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), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) techniques. When both PPy and PAn existed in the films, the major contribution to the conductivity was due to the PPy component. PDMS/PPy/PAn films were more conductive than PDMS/PAn/PPy films similar to their binary counterparts without PDMS. When PPy was coated over PAn, thermally more stable films were obtained than the films synthesized in reverse order. The characterization tests implied the formation of chemically bounded new structures such as crosslinking copolymer structures. SEM microphotographs of PDMS/PAn/PPy films indicated a clear double layer structure. Hence, changing the order of coating had significant effects on the structure and properties of films.

Electrochemical preparation and characterization of carbon fiber reinforced poly (dimethyl siloxane)/polythiophene composites: electrical, thermal and mechanical properties Sankir, M; Kucukyavuz, S; Kucukyavuz, Z (Elsevier BV, 2002-05-10) 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 ha...
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...
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.
Donor acceptor type neutral state green polymer bearing pyrrole as the donor unit Celebi, Selin; Balan, Abidin; Epik, Bugra; Baran, Derya; Toppare, Levent Kamil (Elsevier BV, 2009-07-01) A new neutral state green polymer, poly (2,3-bis(4-tert-butylphenyl)-5,8-di(1H-pyrrol-2-yl) quinoxaline) (PTBPPQ) was synthesized and its potential use as an electrochromic material was investigated. Spectroelectrochemistry studies showed that polymer reveals two distinct absorption bands as expected for a donor-acceptor type polymer, at 408 and 745 nm. In addition, polymer has excellent switching properties with satisfactory optical contrasts and very short switching times. Outstanding optical contrast in ...
Properties of YBCO superconductors prepared by ammonium nitrate melt and solid-state reaction methods Sozeri, Huseyin; Ozkan, Husnu; Ghazanfari, Nader (Elsevier BV, 2007-01-31) Ceramic YBCO superconductors were prepared by: (1) ammonium nitrate melt, (2) solid-state reaction methods and the properties of the samples obtained were compared. Under the same annealing conditions single phase YBCO was synthesized at a lower temperature by the former method. Moreover, at 900 degrees C Y-123 phase and the initially adjusted Y-211 additive could be formed using ammonium nitrate melt, but not with the solid-state method which leads Y-123 at a higher temperature (950 degrees C) without Y-21...
