Conducting polymer composites of polythiophene with natural and synthetic rubbers

Electrochemical synthesis of conducting polymer composites of polythiophene was achieved. Synthetic and natural rubbers were used as the insulating polymer matrices, FT-IR, differential scanning calorimetry (DSC) , scanning electron microscopy (SEM) and mass spectrometry (MS) were utilized to characterize the composite blends. The conductivity measurements were done by using a standard four-probe technique. The above-mentioned methods show that the resultant composites have different properties compared to polythiophene due to interaction of the rubbers with electrochemical polymerization of thiophene, whereas the same argument is not valid for the polypyrrole synthesis via the same procedure.

Thermal degradation of polythiophene-natural rubber and polythiophene-synthetic rubber conducting polymer composites
Hacaloğlu, Jale; Akbulut, Ural; Toppare, Levent Kamil (1997-01-01)
Thermal degradation of conducting polymer composites of polythiophene and rubbers was studied by direct and indirect pyrolysis mass spectrometry techniques. The samples were prepared by electrooxidation of polythiophene using natural rubber or synthetic rubber as the insulating matrix. Presence of decomposition products which were not observed during pyrolysis of pure polythiophene and rubbers, and disappearance of rubber-based pyrolysis mass peaks, together with changes in thermal stability and behaviour, ...
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...
Conducting polymer composites of polypyrrole and polyimide
Selampinar, F; Akbulut, Ural; Toppare, Levent Kamil (1997-01-01)
A conducting composite of polypyrrole with a polyimide as the insulating matrix polymer was prepared via electrochemical methods. The characterization of the composite was done by FTIR, SEM and TGA studies. Conductivity and solubility studies together with spectroscopic methods reveal that a chemical interaction between the two polymers exists.
Thermal characterization of composites of polyamide-6 and polypropylene involving boron compounds via direct pyrolysis mass spectrometry
İşbaşar Afacan, Güllü Ceyda; Hacaloğlu, Jale; Yılmazer, Ülkü; Department of Polymer Science and Technology (2013)
In this work, the effects of addition of boron compounds, boron phosphate (BPO4), zinc borate (ZnB), borosilicate (BSi) and lanthanum borate (LaB), on thermal degradation characteristics of composites of polyamide 6 (PA6) and polypropylene (PP) are analyzed via Direct Pyrolysis Mass Spectrometry (DP-MS) technique. The composites of PA6 involve nitrogen containing flame retardants, melamine (Me) or melamine cyanurate (MC); or phosphorus containing flame retardant, aluminum diethylphosphinate (AlPi), with or ...
Thermal analysis of a new thiophene derivative and its copolymer
Aslan, E.; Toppare, Levent Kamil; Hacaloğlu, Jale (2008-06-01)
Thermal characteristics of a new thiophene derivative, 2-(thiophen-3-yl-)ethyl octanoate (OTE), its homopolymer (POTE), and copolymer with thiophene P(OTE-co-Th) were investigated via pyrolysis mass spectrometry. Thermal degradation of the copolymer started by lose of side chains and thiophene involving products evolved almost in the same temperature range where PTh degradation was detected, at slightly higher temperatures than PTh backbone decomposed during the pyrolysis of POTE. The extent of doping and n...
