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.

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...
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 ANILINE .2. A COMPOSITE AS A GAS SENSOR DOGAN, S; Akbulut, Ural; YALCIN, T; SUZER, S; Toppare, Levent Kamil (Elsevier BV, 1993-09-01) The gas sensing ability of electrochemically prepared pure polyaniline and polyaniline-poly(bisphenol-A carbonate) films is investigated. The responses of the composite films to several vapours are more well defined and reproducible compared to the pure conducting polymer. The changes in resistance as determined via the two-probe technique are well defined down to a level of 0.025% vol./vol. ammonia. The possible reason for such a difference is discussed. The structure of the composite is examined through p...
Phonon dispersions and elastic constants of disordered Pd-Ni alloys Kart, SO; Tomak, Mehmet; Cagin, T (Elsevier BV, 2005-01-31) Phonon frequencies of Pd-Ni alloys are calculated by molecular dynamics (MD) simulation. Lattice dynamical properties computed from Sutton-Chen (SC) and quantum Sutton-Chen (Q-SC) potentials as a function of temperature are compared with each other. We present all interatomic force constants up to the 8th nearest-neighbor shell obtained by using the calculated potential. Elastic constants evaluated by two methods are consistent with each other. The transferability of the potential is also tested. The result...
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.
