Electrochemical and Electrocatalytic Properties of Polyaniline Derivatives Membrane Modified Electrode

The fabrication of polyaniline-based membranes via thermally induced phase separation (TIPS) has been investigated using three PANI-diluent systems at three concentrations. The impact of the conditions of phase separation (including compositions, quenching temperature, and quenching time) on the membrane morphology, as determined by scanning electron microscopy and optical microscopy, was investigated. Variation of membrane morphology was attributed to different phase separation mechanisms. A bicontinuous lacy structure resulted from spinodal decomposition in the unstable region. On the contrary, a structure composed of aggregates of small particles was a consequence of nucleation and growth in the metastable region. The effect of coarsening (Ostwald ripening and coalescence) on the final membrane microstructure was also discussed.

A series of nanocomposites between aniline and vinyl acetate were synthesized chemically by an oxidative polymerization and inverse emulsion polymerization by using different solutions and oxidants such as ammonium persulfate/potassium iodate and potassium permanganate/benzoyl peroxide in the presence of various surfactants such as sodium dodecylbenzenesulfonate, poly(vinyl alcohol) and hydroxypropylcellulose, respectively. The products were characterized in terms of conductivity, morphology, particle size, conversion of monomers to polymer and molecular structure. The results show that the morphology, particle size and electrical conductivity of products are dependent on the type of surfactant and solution and the arrangement of monomer injection. The molecular structure of the product was studied by Fourier transform infrared spectroscopy.
