Conductive and flexible polydimethylsiloxane (PDMS)/polypyrrole (PPy) composites were synthesized electrochemically. Electrochemical syntheses were performed at +1.10 V by using p-toluene sulfonic acid (PTSA) as supporting electrolyte and water as solvent. Composites were characterized by cyclic voltammetry, thermogravimetric analysis, differential scanning calorimetry, scanning electron microscopy, and Fourier transform infrared spectroscopy. Conductivity measurements and mechanical tests were also performed. The observed conductivities were in the range of 3.5-7.6 S/cm, indicating that the conductivities of PDMS/PPy composites and that of pure PPy were in the same order of magnitude. Tensile tests revealed that higher percent elongation was obtained by the addition of PDMS. Highly flexible and foldable PDMS/PPy composites were successfully synthesized, which have high conductivities and unproved mechanical properties. (C) 2004 Wiley Periodicals, Inc.

Preparation and Comparison of Two Electrodes for Supercapacitors: Pani/CNT/Ni and Pani/Alizarin-Treated Nickel Koysuren, Ozcan; Du, Chunsheng; Pan, Ning; Bayram, Göknur (Wiley, 2009-07-15) Polyaniline in emeraldine form was synthesized in the presence of multiwalled carbon nanotubes (CNTs), and the electrochemical capacitance performance of thus formed composite as electrode material has been Studied. The polyaniline/carbon nanotubes (Pani/CNT) composite is found to result in a higher specific capacitance than that of either composite constituent, attributable to the double-layer capacitance behavior of the nanotubes in the Pani/CNT system. However, once assembled into a two-electrode cell, l...
Dynamic mechanical properties of dental base material reinforced with glass fiber Karacaer, O; Dogan, A; Dogan, OM; Usanmaz, Ali (Wiley, 2002-08-22) Dynamic mechanical properties of poly(methyl methacrylate) (PMMA) reinforced with glass fibers were investigated. The composite used as dental base material contained other additives for different purposes to give the same appearance as natural dentals. The fiber-polymer bonding and orientation of fibers in polymer matrix are very important in the application of the product. To see that, the fibers were treated with silane and compared with untreated fibers. The commercial polymer and monomer used were the ...
Chain-extended bismaleimides .1. A study of chain-extended bismaleimides as matrix elements in carbon fiber composites Yerlikaya, Z; Erinc, NK; Oktem, Z; Bayramlı, Erdal (Wiley, 1996-01-18) A series of chain-extended bismaleimide resins as matrix elements in carbon fibers were cured and characterized in terms of their thermal and thermomechanical properties. The cured resins were stable up to 430 degrees C and EDABMI/MDA has the highest T-g value and the lowest loss modulus value. To understand the compatibility and the degree of adhesion between the resin and the fiber, their surface properties were determined in terms of the surface energy component and single-fiber pull-out tests. The surfa...
Kinetic study of the reaction between hydroxyl-terminated polybutadiene and isophorone diisocyanate in bulk by quantitative FTIR spectroscopy Kincal, D; Özkar, Saim (Wiley, 1997-12-05) A kinetic study of the reaction between a hydroxyl-terminated polybutadiene (HTPB) and isophorone diisocyanate (IPDI) was carried out in the bulk state by using quantitative Fourier transform infrared(FTIR) spectroscopy. The reaction is shown to obey a second-order rate law, being first order in both the HTPB and IPDI concentrations. The activation parameters obtained from the evaluation of kinetic data are Delta H-double dagger = 41.1 +/- 0.4 kJ mol, Delta S-double dagger = -198 +/- 2 J K-1 mol(-1) and E-a...
Mechanical properties of soft liner-poly(methyl methacrylate)-based denture material Usanmaz, Ali; Latifoglu, MA; Dogan, A; Akkas, N; Yetmez, M (Wiley, 2002-07-18) In this study, the mechanical properties of two different permanent soft lining materials and their bonding to poly(methyl methacrylate) (PMMA) were compared. Both of the soft liners were heat-cured commercial materials. The polymerization was carried out by conventional methods suggested by manufacturer, and the curing was done at the temperature of boiling water for 5, 15, 25, and 35 min. The sample groups were tested in the computer-aided tensile-testing machine at a rate of 2 mm/min. The slow rate helps...
