Polypyrrole and its copolymers with terepthalic acid bis-(2-thiophen-3-yl-ethyl)ester, (P(TATE-co-Py) were characterized by direct pyrolysis mass spectrometry to investigate the effects of dopant on thermal stability and conductivity. Conductivities of the films were measured with four-probe technique, and the results were compared with the pyrolysis data. In general, an increase in conductivity was detected as the stability of dopant increased. The extent of doping and the strength of interaction between the dopant and the polymer were decreased upon copolymerization with terepthalic acid bis-(2-thiophen-3-yl-ethyl)ester.

Investigation of copolymers of thiophene-functionalized polystyrene with pyrrole by pyrolysis mass spectrometry Papila, Ozge; Toppare, Levent Kamil; Hacaloğlu, Jale (2006-06-01) The thermal and structural characterization of electrochemically synthesized thiophene-functionalized polystyrene and pyrrole (PS/PPy) and their copolymers were investigated by direct pyrolysis mass spectrometry. The pyrolysis data confirmed the growth of polypyrrole onto the pendant thiophene moiety of polystyrene. It is determined that the electrolytic film has different properties from the mechanical mixture and the related homopolymers.
Direct pyrolysis mass spectrometry studies on thermal degradation characteristics of poly(phenylene vinylene) with well-defined PSt side chains Nur, Y.; Çolak, Demet; Cianga, I.; Yagci, Y.; Hacaloğlu, Jale (2008-10-01) Thermal degradation characteristics of a new macromonomer polystyrene with central 4,4'-dicarbaldehyde terphenyl moieties and poly(phenylene vinylene) with well-defined polystyrene (PPV/PSt) as lateral substituents were investigated via direct pyrolysis mass spectrometry. A slight increase in thermal stability of PSt was detected for (PPV/PSt) and attributed to higher thermal stability of PPV backbone. It was almost impossible to differentiate products due to the decomposition of PPV backbone from those pro...
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-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.
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...
