The effects of ethylene-methyl acrylate-glycidyl methacrylate (E-MA-GMA) terpolymer and three types of organoclays (Cloisite (R) 15A, 25A, and 30B) on mechanical and rheological properties, and morphology of impact modified polyamide-6/montmorillonite ternary nanocomposites were investigated by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), parallel disk rheometry, melt flow index measurements, and tensile and impact tests. The materials were prepared by melt blending using a co-rotating twin-screw extruder. XRD and TEM analyses showed that exfoliated-intercalated nanocomposites were formed in both polyamide-6/Cloisite (R) 25A and Cloisite (R) 30B binary nanocomposites and in ternary systems. SEM micrographs showed that rubber domain sizes were larger in the nanocomposites than in their corresponding polyamide-6/elastomer blends. Generally, tensile strength, Young's modulus, and elongation at break decreased with the addition of elastomer to polyamide-6/organoclay binary nanocomposites. In the melt state, liquid-like behavior of polyamide-6 slightly turned to pseudo solid-like in the binary and ternary nanocomposites. (C) 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012

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.

Mechanical and optical properties of SiO2 thin films deposited on glass Simurka, Lukas; Ctvrtlik, Radim; Tomastik, Jan; Bektaş, Gence; Svoboda, Jan; Bange, Klaus (2018-09-01) The optical and mechanical properties of amorphous SiO2 films deposited on soda-lime silicate float glass by reactive RF magnetron sputtering at room temperature were investigated in dependence of the process pressure. The densities of the films are strongly influenced by the process pressure and vary between 2.38 and 1.91 g cm(-3) as the pressure changes from 0.27 to 1.33 Pa. The refractive indices of the films shift between 1.52 and 1.37, while the residual compressive stresses in the deposited films vary...
Structural and optical properties of thermally evaporated Cu-Ga-S (CGS) thin films Gullu, H. H.; IŞIK, MEHMET; Hasanlı, Nızamı (2018-10-15) The structural and optical properties of thermally evaporated Cu-Ga-S (CGS) thin films were investigated by Xray diffraction (XRD), energy dispersive X-ray spectroscopy (EDS), atomic force microscopy (AFM) and optical transmittance measurements. The effect of annealing temperature on the results of applied techniques was also studied in the present paper. EDS results revealed that each of the elements, Cu, Ga and S are presented in the films and Cu and Ga concentration increases whereas S concentration decr...
Structural and Optical Properties of Ga2Se3 Crystals by Spectroscopic Ellipsometry Güler, Işıkhan; Hasanlı, Nızamı; Babayeva, R. F. (2019-04-01) Optical and crystalline structure properties of Ga2Se3 crystals were analyzed utilizing ellipsometry and x-ray diffraction (XRD) experiments, respectively. Components of the complex dielectric function (epsilon=epsilon(1)+i epsilon(2)) and refractive index (N=n+ik) of Ga2Se3 crystals were spectrally plotted from ellipsometric measurements conducted from 1.2eV to 6.2eV at 300K. From the analyses of second-energy derivatives of epsilon(1) and epsilon(2), interband transition energies (critical points) were de...
Thermal and mechanical properties of poly(methyl methacrylate) used as dental base material Usanmaz, Ali; Turker, F; Dogan, A; Akkas, N (1998-08-15) The thermal and mechanical properties of poly( methyl methacrylate) prepared at different curing times were studied using DSC, TGA, tensile, and three-point bending test methods. The molecular weights of the polymer samples were determined from the viscosity measurements. The curing time applied for two different commercial materials, manufactured for dental use, ranged from 15 to 180 min. The samples cured for 15 and 20 min were soluble in chloroform completely, but the others were partially soluble. The i...
