Freestanding and flexible graphene/polyaniline composite paper was prepared by an in situ anodic electropolymerization of polyaniline film on graphene paper. This graphene-based composite paper electrode, consisting of graphene/polyaniline composite sheets as building blocks, shows a favorable tensile strength of 12.6 MPa and a stable large electrochemical capacitance (233 F g(-1) and 135 F cm(...

Oxidative polymerization of aniline in aqueous solution in the presence of trehalose was conducted. Fourier transform infrared spectroscopy confirmed successful preparation of polyaniline containing a trace amount of trehalose. Electron spin resonance spectroscopy revealed that electron spin concentration of the polyaniline increases with aniline/trehalose ratio in the polymerization. Scanning ...

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-cofe2o4 nanocomposite coatings were obtained by s...

We have prepared high surface area, conductive, mechanically robust, responsive polyaniline-carbon nanotune composite films. These were produced by filtration from dilute dispersions of polyaniline nanofibers and single-walled carbon nanotubes. Unlike polyaniline alone, these composites are mechanically stable, maintain large intractable surfaces and exhibit greatly enhanced response/recovery b...

Polyaniline-gold nanocomposites containing polyaniline nanostructures attached to well-dispersed uniform-size gold nanoparticles were obtained using a surface initiation approach.

Particles of Cobalt ferrite, CoFe2O4-, were coated with polyaniline (PANI) sulphate and phosphate during in-situ polymerization of aniline in an aqueous solution of sulfuric and phosphoric acid. The PANI-ferrite composites were characterized by Fourier transform infrared (FTIR) spectroscopy. Structures and morphology of products were studied by X-Ray Diffraction (XRD) and Scanning Electron Micr...

Polyaniline shows great potential and promises wide application in the biomedical field thanks to its intrinsic conductivity and material properties, which closely resemble natural tissues. Surface properties are crucial, as these predetermine any interaction with biological fluids, proteins and cells. An advantage of polyaniline is the simple modification of its surface, e.g., by using various...

The emergence of flexible and stretchable electronic components expands the range of applications of electronic devices. Flexible devices are ideally suited for electronic biointerfaces because of mechanically permissive structures that conform to curvilinear structures found in native tissue. Most electronic materials used in these applications exhibit elastic moduli on the order of 0.1-1 MPa....
