A conducting-electroactive polyaniline/magnetite (PAni/Fe304) nanocomposite was synthesized using anilinium dodecylbenzene sulfonate (S1) as a reactive surfactant. First, S1 allowed magnetite dispersion in the aqueous phase and second, S1 performed as the monomer of polyaniline emeraldine base salt. Electron microscopy suggested core-shell morphology based on S1 amphiphilic character; that is, ...

Polyaniline was used as hole injection material for polymer light emitting devices (PLED) spin coated from a water based polyaniline/polystyrenesulfonate (Pani/PSS) dispersion. Data presented here were based on red, yellow, green and blue light emitting polymers (LEP). Depending on the applied bias voltages the devices were studied by electrical impedance spectroscopy (EIS) in a wide frequency ...

practical applications of conducting polymers such as polyaniline as membranes are particulary limitedbecause of their poor mechanical properties. however by mixing polyaniline with some conventional insulatingpolymers such as nylon and preparation composite films through solvent casting or blending, it seems to be asuitable way in order to increase the mechanical properties of the conducting p...

A solid phase extraction sorbent based on polyaniline/graphene nanocomposite is presented. The structure and morphology of synthesized nanocomposite were investigated by Fourier transform infrared spectroscopy, field emission scanning electron microscopy, X-ray diffraction and thermal gravimetric analysis. The dispersive solid phase extraction was employed to the isolation and preconcentration ...

The research efforts over the course of the last three years have led to the observance of a melt transition in the electroactive polymer polyaniline (PANI) in its base form which may facilitate some degree of melt processability. Structural characterization of films and fibers utilizing unique optical methods developed at Georgia Tech. has resulted in a new understanding of the relationship be...

A label-free electrochemical DNA sensor was fabricated by deposition of polyaniline and pristine graphene nanosheet (P/G(ratios)) composites in different mass ratios, DNA probe and bovine serum albumin (BSA) layer by layer on the surface of a glassy carbon electrode (GCE). Electrochemical impedance spectroscopy (EIS) was employed to monitor every step of fabrication of P/G(ratio)-based DNA sens...
