The synthesis was performed by the electropolymerization of thiophene on a poly(dimethylsiloxane) (PDMS)-coated platinum electrode at 2.2 V with tetrabutylammoniumtetrafloroborate (TBAFB) as a supporting electrolyte and with acetonitrile as a solvent. The characterization of the PDMS-polythiophene (Pth) composites was carried out with cyclic voltammetry, Fourier transform infrared (FTIR), scanning electron microscopy (SEM), differential scanning calorimetry (DSC), thermogravimetric analysis, and conductivity measurements. The observed conductivities of the PDMS composites were 2.2-5.2 S/cm. The conductivity of Pth did not change appreciably with the addition of up to 30% insulating PDMS, but its processability improved. FTIR, SEM, and DSC studies showed the existence of a strong interaction, rather than physical adhesion, between PDMS and Pth. Highly flexible and foldable PDMS-Pth composites were obtained.

Synthesis and Characterization of a New Conducting Polymer Based on 4-(2,5-di-2-thiophen-2-yl-pyrrol-1-yl)-phthalonitrile
Yavuz, Arzu; Bezgin, Buket; Önal, Ahmet Muhtar (Wiley, 2009-12-05)
A new conducting polymer was synthesized by electrochemical polymerization of 4-(2,5-di-2-thiophen-2-yl-pyrrol-1-yl)-2-phthalonitrile (SNS-PN). Electrochemical polymerization of SNS-PN was performed in acetonitrile/0.2M LiClO4 solvent/electrolyte couple. Characterizations of the resulting polymer P(SNS-PN) were carried out by cyclic voltammetry, UV-vis, and Fourier transform infrared (FTIR) spectroscopic techniques. Spectroelectrochemical studies revealed that P(SNS-PN) has an electronic band gap of 2.45 eV...
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...

New pi-conjugated polymers containing dithieno(3,2-b: 2',3'-d) pyrrole (DTP) were successfully synthesized via electropolymerization. The effect of structural differences on the electrochemical and optoelectronic properties of the 4-[4H-dithieno(3,2-b: 2',3'-d) pyrrol-4-yl] aniline (DTP-aryl-NH2), 10-[4H-dithiyeno(3,2-b: 2',3'-d) pirol-4-il] dekan-1-amine (DTP-alkyl-NH2), and 1,10-bis[4H-dithieno(3,2-b:2',3'-d) pyrrol-4-yl] decane (DTP-alkyl-DTP) were investigated. The corresponding polymers were characteri...

Bingol, B; Camurlu, P; Toppare, Levent Kamil (Wiley, 2006-05-05)
Copolymer of thiophen-3-yl acetic acid 4-pyrrol-1-yl phenyl ester (TAPE) with N-methylpyrrole (NMPy) was synthesized by potentiostatic electrochemical polymerization in acetotiitrile-tetrabutylammonium tetrafluoroborate solvent-electrolyte couple. The chemical structures were confirmed via Fourier transform infrared spectroscopy (FTIR), cyclic voltammetry (CV), and UV-vis spectroscopy. Electrochromic and spectroelectrochemical properties of poly(TAPE-co-NMPy) [P(TAPE-co-NMPy)] were investigated. Results sho...
Synthesis and characterization of multi-hollow opaque polymer pigments
Asmaoglu, Serdar; Gündüz, Güngör; MAVİŞ, BORA; Colak, Uner (Wiley, 2016-08-05)
A new generation multihollow opaque polymer pigment was synthesized by suspension polymerization of water-in-oil-in-water emulsion method, where methyl methacrylate and ethylene glycol dimethacrylate monomer mixture was used as oil phase. The effects of surfactant and cosurfactant composition in terms of hydrophilic/lipophilic balance on the stability of the water-in-oil emulsion and the size of water droplets were studied. Low droplet sizes and the optimum stability were obtained with Span 80&Tween 80 surf...
