Thermal analysis of conductive blends of PVDF and poly(o-methoxyaniline)
(2000-11-01)
The thermal behavior of blends of poly(vinylidene fluoride), or PVDF, and poly(o-methoxyaniline) doped with toluene sulfonic acid was studied by thermogravimetic analysis, electrical conductivity measurements, differential ...
Effect of chemical modifications on the electronic structure of poly(3-hexylthiophene)
(2013-05-15)
The widespread use of poly(3-hexylthiophene) (P3HT) in the active layers of organic solar cells indicates that it possesses chemical stability and solubility suitable for such an application. However, it would be desirable ...
Polaronic ferromagnetism in conducting polymers
(2001-12-01)
Ferromagnetic behavior at room temperature is reported in metal-free-conducting polymer samples of poly(3-methylthiophene) doped with ClO 4 -. Magnetic moments associated with spin 1/2 positive polarons are possibly ...
Simultaneous observation of the magnetic and electric behavior in a correlated system near a metal-semiconductor transition: ESR in pellets of conducting polymers
(Amer Physical Soc, 2009-07-01)
Electron spin resonance (ESR) experiments show, at the metal-semiconductor transition temperature of a conducting polymer, the distinct contributions of the disordered and crystalline regions. In the more disordered regions ...
Preparation and characterization of castor oil-based polyurethane/poly(o- methoxyaniline) blend film
(2007-07-15)
Blends made up of castor oil-based polyurethane (PU) and poly(o-methoxyaniline) (POMA) were obtained in the form of films by casting and characterized by FTIR, UV-Vis-NIR spectroscopy, and electrical conductivity measurements. ...

Dielectric relaxation and dc conductivity on the PVOH-CF(3)COONH(4) polymer system
(Springer Heidelberg, 2009-10-01)
In the present paper, the ionic conductivity and the dielectric relaxation properties on the poly(vinyl alcohol)-CF(3)COONH(4) polymer system have been investigated by means of impedance spectroscopy measurements over wide ...
Lithium ion motion in a hybrid polymer: Confirmation of a decoupled polyelectrolyte
(Wiley-Blackwell, 2007-08-24)
Electric and magnetic properties of polymer electrolyte/carbon black composites
(1998-12-01)
Measurements of 1H Nuclear Magnetic Resonance (NMR) relaxation times, Electron Paramagnetic Resonance (EPR) and AC Impedance Spectroscopy (IS) are reported for composites based on PEO8:LiClO4 and carbon black (CB), prepared ...
Effect of ion concentration of ionomer in electron injection layer of polymer light-emitting devices
(Elsevier B.V., 2006-06-15)
Polymer light-emitting devices (PLEDs) with poly(2-methoxy-5-hexyloxy)-p-phenylenevinylene (OC1OC6-PPV) as the emissive layer were studied with an electron injection layer of ionomers consisting of copolymers of styrene ...
