Conducting composite films of Poly(N-vinylimidazole) with Polypyrrole were prepared electrochemically. Composites having different polypyrrole percentages showed conductivites in the range 10(-3)-10(-1) S.cm(-1) Characterization of composites was carried out with FTIR and scanning electron microscopy techniques. Temperature dependence of conductivities exhibited reversible behaviour and confirmed the variable range hopping theory.

Synthesis and characterization of conducting polypyrrole-cis-1,4-polybutadiene composites Yildirim, P; Kucukyavuz, Z (1998-05-30) Conducting composite films of cis-1,4-polybutadiene with polypyrrole were prepared electrochemically. Polymerization of pyrrole was carried on cis-1,4-polybutadiene-coated platinum electrodes. The composites having different polypyrrole percentages showed conductivity in the range 10(-1)-10(-6) S/cm. Conductivity measurements were done by using the standard four-probe technique. Characterization of the samples was carried out by FT-IR, scanning electron microscopy (SEM) and energy-dispersive X-ray (EDX) tec...
Preparation and characterization of conducting polybutadiene/polythiophene composites Kiralp, S; Kucukyavuz, Z; Qasrawi, AF (2003-01-01) Conductive composite films of cis-1,4-polybutadiene (PBD) with polythiophene, (PTh) were prepared electrochemicallly. Thiophene was polymerized on PBD-coated platinium electrodes. The composites with different PTh percentages showed conductivity in the order of 10(-3) (Omega cm)(-1). The characterization of the films was performed using FTIR, scanning electron microscope and differential scanning calorimetry techniques. In order to understand the dominant transport mechanism, the temperature dependence of c...
Synthesis of a hexafluoropropylidene-bis(phthalic anhydride)-based polyimide and its conducting polymer composites with polypyrrole Selampinar, F; Akbulut, Ural; Yilmaz, T; Gungor, A; Toppare, Levent Kamil (Wiley, 1997-10-01) A new electrically conducting composite film from polypyrrole and 4,4'-(hexafluoroisopropylidene)-bis(phthalic anhydride)-based polyimide was prepared. Pyrrole and the dopant ion can easily penetrate through the polyimide substrate and electropolymerize on the platinum (Pt) electrode due to the swelling of the polyimide on the metal electrode. The electrochemical properties of polypyrrole-polyimide (PPy/PI) composite films have been investigated by using cyclic voltammetry. The PPy/PI composite film is suit...
Processing and characterization of multilayer films of poly(ethylene terephthalate) and surface-modified poly(tetrafluoroethylene) Bayram, Göknur (2007-06-01) Multilayer films were prepared from poly(tetrafluoroethylene) (PTFE) and poly(ethylene terephthalate) (PET) films together with using an adhesion promoting layer (tie-layer) consisting of ethylene-methyl acrylate-glycidyl methacrylate (E-MA-GMA) terpolymer and low density polyethylene (LDPE) blend. Na/naphthalene treatment and subsequent acrylic acid grafting were applied on the surfaces of PTFE for chemical modification. FT-IR spectroscopy, XPS analysis and surface energy measurements were performed to cha...
A conducting composite of polythiophene: Synthesis and characterization Vatansever, Fatma; Hacaloğlu, Jale; Akbulut, Ural; Toppare, Levent Kamil (1996-01-01) Conducting polymer composites of polythiophene, using a polyamide as the insulating matrix, were prepared via electrochemical methods. The characterization of the composite was done by scanning electron microscopy, differential scanning calorimetry, thermogravimetric analysis, Fourier transform infrared and pyrolysis studies. The conductivities were measured by a four-probe technique. The cited methods revealed that the composites have properties different from those of simple mechanical mixtures of the two...
