Synthesis of Uniform Polyaniline Nanofibers through Interfacial Polymerization

The present paper aims to study the preparation of polyaniline nanofibers through simple interfacial polymerization. Ammonium persulfate, hydrochloric acid and chloroform were used as oxidant, dopant and organic solvent respectively. Field Emission Scanning Electron Microscopy (FESEM), X-ray diffraction and Fourier Transform Infrared Spectroscopy (FTIR) techniques were used to analyze the produ...

Electrochemical Synthesis of Polyaniline Nanoparticles and Nanofibers

The electrochemical deposition of polyaniline nanofibers and nanoparticles have been investigated on gold electrodes by cyclic voltammetry and their morphology by high resolution scanning electron microscopy and atomic force microscopy. The type and dimensions of the nanostructures obtained depend on deposition conditions such as monomer concentration, scan rate and electrical potential. We hav...

Synthesis and Electrical Properties of Polyaniline/Polyaniline Grafted Multiwalled Carbon Nanotube Mixture via In Situ Static Interfacial Polymerization

The mixture of polyaniline (PANi) and PANi grafted multiwalled carbon nanotube (PANi-g-MWNT) was prepared by a two-step reaction sequence. MWNT was first functionalized with 4-aminobenzoic acid via ‘‘direct’’ Firedel-Crafts acylation in polyphosphoric acid (PPA)/phosphorous pentoxide (P2O5) medium to afford 4-aminobenzoyl-functionalized MWNT (AFMWNT). Then, aniline was polymerized via an in sit...

Transparent and conductive thin films of graphene/polyaniline nanocomposites prepared through interfacial polymerization.

This communication reports a simple, one-pot procedure for the synthesis and processing of transparent and conductive thin films of graphene/polyaniline nanocomposites based on an interfacial polymerization. Thin films presenting transmittance of 89% and sheet resistance of 60.6 Ω sq(-1) are spontaneously obtained and can be easily transferred to suitable substrates.
