Thin Film Polyaniline/Silver Nanowires Nanocomposites for Optoelectronic Applications

Abstract

In this work TE thin films based on the nanocomposite of AgNW and polymer polyaniline (PANI) were processed via spincoating during which various wt% of polymer dispersions were coated on a layer of AgNWs, after which the nanocomposite was doped with orto-phosphorous acid to transform the polymer from its non-conductive emeraldine base (EB) to its conductive state – emeraldine salt (ES). PANI/AgNWs nanocomposites have shown promising optoelectronic properties, where the best ratio of optical transparency and sheet resistance was obtainted with the composition of AgNW suspension 1:1 and PANI 0.5 wt%. The values of 84.6% and 35 Ω/□ achieved for transparency and sheet resistance respectfully, could be considered adequate for TE performance.
