A series of polydimethylsiloxane (PDMS)/polythiophene (Pth)/carbon fiber (CF) composites was synthesized by electrochemical polymerization using tetrabutylammoniumtetrafluoroborate (TBAFB) as supporting electrolyte and acetonitrile as solvent. Composites were characterized by TGA, SEM, and mechanical tests and conductivity measurements. Conductivities of composites were in the range of 25 S/cm. SEM studies show that CF were coated by PDMS/Pth matrix and well oriented in the matrix. In mechanical tests it has been observed that higher percent elongation was obtained by increasing PDMS content whereas tensile strength and modulus of composites increases with increasing CF content.

Conducting polymers of succinic acid bis-(2-thiophen-3-yl-ethyl)ester and their electrochromic properties SACAN, L; Çırpan, Ali; CAMURLU, P; Toppare, Levent Kamil (Elsevier BV, 2006-02-01) The homopolymer and copolymer of succinic acid bis-(2-thiophen-3-yl-ethyl)ester with thiophene were achieved via constant potential electrolysis in the presence of tetrabutylammonium tetrafluoroborate as the supporting electrolyte, and acetonitrile/borontrifluoride ethylether (ACN/BFEE) (10:2 v/v) solvent mixture. The characterizations of both homopolymer (PSATE) and copolymer P(SATE-co-Th) were achieved by various techniques including cyclic voltammetry (CV), Fr-IR, scanning electron microscopy (SEM) and U...
ELECTRICALLY CONDUCTIVE POLY(METHYL METHACRYLATE-G-PYRROLE) VIA CHEMICAL OXIDATIVE POLYMERIZATION STANKE, D; HALLENSLEBEN, ML; Toppare, Levent Kamil (Elsevier BV, 1993-03-22) Methyl methacrylate (MMA) and 2-bromoethyl methacrylate (BEMA) were copolymerized and the reactivity ratios of the monomers were determined. A pyrrole moiety was introduced into the copolymer via polymer analogous reaction and grafting between this molecule and pyrrole was achieved by chemical oxidative polymerization of pyrrole with iron-(III) chloride. Conductivities of 10(-2) S/cm were measured.
Conductive copolymers of polyaniline, polypyrrole and poly (dimethylsiloxane) Cakmak, G; Kucukyavuz, Z; Kucukyavuz, S (Elsevier BV, 2005-05-31) Two step electrochemical polymerization method was used to obtain various conductive homopolymers, composites and copolymers of Polyaniline (PAn), Polypyrrole (PPy) and Poly(dimethylsiloxane) (PDMS). PAn/PPy, PDMS/PAn/PPy, PPy/PAn and PDMS/PPy/PAn conductive polymer films were synthesized with different compositions and their properties were compared. Films were characterized by conductivity measurements, cyclic voltammetry (CV), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), sca...
CONDUCTING POLYMERS OF ANILINE .1. ELECTROCHEMICAL SYNTHESIS OF A CONDUCTING COMPOSITE DOGAN, S; Akbulut, Ural; Toppare, Levent Kamil (Elsevier BV, 1992-11-01) We describe an electrochemical synthesis of a conducting composite of polyaniline. Poly(bisphenol A carbonate) was used as the insulating polymer matrix. Composite characterization was made using FT-IR, SEM and DSC data. The conductivities of the composites seemed to be in the order of pure polyaniline as prepared by the same method. Moreover, the above-mentioned methods reveal that the resultant composites have different properties compared to a simple mechanical mixture of the two polymers.
Electrochemical polymerization of 9-fluorenecarboxylic acid and its electrochromic device application Bezgin, Buket; CİHANER, ATİLLA; Önal, Ahmet Muhtar (Elsevier BV, 2008-09-01) Poly(9-fluorenecarboxylic acid) (PFCA) was synthesized by electrochemical oxidation of 9-fluorenecarboxylic acid (FCA) using a mixture of nitromethane and boron trifluoride diethyl etherate as the solvent and tetrabutylammonium tetrafluoroborate as the supporting electrolyte. An insoluble and conducting brownish-orange film was deposited on the electrode surface, both during repetitive cycling and constant potential electrolysis at 1.15 V. Characterization of the polymer film has been carried out using Four...
