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 to degradation of rubbers during electrooxidative polymerization. The multiscan cyclic voltammetry runs showed that polythiophene is also electroactive on the rubber coated metal electrodes, with a sma!l shift in the redox peaks compared to the one on the bare electrode.

A conducting composite of polythiophene: Synthesis and characterization Vatansever, Fatma; Hacaloğlu, Jale; Akbulut, Ural; Toppare, Levent Kamil (1996-01-01) Conducting polymer composites of polythiophene, using a polyamide as the insulating matrix, were prepared via electrochemical methods. The characterization of the composite was done by scanning electron microscopy, differential scanning calorimetry, thermogravimetric analysis, Fourier transform infrared and pyrolysis studies. The conductivities were measured by a four-probe technique. The cited methods revealed that the composites have properties different from those of simple mechanical mixtures of the two...
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.
The characterization of polyaniline and polypyrrole composites by pyrolysis mass spectrometry Hacaloğlu, Jale; Kücukyavuz, Zühal (2009-09-05) 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...
A pyrolysis mass spectrometry study of polythiophene copolymers Aslan, Evren; Hacaloğlu, Jale; Toppare, Levent Kamil (2007-05-01) The thermal behaviour of copolymers of thiophene with decanedioic acid bis-(2-thiophen-3-yl-ethyl)ester (DATE) and terephthalic acid his(2-thiophen-3-yl-ethyl)ester (TATE) prepared by potentiostatic polymerization was studied via pyrolysis mass spectrometry. It was determined that the electrolytic films correspond to the related homopolymers. The increase in thermal stability of ester linkages, and evolution of characteristic degradation products of TATE and DATE together with thiophene based products above...
Characterization of polypyrrole/polytetrahydrofuran graft copolymers by direct pyrolysis mass spectrometry Özdilek, Ceren; Toppare, Levent Kamil; Yagci, Yusuf; Hacaloğlu, Jale (2002-01-01) The thermal decomposition pathways and products of pyrrole ended-polytetrahydrofuran (PTHF), p-toluene sulfonate doped polypyrrole (PTS-PPY) and polypyrrole/polytetrahydrofuran (PTS-PPY/PTHF) graft copolymers have been investigated by direct pyrolysis mass spectrometry (DPMS). The data suggest that PTHF degrade via mixed random cleavage and unzipping mechanism followed by hydrogen transfer reactions. Decomposition of dopant in the high temperature range is attributed to a strong interaction between the dopa...
