Block and random copolymers having 3-methyl thienylmethacrylate and 6-(4-cyanobiphenyl-4'-oxy) hexyl acrylate moieties were utilized as precursor polymers in this study. Electrochemical copolymerizations were performed in the presence of thiophene or pyrrole in acetonitrile-tetrabutylammonium tetrafluoroborate (TBAFB) at constant potential. The characterizations were performed by cyclic voltammetry (CV), fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermal gravimetry analysis (TGA), scanning electron microscopy (SEM), conductivity measurements. Electrochromic properties of the resultant conducting copolymers were investigated by spectroelectrochemistry and colorimetry studies. It was observed that, variation in the copolymer type or composition of the precursor polymer resulted in stern effects on surface morphology, spectroelectrochemistry, color and conductivity of the resultant graft copolymer.

Reactive extrusion of poly(ethylene terephthalate)-(ethylene/methyl acrylate/glycidyl methacrylate)-organoclay nanocomposites Alyamac, Elif; Yılmazer, Ülkü (Wiley, 2007-04-01) This study was conducted to investigate the effects of component concentrations and addition order of the components on the final properties of ternary nanocomposites composed of poly(ethylene terephthalate), organoclay, and an ethylene-methyl acrylate-glycidyl methacrylate (E-MA-GMA) terpolymer acting as an impact modifier for PET. In this context, first, the optimum amount of the impact modifier was determined by melt compounding binary PET-terpolymer blends in a corotating twin-screw extruder. The amount...
Immobilization of Tyrosinase in Poly(2-thiophen-3-yl-alkyl ester) Derivatives ÇAMURLU, PINAR; Kayahan, Senem; Toppare, Levent Kamil (Informa UK Limited, 2008-01-01) In this study, construction of novel biosensors for the determination of phenolic compound was performed via immobilization of tyrosinase during the electrochemical synthesis of conducting block copolymers of 2-thiophen-3-yl-alkyl ester derivatives with 3,4-ethylenedioxythiophene and synthesis of poly(3,4-ethylenedioxythiophene) (PEDOT). The resultant biosensors were characterized in terms of their maximum reaction rates, Michaelis-Menten constants (Km), temperature and pH stabilities. All the copolymer mat...
Impact modified polyamide-6/organoclay nanocomposites: Processing and characterization Isik, Isil; YILMAZER, ÜLKÜ; Bayram, Göknur (Wiley, 2008-02-01) The effects of melt state compounding of ethylene-butyl acrylate-maleic anhydride (E-BA-MAH) terpolymer and/or three types of organoclays (Cloisitel(R) 15A, 25A, and 3013) on thermal and mechanical properties and morphology of polyamide-6 are investigated. E-BA-MAH formed spherical domains in the materials to which it is added, and increased the impact strength, whereas the organoclays decreased the impact strength. In general, the organoclays increased the tensile strength (except for Cloisite 15A), Young'...
Dual type complementary colored polymer electrochromic devices based on conducting polymers of poly(hexanedioic acid bis-(2-thiophen-3-yl-ethyl ester) Camurlu, P; Toppare, Levent Kamil (Informa UK Limited, 2006-03-01) In this study, dual type polymer electrochromic devices (ECDs) based on homopolymer and copolymer of hexanedioic acid bis-(2-thiophen-3-yl-ethyl ester) with 3,4-ethylene dioxythiophene (EDOT) were constructed, where PEDOT functioned as the cathodically coloring layer. Spectroelectrochemistry, switching ability, stability, open circuit memory and color of the devices were investigated. Results of the kinetic studies showed these devices exhibit switching times around 1.8 s with an optical contrast of 24-25.3...
Influences of aminosilanization of halloysite nanotubes on the mechanical properties of polyamide-6 nanocomposites Erdogan, Ali Riza; Kaygusuz, Ilker; Kaynak, Cevdet (Wiley, 2014-07-01) The main purpose of this study was to explore effects of silanization of halloysite nanotubes (HNT) on the mechanical properties of polyamide 6 by using aminopropyltriethoxysilane. Effects of two silanization parameters; initial silane concentration and pH of reaction solution were also investigated. Nanocomposites were compounded via melt mixing method in a twin-screw extruder, while specimens were shaped by injection molding. Formation of aminosilane molecules on the edges and defected surfaces of HNTs we...
