Poly(ether ester) (PEE) copolymers were synthesized in a two-stage process involving transesterification and polycondensation. The synthesized copolymer and the zinc oxide (ZnO) were used in composite preparation by melt compounding. The influence of ZnO type and concentration on the morphology, thermal and mechanical properties of the composites were studied. DSC and XRD analyses indicated that crystallinity of composites was slightly reduced with ZnO content. Homogeneous dispersion of fillers in the polymer matrix was observed through morphological analyses. While in general tensile strength and elongation at break values of the composites decreased with increasing ZnO content, elastic modulus values increased with the addition of ZnO. Moreover, ZnO particles were modified with poly(N-vinyl pyrrolidone) and a slight improvement in mechanical properties was observed, respectively over the composites containing unmodified particles.

Effect of Carbon Nanotube Purification on the Electrical and Mechanical Properties of Poly(ethylene terephthalate) Composites with Carbon Nanotubes in Low Concentration Yesil, Sertan; Bayram, Göknur (Wiley, 2011-03-15) Surface properties of carbon nanotubes (CNTs) were altered by purification with nitric acid, sulfuric acid, ammonium hydroxide, and hydrogen peroxide. As-received and purified CNT-based conductive poly( ethylene terephthalate) composites were prepared with a twin-screw extruder. The effects of CNT purification on the surface properties of the CNTs and on the morphology and electrical and mechanical properties of CNT-based composites were investigated. Surface energy measurements showed that the acidic compo...
Effect of heat treatment on the stress and structure evolution of plasma deposited boron nitride thin films Anutgan, T. Aliyeva; Anutgan, M.; Wdemir, O.; Atilgan, I.; Katircioglu, B. (Elsevier BV, 2008-03-25) Boron nitride (BN) thin films are deposited at 573 K by plasma enhanced chemical vapor deposition (PECVD) with ammonia (NH3) and hydrogen diluted diborane (15% B2H6 in H-2) source gases. UV-visible and Fourier transform infrared (FTIR) spectroscopies together with surface profilometry are used for the film characterization. These films are hydrogenated (BN:H) whose hydrogen content is pursued following the 1.5 h annealing process at 748 K, 923 K and 1073 K under nitrogen atmosphere. Hydrogen escape with the...
Enzyme electrodes for determination of total phenolic capacity of red wines KIRALP, S; Çırpan, Ali; Toppare, Levent Kamil (Wiley, 2005-10-05) A tyrosinase-modified electrode, based on physical entrapment of enzyme in copolymer matrix of decanedioic acid bis(4-pyrrol-1-yl-phenyl) ester (DAPE) with pyrrole was constructed and used to investigate the total amount of phenolics in red wines. Kinetic parameters, V-max, and K-m, were determined. Also, temperature, pH optimizations, operational stability and shelf life of the enzyme electrode were examined. Surface morphologies of the films were studied by scanning electron microscope. (c) 2005 Wiley Per...
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...
Synthesis and characterization of epoxy based nanocomposites Basara, G; Yılmazer, Ülkü; Bayram, Göknur (Wiley, 2005-11-01) Epoxy-clay nanocomposites were synthesized to examine the effects of the content and type of different clays on the structure and mechanical properties of the nanocomposites. Diglycidyl ether of bisphenol-A (epoxy) was reinforced by 0.5-11 wt % natural (Cloisite Na+) and organically modified (Cloisite 3013) types of montmorillonite. SEM results showed that as the clay content increased, larger agglomerates of clay were present. Nano-composites with Cloisite 30B exhibited better dispersion and a lower degree...
