Self-standing polyaniline film of mono-particle layer
چکیده انگلیسی

Large, uniform and stable polyaniline (PANI) films were fabricated by ordering and drying polyaniline-coated-polystyrene (PANI-PS) latex microspheres. Particles on a glass substrate were highly ordered, closely packed and formed a two-dimensional lattice structure with the thickness of the diameter of the particle, 3.2 μm. Films fabricated on the substrate were peeled off by the pressure of water to yield the floating film, which could be transferred onto other substrates. One end of the film was connected to the platinum plate electrode while the other end was put in sulfuric acid. The film to which voltage was applied showed color change corresponding to the redox reaction. The voltammogram of the film showed the cathodic and the anodic peaks at 0.20 and 0.35 V versus SCE, respectively, being similar to peaks of electropolymerized PANI films. Films were inserted into tetrahydrofuran to remove the core-polystyrene. The resulting film had similar properties as polyaniline films of PANI-PS latex microspheres.
