“…The significant decrease of Mott temperature in the ternary composite indicates a less disordered system, which is due to the presence of f-SWCNT/Au nanohybrid fillers in the sample. A similar decrease in Mott temperature due to introduction of Au nanoparticles into PANI has been observed previously by other researchers [23,25].…”

Abstract. Polyaniline (PANI) is the most important conducting polymer with excellent electrochemical properties. So PANIbased biosensors may find wide applications in medical diagnostics. We report here a ternary nanocomposite of gold nanoparticle-decorated single-walled carbon nanotubes (SWCNTs) embedded in sulfonated polyaniline matrix, prepared using a simple solvothermal chemical route. The structural and morphological characteristics have been determined by electron microscopy, X-ray diffraction and Raman spectroscopy. Optical characteristics of the nanocomposite have been determined by ultraviolet (UV)-visible absorption spectroscopy and photoluminescence spectroscopy. The direct current (DC)-conductivity measurement of the material shows a significant increase in electrical conductivity at 353 K from 7.80·10 -2 S/m for pure SPANI to 10.91 S/m for the 3-phase nanocomposite as synthesized in the present investigations. Thus the incorporation of SWCNT/Au nanohybrid fibers in the PANI matrix enhanced its electrical properties. Sulfonation increased the processability of the material, as the samples have now been found to be soluble in water and common organic solvents like DMSO. Such a functional nanocomposite will make an excellent biosensor electrode material.

“…The decrease in band gap with incorporation of SWCNT and SWCNT/Au hybrid is compatible with their better electrical conductivities [23]. The PL spectra for the different samples are obtained for an excitation wavelength of 300 nm and are shown in Figure 9.…”

“…In the domain of functional materials, PANI is also attractive as base matrix for many metal‐organic composites. Several metal‐PANI composites such as PANI/Pd,7 PANI/Pt,8 PANI/Au,9 PANI/Co,10 PANI/Cu,11 and PANI/Ag12 have been prepared. These composites display not only higher modulus, heat resistance, surface hardness, and conductivity but can also use for corrosion protection, electrocatalysis, biosensor, and hydrogen storage.…”

Polyaniline/silver (PANI/Ag) nanocomposite was successfully prepared by in‐situ polymerization from nanosilver sol using aniline (An) as both dispersant and stabilizer and characterized by FT‐IR, XRD SEM, TEM and electrochemical methods, respectively. The results showed that core‐shelled composite particles of less than 100 nm were synthesized with PANI as shell formed around a core of silver nanoparticles at higher aniline levels. Compared to pure PANI, PANI/Ag nanocomposites have higher electrical conductivity (65.98 S/cm) and current response and capacitance as well. Potentio dynamic polarization showed the anodic shifting of zero current potential and a lower exchange current density for the PANI/Ag composite. Compared with PANI, the PANI/Ag nanocomposite is a promising candidate for coatings with improved anti‐corrosion performance. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

“…Polyaniline as an electronically conductive polymer has attracted considerable attention. Because of its excellent environmental stability in the electro-conducting form, it has many potential applications; unique electrical and optical properties [31][32][33][34][35][36][37][38][39][40][41]. The applications of polyaniline have been limited due to its poor processability [42], which is true for most conducting polymers.…”
