Conducting polymer composites: Polypyrrole and poly(vinyl chloride vinyl acetate) copolymer

Balci, N
Bayramli, E
Toppare, Levent Kamil
Composites of a polypyrrole (PPy) and poly(vinyl chloride-vinyl acetate) copolymer (PVC-PVA) were prepared both chemically and electrochemically. An insulating polymer was retained in the blend and the thermal stability of the polymer was enhanced by polymerizing pyrrole into the host matrix in both cases. The composites prepared electrochemically gave the best results in terms of conductivity and air stability. (C) 1997 John Wiley & Sons, Inc.

Kurbanova, RA; Mirzaoglu, R; Akovali, G; Rzaev, ZMO; Karatas, I; Okudan, A (Wiley, 1996-01-10)
Polystyrenes with different molecular weights were chemically modified with maleic anhydride by use of certain cationic catalysts of Lewis acid type (BF3 . OEt(2), AlCl3, TiCl4, ZnCl2, FeCl3, and SnCl4) in chloroform. The effects of molecular weight of polystyrene, as well as type of Lewis acid used, on properties and structure of products were investigated. The interrelation between the molecular weight of polystyrene and content of carboxyl groups in the products was made. A direct relationship between th...
Conducting copolymers of polytetrahydrofuran and their electrochromic properties
Unur, E; Toppare, Levent Kamil; Yagci, Y; Yilmaz, F (Wiley, 2005-03-05)
Living polytetrahydrofuran (PTHF) was terminated with sodium thiophene methonate to yield a polymer with a thiophene group at one end. Copolymerizations of PTHF with pyrrole and thiophene were achieved in water-p-toluene sulfonic acid and acetonitrile-tetrabutylammonium tetrafluoroborate (TBAFB) solvent-electrolyte couples via constant potential electrolyses. Characterizations of the samples were performed by NMR, cyclic voltammetry, FT-IR, thermal analyses, and scanning electron microscopy. Electrical cond...

BOZKURT, AYHAN; Parlak, Mehmet; Ercelebi, C; Toppare, Levent Kamil (Wiley, 2002-07-05)
Conducting polymers of polysiloxane-polypyrrole were Synthesized by electropolymerization of the pyrrole monomer through pyrrole moieties in N-pyrrole-terminated polysiloxanes. Sodium paratoluene sulfonate was used as the electrolyte. Scanning electron microscopy (SEM) was used to determine the surface morphology of the films. The room-temperature conductivity values of the films were found to be in the range of 1.9-4.4 x 10(-4) (Omega cm)(-1), depending on the supporting electrolyte concentration. The temp...
Immobilization of Invertase in a Novel Proton Conducting Poly(vinylphosphonic acid) - poly(1-vinylimidazole) Network
Isikli, Suheda; Tuncagil, Sevinc; Bozkurt, Ayhan; Toppare, Levent Kamil (Informa UK Limited, 2010-01-01)
A novel proton conducting polymer blend was prepared by mixing poly(vinylphosphonic acid) (PVPA) with poly(1-vinylimidazole) (PVI) at various stoichiometric ratios via changing molar ratio of monomer repeating unit to achieve the highest protonation. The polymer network having the most suitable stoichiometric ratio for substantial proton conductivity was prepared and characterized by FT-IR spectroscopy and proton conductivity measurements. The network was used for immobilization of invertase and some import...
Conducting Polymer Composites of Multiwalled Carbon Nanotube Filled Doped Polyaniline
Yilmaz, Faris; Kucukyavuz, Zuhal (Wiley, 2009-01-15)
A multiwalled carbon nanotube (c-MWNT)/polyaniline (PANI) composite was synthesized by an in situ chemical oxidative polymerization process. With the carbon nanotube loading increased from 0 to 30 wt %,, the conductivity also increased and became weakly temperature-dependent. Fourier transform infrared spectroscopy studies showed that the synthesis by an in situ process led to effective site-selective interactions between the quinoid ring of the PANI and the multiwalled nanotubes, facilitating charge-transf...
