Poly(ethylene terephthalate)/Carbon Nanotube Composites Prepared With Chemically Treated Carbon Nanotubes
Yesil, Sertan; Bayram, Göknur (Wiley, 2011-07-01)
Surfaces of multiwalled carbon nanotubes (CNT) were functionalized by treatment with strong acid mixture (purification) followed by modification with sodium dodecyl sulfate, poly(ethylene glycol) (PEG), and diglycidyl ether of Bisphenol A (DGEBA). Poly(ethylene terephthalate) (PET)-based conductive polymer composites were prepared by using these CNT by means of melt mixing with a twin screw extruder. Amount of carboxylic acid groups on the CNT surface increased after acid treatment but decreased with surfac...
Polycarbonate based zeolite 4a filled mixed matrix membranes: preparation, characterization and gas separation performances
Şen, Değer; Yılmaz, Levent; Department of Chemical Engineering (2008)
Developing new membrane morphologies and modifying the existing membrane materials are required to obtain membranes with improved gas separation performances. The incorporation of zeolites and low molecular-weight additives (LMWA) into polymers are investigated as alternatives to modify the permselective properties of polymer membranes. In this study, these two alternatives were applied together to improve the separation performance of a polymeric membrane. The polycarbonate (PC) chain characteristics was a...
Polyethylene oxide-induced flocculation of dolomite/clay/borax-containing suspensions
Çırak, Mustafa; Hoşten, Çetin; Department of Mining Engineering (2014)
Kırka borax formation in Turkey is the largest borate deposit in the world. However, this important boron mineral is associated with significant amount of dolomite and clay gangue. When the run-of-mine ore is processed via simple crushing/washing/scrubbing methods, these gangues are discharged from the concentrator in the form of a stable colloidal suspension. The resultant dolomite/clay/borax-containing tailing creates a critical bottleneck threatening safe and sustainable borax production. To analyze this...
Polyfluorene Thin Films Synthesized by a Novel Plasma Polymerization Method
GÖKTAŞ, HİLAL; Mansuroğlu, Doğan; ATALAY, BETÜL; Bilikmen, Sinan; KAYA, İSMET (2012-02-01)
The synthesis of polyfluorene (PF) thin films by simultaneously superposing a continuous and pulsed discharge and the characterizations of these samples are presented. The double discharge plasma system is constructed by superposing two discharges; namely, a low pressure dc glow one and a high current pulsed one. The fluorene monomer in powder form was vaporized in the system at argon plasma without any modification, at 0.5 mbar operating pressure. The structure of the thin films was investigated via XPS, U...
Poly(lactic acid) blends, composites and fibers and direct pyrolysis mass spectrometry for nanoclay composites
Özdemir, Esra; Hacaloğlu, Jale; Kayran İşçi, Ceyhan; Department of Polymer Science and Technology (2017)
In the first part of this study, poly(lactic acid)-poly(ethylene glycol), PLA-PEG, blends, composites and electrospun fibers of PLA and PLA composites, PLA-PEG blends and PLA-PEG, blends composites were prepared and characterized. X-ray Diffractometer (XRD), Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Gel Permeation Chromatography (GPC), Simultaneous Thermal Analyzer (STA) and Direct Pyrolysis Mass Spectrometer (DP-MS) techniques were used for characterization studies. Both T...
