Direct pyrolysis mass spectrometry technique was applied to investigate the characteristics of polylactide, (PLA) nanofibers containing organically modified montmorillonites, Cloisite 15A, (C15A) Cloisite 20A, (C20A) and Cloisite 30B, (GOB) prepared by electrospinning. As the amount of Cloisite present in the composites was increased, the fiber diameters became slightly narrower compared to neat PLA fiber due to the presence of quaternary ammonium salt as organic modifier increasing electrical conductivity. The diameters of the fibers were smallest for PLA/C15A composite and largest for PLA/C30B composite. This behavior was directly related to the amount of organic modifier present in the nanoclays. Significant increase in the thermal stability of PLA composite nanofibers was detected compared to not only neat PLA and PLA fiber but also compared to PLA/organoclay composites and associated with the increase in extent of delamination evidenced by pyrolysis mass spectrometry results.

Polylactide/organically modified montmorillonite composites; effects of organic modifier on thermal characteristics Ozdemir, Esra; Öztürk, Yurdagül; Hacaloğlu, Jale (2016-12-01) The effects of interspace distance and the possible chemical interactions between PLA and the organic modifier of montmorillonites, Cloisite 15A, 20A and 30B on thermal degradation of PLA in the absence and presence of water vapor were investigated by direct pyrolysis mass spectrometry, (DP-MS) in addition to XRD, TEM, DSC, TGA analyses. The DP-MS results clearly showed that the way in which the polymer was incorporated into the nanocomposite strongly depends on the mixing technique, the interspacing betwee...
Pyrolysis of poly(phenylene vinylene)s with polycaprolactone side chains Nur, Yusuf; Çolak, Demet; Cianga, Ioan; Yagci, Yusuf; Hacaloğlu, Jale (2008-05-01) The thermal degradation characteristics of a new macromonomer poly(epsilon-caprolactone) with central 4,4'-dicarbaldehyde terphenyl moieties and poly(phenylene vinylene)s with well defined (E-caprolactone), (PPV/PCL) as lateral substituents were investigated via direct pyrolysis mass spectrometry. The unexpectedly high thermal stability of the macromonomer was attributed to intermolecular acetylation of benzaldehyde yielding a hemiacetal and causing a crosslinked structure during the pyrolysis. Increased th...
Pyrolysis of of poly(methy methacrylate) copolymers Ozlem-Gundogdu, Suriye; Gurel, Evren Aslan; Hacaloğlu, Jale (2015-05-01) In this work, thermal degradation of copolymers of poly(methy methacrylate) namely, poly(methyl methacrylate-co-n-butyl acrylate), P(MMA-co-nBu), poly(methyl methacrylate-co-n-benzyl methacrylate) P(MMA-co-BzMA, and poly(methyl methacrylate-co-isobornyl acrylate), P(MMA-co-IBA) were investigated via direct pyrolysis mass spectrometry. It was determined that whether an available gamma-H with respect to the carbonyl groups is present or not determines the thermal degradation mechanisms of polyacrylates and po...
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...
Thermal degradation of Polylactide/Poly(ethylene glycol) fibers and composite fibers involving organoclay Ozdemir, Esra; Hacaloğlu, Jale (2018-01-01) In this study, electrospun fibers of melt blended poly(lactic acid) and poly(ethylene glycol), (PLA)-PEG blends involving 10, 15 and 20 wt% PEG and their corresponding composites with organically modified montmorillonite, Cloisite 30B were prepared and characterized by x-ray diffraction, differential scanning calorimetry, thermogravimetry and direct pyrolysis mass spectrometry techniques. The narrower fiber diameters observed for the PLA-PEG fibers involving organoclay compared to the corresponding neat fib...
