A template-free rapidly mixed reaction was employed to synthesize polyaniline nanofibers using chemical oxidative polymerization of aniline. Hydrochloric acid (HCl) and camphor sulfonic acid (CSA) were used in the synthesis to obtain 30and 50-nm average diameter polyaniline nanofibers. The nanofibers were deposited onto layered ZnO/64◦ YX LiNbO3 surface-acoustic-wave transducers. The sensors we...

The three-dimensional structures of emeraldine base polyaniline (PANI) and (polyaniline)(0.5)V(2)O(5) x 1.0 H(2)O have been determined by total X-ray scattering experiments. Atomic pair distribution functions (PDF) were measured to obtain experimental observables against which structural models were tested and refined. The PDF approach is necessary because of the limited structural coherence in...

This work reports a hard self-template method to synthesize core/shell like Fe3O4@C microparticles, in which the Pd nanocrystals can be alternatively incorporated into the carbon shells. The Fe3O4@polyaniline core/shell microspheres were first synthesized as the precursor by in situ polymerization of aniline onto the surface of the Fe3O4 microspheres. In a subsequent carbonization of the precur...

We present here an electrochemical sensor microsystem for the monitoring of pH. The all-polymeric device is comprised of a cyclic olefin copolymer substrate, a 200 nm-thin patterned layer of conductive polymer (PEDOT), and a 70 nm electropolymerized layer of a pH sensitive conductive polymer (polyaniline). The patterning of the fluidic (microfluidic channels) and conductive (wiring and electrod...

Froln broad-band temperature dependent transport studies on PAni-blends we can now conclude that the electric conductivity of PAni is governed by charge hopping on aInesoscopic scale between metallic crystalline regions (8 nm) separated by thin amorphous

unmodified zeolites show little affinity for anions due to the fact that their surfaces are negatively charged. however modification of zeolites with amines turns their negative surface charge to positive and creating higher adsorption capacity for anions. in this study, polyaniline-clinoptilolite composite was prepared by polymerization of anilinium on the surface of zeolite. the composite was...

ABSTRACT. Polyaniline-tin(IV)molybdophosphate composite exchanger was prepared using sol–gel method by mixing polyaniline gel into the inorganic precipitates of tin(IV)molybdophosphate. The ion characterized various techniques such as XRD, UV-Vis, FTIR, SEM-EDX, and PL. Photocatalytic activities antibacterial efficiencies bare polymer (PANI), tin(IV)molybdophosphate (TMP) polyaniline-tin(IV)mol...

CoFe2O4 Magnetic Nano Particles (MNPs) were synthesized by an efficient method in aqueous medium with the particle sizes of about 20-50 nm. Then, a hybrid nanocomposite of polyaniline (PANI)-CoFe2O4 MNPs has been electrodeposited directly on a stainless steel wire by the potentiostatic method. Microscopic images of electrodeposited PANI and PANI-C...
