
Thin films of indium tin oxide (ITO) nanoparticles have been investigated as anode materials for polymer light-emitting diodes. A luminance efficiency (0.13 cd/ A), higher than that (0.09 cd/A) obtained in a control devices fabricated on conventional commercial ITO anodes were found. The thin films were made by spin coating of a suspension followed by annealing. The ITO nartoparticle films have a stable sheet resistance of 200 ohm/sq, and an optical transmittance greater than 86% over the range of 400-1000 ...
