Synthesis and characterization of a flexible polymer produced from silane coupling agent (SCA) and hydroxyl terminated polybutadiene (HTPB) were performed. Mechanical properties of chemically and electrochemically prepared conducting composites synthesized from this polymer were investigated. Conductivities of the composites were also measured. Polypyrrole enhanced the mechanical properties of the chemically prepared conducting composite. Doping with iodine greatly changed the conductivity of the composite. However, the change in mechanical properties and the conductivities of the electrochemically prepared composite were not as significant when compared with the electrochemically prepared polypyrrole. Among the composites, a chemically prepared composite was highly flexible like rubber. However, the electrochemically produced composite possesses two orders of magnitude higher conductivity. Also, this composite revealed higher tensile strength and elasticity with respect to pristine polypyrrole.

Synthesis and Characterization of 2-Hydroxyethyl Methacrylate (HEMA) and Methyl Methacrylate (MMA) Copolymer Used as Biomaterial Vargun, Elif; SANKIR, MEHMET; Aran, Bengi; DEMİRCİ SANKIR, NURDAN; Usanmaz, Ali (Informa UK Limited, 2010-01-01) A series of poly(methyl methacrylate-co-hydroxyethyl methacrylate) (PMMA-co-PHEMA), copolymers were synthesized by an emulsion polymerization technique. Copolymer compositions were determined by FT-IR and 1H-NMR spectroscopy. It was found that comonomer ratios used in the recipes were comparable within the actual copolymers. Glass transition temperatures (Tg) of PMMA-co-PHEMA copolymers were varied from 119 degrees C to 100 degrees C by increasing HEMA content. Thermogravimetric analysis showed that the cop...
Synthesis and Characterization of Conducting Copolymers of Bisphenol A-Diglycidyl Ether with Thiophene Side-Groups and Pyrrole Sahmetlioglu, Ertugrul; Varol, Ramazan; Toppare, Levent Kamil; Yuruk, Huseyin (Informa UK Limited, 2009-01-01) Copolymers of bisphenol A-diglycidyl ether with thiophene side-groups and pyrrole were synthesized by electrochemical polymerization. Bisphenol A-diglycidyl ether with thiophene side-groups (DGEBATh) was obtained from the reaction between bisphenol A-diglycidyl ether (DGEBA) and thiophene-3-acetic acid. The syntheses of copolymers of DGEBATh and pyrrole were achieved electrochemically using three different supporting electrolytes, p-toluene sulfonic acid (PTSA), sodium dodecyl sulfate (SDS) and tetrabutylam...
Degradation of Poly(2-hydroxyethyl methacrylate) Obtained by Radiation in Aqueous Solution Varguen, Elif; Usanmaz, Ali (Informa UK Limited, 2010-01-01) The degradation of poly(hydroxyethyl methacrylate), PHEMA obtained by -radiation induced polymerization of HEMA in aqueous solution, was studied. The polymer was a gel type and insoluble in common organic solvents. The DSC thermogram of the polymer gave a Tg value at 88.2 degrees C and an endothermic peak showed further polymerization or crosslinking at 110-160 degrees C. The degradation observed in TGA was a depolymerization type. However, the FT-IR of TGA fragments showed no monomer, which was degraded fu...
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...
Synthesis, characterization, and electrochromic properties of conducting copolymers of 2-[(3-thienylcarbonyl)oxy]ethyl 3-thiophene carboxylate with thiophene and pyrrole Bulut, U; Alkan, S; Yilmaz, F; Yagci, Y; Toppare, Levent Kamil (Informa UK Limited, 2004-07-01) 2-[(3-Thienylcarbonyl)oxy]ethyl 3-thiophene carboxylate (TOET) was synthesized via the reaction of 3-thionylcarboxylic acid with ethylene glycol, and electrochemically polymerized with thiophene (Th) and pyrrole (Py) by using tetrabutylannnonium tetrafluoroborate (TBAFB) as the supporting electrolyte in acetonitrile (ACN). Characterization of the resulting copolymers were performed via cyclic voltammetry, FTIR, and scanning electron microscopy (SEM). Electrical conductivities are measured by the four-probe ...
