“…Another way to increase the miscibility and to obtain more uniform dispersion is to use water-soluble poly (styrene sulfonic acid)-graft-polyaniline [31,32] or polyaniline grafted onto graphene [33][34][35]. In this research we report the synthesis, characterization and electrochemical performances of new water-dispersable nanocomposites based on reduced graphene oxide (r-GO) and water-soluble poly(aniline-N-propanesulfonic) acid (PAnS).…”

Abstract. Three water-dispersable composites have been synthesized by in situ chemical oxidative polymerization of aniline N-propanesulfonic acid (AnS) in reduced graphene oxide (r-GO) dispersion, in an ice bath at 0°C and in the absence of any surfactant. The mass ratio between r-GO and aniline monomer have been established as (m r-GO :m AnS ) = 1:1, 1:2 and 1:5 while in the composites, the mass ratio between r-GO and polyaniline was found: 1:0.3, 1:0.5 and 1:1, respectively. The molecular structure, morphology, and optical properties of the composites were analyzed through Fourier transform infrared (FTIR), Raman and ultraviolet-visible (UV-Vis) spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM). Electrochemical performances for energy storage were evaluated by cyclic voltammetry and galvanostatic charge/discharge measurements with 1M H 2 SO 4 as electrolyte in a three-electrode cell. The composite with the mass ratio (m r-GO :m PAnS ) = 1:1 has showed good capacitive behavior with a specific capacitance of 1019 F/g at scan rate of 1 mV/s calculated from integrated area of cyclic voltammogram curve and a retention life of 80% after 100 cycles. These results indicate that the composites prepared by chemical oxidative polymerization are promising materials for electrode supercapacitors.

Summary: Conductive nanotubes were fabricated by the alternate adsorption of negatively charged polypyrrole (PPy) and positively charged poly(allylamine hydrochloride) (PAH) onto the inner pores of polycarbonate templates. Nanotubes are obtained by the subsequently removal of the template. Using several microscopic and spectroscopic techniques, we demonstrate that the yielded materials possess a tubular structure and conductive properties. The conductivity of PPy/PAH nanotubes is measured as 0.008 S · cm−1.SEM image of eight bilayer PPy/PAH nanotubes after the removal of the template.imageSEM image of eight bilayer PPy/PAH nanotubes after the removal of the template.

Conductive polymers (CPs) are an emerging technology in the field of biomaterials. While CPs retain a predominantly investigative role in the field of medical implants, they have shown potential across a wide range of applications, including neural interfaces, biosensors, nerve grafts, and drug-delivery devices.CPs have been extensively explored for addressing the limitations of conventional neuroprosthetic implant devices which employ metallic electrodes to interface with neural tissue. In this application CPs have the potential to provide a conductive interface with properties more suited to soft-tissue integration. Unlike conventional conductive materials CPs are relatively soft, with a textured surface conducive to cell attachment. The high surface area relative to the geometric base area means these materials also have good charge-transfer properties, with low impedance and negligible bilayer capacitance, a substantial limitation of existing neural-stimulation electrode technologies. These types of properties have resulted in much investigation of conductive polymers for a range of other medical applications, including biosensors, nerve regeneration templates, and for drug-delivery applications.
