Synthesis and characterization of nanostructured polythiophene in aqueous medium by soft-template method

Polythiophene is a standout amongst the most valuable sorts of the conducting polymers that hold numerous odd physical and electrical lands for instance dissolvability، electrical conductivity and develop the ecologically and thermally stable materials. Distinctive assembling techniques have been advanced for conducting polymer nanostructures and near them، template method is a facile and encouraging method. Nanostructured polythiophene was prepared by soft-template method in the vicinity of sodium dodecyl sulfate (SDS) as an anionic surfactant، triethanolamine (TEA) as a co-surfactant and ammonium persulfate (APS) as an oxidant in aqueous medium. Moreover، the chemical structure of fabricated nanostructured polythiophene was investigated by fourier transform infrared (FTIR) spectroscopy. The morphology and particle size of the product was studied by scanning electron microscope (SEM) and atomic force microscope (AFM). Furthermore، dispersion state of nanostructured polythiophene in organic solvents was studied after being dried. The results indicate that nano-product has a favorable fiber-like-structure with a diameter in the range of 85–100 nm.
