hi this work, direct insertion probe pyrolysis mass spectrometry technique was applied to investigate the thermal and structural characteristics of electrochemically prepared polyaniline (PANI), polypyrrole (PPy), and their composites/copolymers synthesized either by electrochemical polymerization of pyrrole on PANI-coated electrode (PANI/PPy) or by coating PANI on PPy (PPy/PANI) in H(2)SO(4) solutions. It has been determined that the polymer first coated on the electrode degraded to a certain extent during the polymerization of the second. The extent of degradation was greater for PPy and increased with the increase in acid concentration. On the other hand, the detection of mixed dimers confirmed copolymer formation.

A pyrolysis mass spectrometry study of polythiophene-polyamide composites Vatansever, F.; Akbulut, Ural; Toppare, Levent Kamil; Hacaloğlu, Jale (1996-01-01) The thermal behavior of composites of polythiophene and polyamide prepared by mechanical blending and electrochemical synthesis of polythiophene onto an electrode coated with polyamide have been studied thoroughly by the pyrolysis approach under both direct and indirect pyrolysis mass spectrometric analysis conditions. It is determined that the electrolytic film has different properties from the mechanical mixture and the related homopolymers.
Characterization of polyaniline via pyrolysis mass spectrometry Hacaloğlu, Jale; Kücükyavuz, Zühal (2008-04-05) In this work, direct insertion probe pyrolysis mass spectrometry technique was applied to investigate the thermal and the structural characteristics of electrochemically prepared HCl and HNO3-doped polyaniline (PANI) films. It has been determined that the thermal degradation of both samples showed three main thermal degradation stages. The first stage around 50-60 degrees C was associated with evolution of solvent and low-molecular-weight species adsorbed on the polymer, the second stage just above 150 degr...
Characterization of electrochemically synthesized p-toluene sulfonic acid doped polypyrrole by direct insertion probe pyrolysis mass spectrometry Uyar, Tamer; Toppare, Levent Kamil; Hacaloğlu, Jale (2002-01-01) A direct insertion probe pyrolysis mass spectrometry technique was used to perform a systematic thermal characterization of conducting polypyrrole doped with p-toluene sulfonic acid. The effect of dopant concentration on thermal stability and degradation products was investigated using undoped and dedoped polypyrrole samples. The data indicate that polymerization of pyrrole in the absence of dopant produces an aromatic structure, which transforms into the quinoid form at high dopant concentrations. Reductio...
A pyrolysis mass spectrometry study of polythiophene - Natural rubber and polythiophene - Synthetic rubber conducting polymer composites Yigit, S.; Hacaloğlu, Jale; Akbulut, Ural; Toppare, Levent Kamil (1997-01-01) The thermal behaviors and degradation products of conducting polymer composites prepared by electrooxidation of thiophene using natural rubber or synthetic rubber as the insulating matrix were studied by direct and indirect mass spectrometry techniques. The pyrolysis mass data revealed that a chemical interaction formed between the components of the composites during polymerization. Thermal characteristics of rubbers totally disappeared in the composites indicating presence of some chain scissions leading t...
The effect of triethanolamine on thermal decomposition of GAP Fazhoğlu, Hatice; Hacaloğlu, Jale (2002-01-01) The effect of triethanolamine (TEA) on thermal behavior of glycidyl azide polymer (GAP) has been investigated by direct pyrolysis mass spectrometry technique. It has been observed that thermal degradation of GAP-TEA mixture also begins with the cleavage of the side groups as in the case of GAP. Again, the main decomposition started with the elimination of molecular nitrogen from the azide functional group, and a quite similar degradation mechanism has been proposed. The increase in the thermal stability of ...
