The effects of component concentrations and addition order of the components, on the final properties of ternary nanocomposites composed of amorphous poly (ethylene terephthalate) matrix, organically modified clay, and an ethylene / methyl acrylate / glycidyl methacrylate (E-MAGMA) terpolymer were studied. All formulations were prepared by melt compounding of the components with a two-step mixing procedure in a corotating twin-screw extruder. Considering the X-Ray Diffraction, SEM, impact and strain at break results, the best sequence of component addition was the one in which PET was first compounded with E-MA-GMA, later this mixture was compounded with the organoclay in a subsequent run. In this mixing order, the polymer-impact modifier matrix mixture prepared in the first extrusion run has higher melt viscosity than pure PET, thus this matrix can apply high shear stresses on the clay particles and delaminate the clay layers resulting in the best mechanical properties.

Effects of Addition Order of the Components on Polyamide-6/Organoclay/Elastomer Ternary Nanocomposites Isik-Gulsac, Isil; YILMAZER, ÜLKÜ; Bayram, Göknur (2013-03-01) The effects of addition order of the components for ethyleneglycidyl methacrylate (E-GMA) copolymers and two types of organoclays (Cloisite (R) 15A and Cloisite (R) 30B) on morphology and mechanical properties of polyamide-6/elastomer/organoclay ternary nanocomposites were investigated by x-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM) analyses, melt flow index (MFI) measurements, differential scanning calorimetry (DSC), and tensile and impact tests. Four ...
Effect of silver encapsulation on the local structure of titanosilicate ETS-10 GALIOGLU, Sezin; ZAHMAKIRAN, Mehmet; Kalay, Yunus Eren; Özkar, Saim; Akata, Burcu (2012-09-01) Silver(0) nanoparticles stabilized by titanosilicate (ETS-10) framework were synthesized by following a simple two step procedure involving the incorporation of silver(I) (Ag+) ions into ETS-10 matrix via ion-exchange with extra framework Na+ and K+ cations followed by their reduction with sodium borohydride (NaBH4) in aqueous medium all at room temperature. Silver(0) nanoparticles dispersed in the ETS-10 matrix were collected as gray powders and characterized by using advanced analytical methods including ...
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.
Influence of oxygen plasma modification on surface free energy of PMMA films and cell attachment Ozcan, Canturk; Zorlutuna, Pinar; Hasırcı, Vasıf Nejat; Hasırcı, Nesrin (2007-10-04) For any biomaterial placed into a biological medium, the surface properties of the material, such as porosity, crystallinity, presence and distribution of electrical charge and functional groups are very critical parameters that determine the acceptance or rejection of the material. Applications, especially tissue engineering require some surface modifications at the molecular level without disturbing the bulk properties of the implants in order to enhance the cell attachment on the material. An appropriate...
EFFECT OF ION ASSOCIATION ON THE PROPERTIES OF IONOMERS OBTAINED FROM METHYL-METHACRYLATE METHACRYLIC-ACID COPOLYMER KOCAK, HI; ARAS, L (Elsevier BV, 1990-07-01) The solution behaviour of Na, Ba, Zn and Al ionomers of methyl methacrylate-methacrylic acid copolymer (P(MMA-MAA)) with different ion contents has been studied by viscosity and dipole moment measurements. Two solvents with different character are chosen for viscosity measurements: dioxane (ε = 2.22) and acetone (ε = 20.7). The expected polyelectrolyte behaviour of the ionomers in acetone is reflected by the viscometric measurements. Mean squared dipole moment 〈μ2〉 values are calculated over a temperature r...
