There have been extensive studies on structural characterization of conducting polypyrrole, PPY using various techniques. The two proposed structures are the aromatic form corresponding to the undoped state and the quinoid form corresponding to the doped state. However, actual structure appears to be more complicated and the relationship between the dopant used and the structure was not totally clarified. In this study direct insertion probe pyrolysis mass spectrometry technique was applied to monitor thermal decomposition products of polypyrrole which may further be used for structural elucidation. Three different dopants namely, p-toluene sulfonate, tetrafluoroborate and dodecyl sulfate were used in the synthesis of polypyrrole to investigate the effect of dopant on thermal stability and structure.

Thermal characterization of phenol and bisphenol-A based polybenzoxazines Bagherifam, Shahla; Hacaloğlu, Jale; Department of Polymer Science and Technology (2009) Although, several researches on synthesis and characterization of benzoxazines and polybenzoxazines have appeared in the literature, detailed studies on thermal characterization are still limited. In this study, polymerization and thermal degradation mechanisms of benzoxazines were investigated via direct pyrolysis mass spectrometry. Benzoxazine monomers prepared by reactions of phenol or bisphenol- A with aniline or methyl amine were analyzed to investigate the effects of the structures of phenyl and amine...
Nanocomposites based on recycled poly(ethylene terepthalate) Tolga, Aslı; Yılmazer, Ülkü; Department of Chemical Engineering (2005) In this study, the effects of glycol type, organoclay type and concentration on the final properties of nanocomposites based on recycled poly(ethylene terephthalate) was investigated. For this purpose, first recycled PET was glycolysed and after that unsaturated polyester-montmorillonite nanocomposites were synthesized by using three different types of glycols (i.e. ethylene glycol (EG), propylene glycol (PG) and diethylene glycol (DEG)). As the first step, all the compositions were prepared by Cloisite 30B...
Characterization of BF4- doped polythiophene via pyrolysis mass spectrometry Gozet, T.; Önal, Ahmet Muhtar; Hacaloğlu, Jale (2003-04-04) In this work, electrochemically polymerizated polythiophene have been characterized by direct pyrolysis MS and Curie point pyrolysis GCMS techniques. The effect of doping level and type of the dopant on thermal characteristics and decomposition products of polythiophene have been investigated. It has been determined that the thermal degradation of polythiophene occurs in two steps, the first being the loss of the dopant, and the second being the degradation of the polymer main chain. The temperature range a...
The effect of long-term ambient aging on the mechanical properties of conducting polysiloxane-polypyrrole graft copolymers Biran, C; Toppare, Levent Kamil; Tincer, T; Yagci, Y; Harabagiu, V (2003-05-01) The mechanical behavior of conducting polysiloxane-polypyrrole graft copolymers has been investigated as a function of ambient oxidative aging period. Graft copolymers of N-pyrrolyl-terminated polydimethylsiloxane (SPPy) with pyrrole were synthesized electrochemically at constant potential by using p -toluene sulfonic acid as the supporting electrolyte. Mechanical tests were performed on both unwashed and dichloromethane -washed copolymers after aging. An initial decrease followed by an increase in the tens...
Pyrolysis mass spectrometric analysis of copolymer of polyacrylonitrile and polythiophene Oğuz, Gülcan; Hacaloğlu, Jale; Department of Polymer Science and Technology (2004) In the first part of this work, the structural and thermal characteristics of polyacrylonitrile, polyacrylonitrile films treated under the electrolysis conditions in the absence of thiophene, polythiophene and the mechanical mixture and a conducting copolymer of polyacrylonitrile/polythiophene have been studied by pyrolysis mass spectrometry technique. The thermal degradation of polyacrylonitrile occurs in three steps; evolution of HCN, monomer, low molecular weight oligomers due to random chain cleavages a...
