The rose leaf/polypyrrole (RL/PPy) composites were characterized in terms of morphology, chemical structure, and conductivity properties. The spectrum were obtained from FTIR results whi...

Recently, electronically conductive polymers have been studied as the subject of numerous investigations [1-2]. Among the conductive polymers, which have aromatic ring and heteroatom in the backbone, polypyrrole (PPy) [3] have been of particular interest due to its high electrical conductivity, environmental stability and interesting redox properti...

The electrochemical copolymerization of pyrrole (Py) and 1-dimethylaminopyrrole (DMAPy) was successfully carried out in the presence of three different types of surfactant (anionic, cationic and non-ionic) by cyclic voltammetric method. The influence of anionic (sodium dodecylbenzenesulfonate) (NaDBS), cationic (tetradecyltrimethylammonium bromide)...

Characteristics of nanocomposite films synthesized and deposited by atmospheric pressure Radio-Frequency (RF) (13.56 MHz) uniform glow discharge are examined. The nanocomposite thin film deposition is carried out in the presence of titanium dioxide (TiO2) with polymerization of pyrrole, thiophene and furan monomers in acetonitrile medium containing...

A new series of pyrrole family, N-substituted phenyl attached alkyl at the ortho, meta and para position were synthesized by a straight forward method and were exploited as an innovative monomer for electroactive polymers. Ionic liquids were employed as a medium for electro-polymerization of these monomers to obtain N-(methyl)phenyl polypyrroles. N...

Synthesis and chemical oxidative polymerization of some N-substituted pyrroles ((N-Py)s) were carried out using Clauson-Kaas method and FeCl3 in CHCl3 medium, respectively. The produced polymers, N-(p-benzoic acid)polypyrrole (NpbPPy); N-(o-aminophenyl)polypyrrole (NoaPPy); N-(m-nitrophenyl) polypyrrole (NmnPPy), were characterized by Fourier trans...

A series of alternating phylene and symmetrically bithiophene containing repeat units and the respective homopolymers have been synthesized and characterized by combining FTIR, UV-Vis spectroscopy, four probe conductivity measurement, TGA and SEM analysis. Quantum mechanical calculations of the structures and infrared spectra of the monomers and re...

Polypyrrole (PPy) was doped with the azocalix[4]arene [(5,11,17,23-tetrakis[(p-carboxyphenyl)azo]25,26,27,28-tetrahydroxycalix[4]arene)] host species. PPy/azocalix[4]arene salts were characterized by FTIR, TGA, SEM, X-ray diffraction, and conductivity measurements.
