We investigated the thermal degradation characteristics of polylactide (PLA) aluminium diethylphosphinate (AlPi) composites involving SiO2, halloysite (HNT) and organically modified montmorillonite (OMMT) via direct pyrolysis mass spectrometry. Presence of nanoparticles, SiO2, HNT and OMMT affected both thermal stability and relative yields of thermal degradation products of PLA/AlPi. The transesterification reactions and interactions between PLA and AlPi were depressed in the presence of SiO2 and HNT. The increase in thermal stability detected in the presence of OMMT was associated with generation of cross-linked structure as a consequence of reactions between the organic modifier of montmorillonite, the carbonyl groups of PLA and phosphinates.

Effect of expandable graphite on flame retardant, thermal and mechanical properties of thermoplastic polyurethane composites filled with huntite&hydromagnesite mineral Guler, Turkan; Tayfun, Umit; Bayramlı, Erdal; DOĞAN, Mehmet (2017-01-10) The effect of expandable graphite (EG) was studied on the flame retardant, thermal and mechanical properties of thermoplastic polyurethane (TPU) containing huntite&hydromagnesite (HH). According to the flammability tests results, the synergistic interaction was observed between HH and EG. The maximum limiting oxygen index (LOI value was observed at a ratio of 1:1 (HH:EG) and the highest vertical burning test (UL-94) rating of V0 was observed at a ratios of 4:1, 3:2 and 1:1. The synergistic interaction betwe...
Effect of preparation parameters on the performance of conductive composite gas separation membranes Gulsen, D; Hacarloglu, P; Toppare, Levent Kamil; Yılmaz, Levent (2001-02-15) Mixed matrix composite membranes of a conducting polymer, polypyrrole (PPy), and an insulating polymer, polybisphenol-A-carbonate (PC) were prepared by a combined in-situ polymerization and solvent evaporation. Mixed matrix composite membranes were synthesized to combine the good gas transport properties of conductive polymer, PPy, with good mechanical properties of PC.
Effects of halloysite nanotubes on the mechanical, crystallization, and weathering behaviour of polylactide Kaygusuz, İlker; Kaynak, Cevdet; Özkan, Necati; Department of Micro and Nanotechnology (2014) The purpose of the first part of this thesis was to investigate the usability of industrially friendly twin screw extruder melt compounding method and injection molding melt shaping method to produce polylactide (PLA) / halloysite nanotube (HNT) composites for engineering applications. One of the main problems of PLA to be used in engineering applications is its inherent brittleness. Therefore, another goal was to reveal the effects of HNTs on the significant thermal and mechanical engineering properties of...
Effect of clay on crude oil combustion by thermal analysis techniques Kök, Mustafa Verşan (Springer Science and Business Media LLC, 2006-05-01) This research was aimed to investigate the role of clay on the combustion and kinetic behavior of crude oils in limestone matrix. For this purpose, simultaneous TG (thermogravimetry) and DTA (differential thermal analysis) experiments were performed at three different heating rates as 10-15 and 20 degrees C min(-1), respectively. A uniform trend of decreasing activation energies was observed with the addition of clay. It was concluded that clays surface area affects the values of Arrhenius constant, while i...
Effect of metal oxide on light oil combustion - TA and kinetic analysis Kök, Mustafa Verşan (Springer Science and Business Media LLC, 2003-01-01) Simultaneous thermogravimetry (TG) and differential thermal analysis (DTA) were applied to light crude oil combustion in the presence and absence of metal oxide. In crude oil-limestone mixture, three main transitional stages are detected. These are distillation, low-temperature oxidation (LTO) and high temperature oxidation (HTO) regions respectively. In the case of experiments with Fe(III)chloride at different amounts, the shape of TG-DTA curve is changed considerably. Kinetic parameters of the samples are...
