In this study, Co, Cr or Au3+ functional polystyrene-block-poly(2-vinylpyridine), PS-b-P2VP complexes were prepared and characterized. Coordination of metal atom or ion to nitrogen atom of pyridine rings was confirmed by FTIR analyses. The strength and efficiency of coordination of P2VP blocks to Co, Cr or Au3+ mainly depends on charge and stability of the complex formed that is mainly related to the energy of d orbitals.The results reveal that the thermal stability of the polymer composite formed increases with the increase in strength of the coordination. Changes in thermal decomposition mechanism and product distribution were recorded. Degradation of P2VP units coordinated to Cr, Co or Au3+ was started by loss of pyridine units leaving an unsaturated and/or crosslinked polymer backbone that degraded at relatively high temperatures.

Characterization of polylactide/poly(ethylene glycol) blends via direct pyrolysis mass spectrometry Ozdemir, Esra; Tincer, Teoman; Hacaloğlu, Jale (2016-11-01) In this study, melt blended poly(lactic acid) and poly(ethylene glycol), (PLA)/PEG samples involving 10, 15 and 20 wt% PEG were prepared and characterized by direct pyrolysis mass spectrometry technique in addition to classical techniques such differential scanning calorimetry, thermogravimetric analyses and mechanical tests. The incorporation of PEG resulted in consistent and significant decrease in the tensile strength and modulus, and reduction in endothermic melting peak of PLA due to the plasticizing e...
Preparation and thermal characterization of poly(2-vinylpyridine) copolymers coordinated to Cr nanoparticles Öztürk, Yurdagül; Kayran, Ceyhan; Hacaloğlu, Jale (2015-06-01) In this study, polystyrene-block-poly(2-vinylpyridine), PS-b-P2VP, polyisoprene-block-poly(2-vinylpyridne), PI-b-P2VP and poly(methyl metacrylate)-block-poly(2-vinylpyridine), PMMA-b-P2VP, coordinated to Cr metal were synthesized and characterized by Fourier transform infrared, transmission electron microscopy and direct pyrolysis mass spectrometry techniques. Both thermal degradation mechanism and thermal stability of P2VP blocks were affected by the coordination of Cr nanoparticles to nitrogen of pyridine...
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...
Preparation and Characterization of Neodymia Doped PVA/Zr-Ce Oxide Nanocrystalline Composites via Electrospinning Technique Keskin, Selda; Uslu, Ibrahim; TUNÇ, TUNCAY; ÖZTÜRK, MUSTAFA; Aytimur, Arda (2011-01-01) In this study, neodymia doped poly(vinyl) alcohol/zirconium-cerium acetate (PVA/Zr-Ce) nanofibers were prepared using the electrospinning technique, and then calcined at 800 degrees C for 2 hours. For this purpose, PVA/Zr-Ce polymer solutions doped with different concentrations of neodymia were prepared using electrospinning technique, and then calcined and sintered at 800 degrees C for 2 hours. The effect of neodymia doping was investigated in terms of solution properties, morphological changes and thermal...
Preparation of Gadolina Stabilized Bismuth Oxide Doped with Boron via Electrospinning Technique TUNÇ, TUNCAY; Uslu, Ibrahim; Durmusoglu, Senol; Keskin, Selda; Aytimur, Arda; Akdemir, Ahmet (Springer Science and Business Media LLC, 2012-01-01) In this study, boron doped and undoped poly (vinyl) alcohol/bismuth-gadolina acetate (PVA/Bi-Gd) nanofibers were prepared using electrospinning technique then calcinated at 800 degrees C for 2 h. The originality of this study is the addition of boron to metal acetates. The effects of boron doping were investigated in terms of solution properties, morphological changes and thermal characteristics. The characteristics of the fibers were investigated with FT-IR, XRD, SEM and BET. The addition of boron did not ...
