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 rings. Thermal decomposition of P2VP blocks was started by loss of pyridine units leaving an unsaturated and/or crosslinked polymer backbone that degraded at relatively high temperatures. Incorporation of Cr metal did not noticeably influence thermal behavior of PS and PI blocks. However, increase in thermal stability of PMMA block was detected and associated with inhibition of the interactions between carbonyl groups of MMA chains with nitrogen atom of pyridine ring as a consequence of coordination to metal.

Preparation of pnzt thin films by solution deposition and their characterization Kayasü, Volkan; Özenbaş, Ahmet Macit; Department of Metallurgical and Materials Engineering (2008) The aim of this study is to produce Nb doped PZT thin films and then investigate the effects of Nb+5 ion on the structural, dielectric and ferroelectric properties. Niobium (Nb) doped lead zirconate titanate thin films (PNZT) were produced by solution deposition with nominal compositions, Pb(1-0.5x)(Zr0.53Ti0.47)1-xNbxO3 where x = 0.00 - 0.07. Single and multi-layered films were deposited onto (111)-Pt/Ti/SiO2/Si-(100) substrates by spin coating. PZT compositions near the morphotropic phase boundary (MPB) w...
Synthesis, characterization and electrochromic properties of copolymer of 3-{[4-(thien-3-yl-methoxy)phenoxy]methyl} thiophene with thiophene Erden, Ayca; Sahin, Elif; Gullu, Mustafa; Toppare, Levent Kamil (Elsevier BV, 2006-08-01) (3- {[4-(Thien-3-yl-methoxy)phenoxy]methyl} thiophene) (TMPMT) was synthesized via the reaction of 3-bromomethyl-thiophene with hydroquinone and characterized by nuclear magnetic resonance (NMR) and Fourier transform infrared spectroscopy (FTIR). Electrochemical copolymerization of TMPMT with thiophene in acetonitrile/boron trifluoride diethyl etherate (AN/BFEE) solvent mixture was achieved using tetrabutylammonium tetrafluoroborate (TBAFB) as the supporting electrolyte. Resulting copolymer was characterize...
Poly(methyl methacrylate) nanocomposites involving aromatic diboronic acid Goktas, Muberra; Hacaloğlu, Jale (2019-12-01) In this work, poly(methyl methacrylate), PMMA, composites involving various amounts of aromatic diboronic acid, BDBA, in the absence and presence of organically modified montmorillonite, Cloisite 30B, C30B, were prepared and characterized by X-ray diffraction, transmission electron microscopy, thermogravimetry, and direct pyrolysis mass spectrometry analyses. Morphologic analyses indicated homogenous dispersion of additives in PMMA matrix. Increase in thermal stability of PMMA was observed as the amount of ...
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...
Poly(methyl methacrylate) organoclay composites; interactions of organic modifier with the polymer effecting thermal degradation behavior Ozdemir, Esra; Hacaloğlu, Jale (2017-10-01) In this work, poly(methyl methacrylate), PMMA, and its composites involving montmorillonites modified with different quaternary ammonium salts were prepared and characterized by X-ray Diffraction, XRD, Transmission Electron Microscopy, TEM, Thermogravimetry, TGA and direct pyrolysis mass spectrometry, DPMS. Increase in the interlayer spacing of the silicate layers compared to the corresponding organically modified clay was detected in X-ray diffractograms for all the PMMA composites in accordance with TEM r...
