In-situ synthesis and characterization of conducting metal — polyaniline nanocomposites
Metal—Polyaniline nanocomposites such as Platinum-Polyaniline nanocomposite is prepared by insitu oxidative polymerization of aniline and reduction of Pt+4 ions into Pt nanoparticles. Thepolymerization of aniline was carried out in the presence of 1(2PtCN6 [Potassium Hexa CyanoPlatinate (IV)] as oxidizing agent. During the reaction aniline monomers undergo oxidation andform polyaniline (PANT) w...
متن کاملA mild, copper catalyzed route to conducting polyaniline.
The aniline dimer, N-(4-aminophenyl)aniline has been polymerized cleanly under mild conditions to obtain an emeraldine base form of polyaniline using [MeB(3-(Mes)Pz)3]CuCl as the catalyst and H2O2 as the oxidant, while the subsequent acidification of the emeraldine base gives the conducting emeraldine salt form of polyaniline.
متن کاملAdvanced Synthesis of Conductive Polyaniline Using Laccase as Biocatalyst
Polyaniline is a conductive polymer with distinctive optical and electrical properties. Its enzymatic synthesis is an environmentally friendly alternative to the use of harsh oxidants and extremely acidic conditions. 7D5L, a high-redox potential laccase developed in our lab, is the biocatalyst of choice for the synthesis of green polyaniline (emeraldine salt) due to its superior ability to oxid...

متن کاملSynthesis and Electrical Properties of Polyaniline Composite with Silver Nanoparticles
Polyaniline/silver (PANI/Ag) nanocomposite was prepared by chemical oxidative polymerization of aniline monomer in the presence of nitric acid. The formation of PANI/Ag nanocomposite was characterized by XRD, FTIR, TEM, UV-vis spectroscopy. The XRD patterns indicated that the crystalline phase of Ag is cubic with crystallite size of 93 nm. The TEM image shows that the Ag nanoparticles are well ...
