Polyaniline salts are being prepared with the use of acids by the oxidation of aniline using ammonium persulfate. Aim of this work is to avoid the use of acids in the preparation of polyaniline salt, which is acidic in nature. The synthesis was carried out by the oxidation of ammonium persulfate in presence of alcohol, β-naphthol, without using any acids. This novel polyaniline salt contains dual dopants of β-naphthol and sulfuric acid. Sulfuric acid group was generated from ammonium persulfate during the oxidation of aniline. This synthesis proce dure gave nano sized fiber form of polyaniline salt having crystalline nature with optoelectronic and fluorescence property.
