“…Indeed, the presence of the non-conductive paraffin oil at the electrode surface decrease the active surface area and then the electron transfer [47]. However, the electrical properties of CPE were improved after its modification by the functionalized CNFs, inducting their role to promote the electron transfer as reported previously using CNFs and other CNMs [11,12,46,48]. In the case of PPy film modified CPE and CNFs/CPE, the Rct value decreased even more compared to these electrodes before their modification.…”

“…Another nanocomposite of P-1,5-DAN and reduced graphene oxide (rGO) modified platinum patterned electrode was fabricated and used for Pb 2+ determination. The detection limit of Pb 2+ using the P-1,5-DAN/rGO/Pt was equal to 0.2 µg L -1 [12]. PPy and carbonaceous nanospheres (CNSs) modified screen-printed electrode (SPE) was also fabricated for a selective detection of Hg 2+ and Pb 2+ using SWASV [13].…”

In this paper, a new nanocomposite of polypyrrole (PPy) and carbon nanofibers (CNFs) modified carbon paste electrode (CPE) has been reported for the determination of traces lead ions (Pb 2+ ). The obtained nanocomposite was fabricated by combining the unique advantages of PPy and CNFs using a very simple approach, which consists on modifying the CPE by the functionalized CNFs and then by the PPy film using galvanostatic mode. Several techniques were used to investigate the functionalized CNFs and the PPy/CNFs nanocomposite including Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) for surface layers of CNFs, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) for the electrical proprieties of the PPy/CNFs nanocomposite. The surface morphologies were examined by field emission gun scanning electron microscopy (FEG-SEM). The square wave anodic striping voltammetry (SWASV) was used to investigate the analytical performances of the designed electrode PPy/CNFs/CPE. Different parameters that affect the stripping analysis of Pb 2+ including supporting electrolyte, deposition potential, and deposition time were investigated. Under the optimum experimental conditions, a good linearity between the stripping peak currents and the concentration of Pb 2+ was obtained in the range of concentration from 0.2 to 130 µg L -1 Pb 2+ . The detection limit was estimated to be 0.05 µg L -1 Pb 2+ . Finally, the proposed method has been successfully applied for the determination of Pb 2+ in real samples of tap water with satisfactory results.

Recent progress in nanocomposites based on conducting polymer: application as electrochemical sensors

Over the years, intensive research works have been devoted to conducting polymers due to their potential application in many fields such as fuel cell, sensors, and capacitors. To improve the properties of these compounds, several new approaches have been developed which consist in combining conducting polymers and nanoparticles. Then, this review intends to give a clear overview on nanocomposites based on conducting polymers, synthesis, characterization, and their application as electrochemical sensors. For this, the paper is divided into two parts: the first part will highlight the nanocomposites synthesized by combination of carbon nanomaterials (CNMs) and conducting polymers. The preparation of polymer/CNMs such as graphene and carbon nanotube modified electrode is presented coupled with relevant applications. The second part consists of a review of nanocomposites synthesized by combination of metal nanoparticles and conducting polymers.

“…Graphene electrodes currently can be divided into 3 types: pristine graphene, chemical vapor deposition (CVD) graphene and composite graphene electrodes, in which graphene/polymer composite material is most noticeable due to significant advantages of easy processing and low cost [6]. Graphene/polymer composite thin film electrodes have many important applications and they are usually synthesized by solution method using spin-coating, drop casting, Langmuir-Blodgett (LB), self-assembly techniques [6,7]. In recent years, 3D printing technology has strongly developed that makes the fabrication of thin film electrode much more easy, more precise and more rapid [8][9][10].…”

Graphene/polymer composite thin film electrodes have many important applications, but the fabrication of these electrodes is often difficult because of poor processability of graphene. This paper presents the primary results on using 3D printing technique for thin film electrode preparation from graphene-based composite ink. The printing ink was synthesized from graphene oxide (GO), polyvinyl alcohol (PVA) as a binder and stabilizer, and ascorbic acid (AA) as a reducing agent. The measured zeta potential value showed that PVA can make GO ink more stable, the absolute value of zeta potential increased from 10.1 mV (without PVA) to 31.4 mV (with 12 wt. % PVA). The thin film electrodes can be easily printed using GO/PVA/AA composite ink, and obtained voltammograms recorded on the surface of these electrodes in 5 mM K3[Fe(CN)6]/K4[Fe(CN)6] solution clearly indicated the GO reduction by AA. The best electrochemical properties of printed electrodes were founded in the case of composite ink with wt/wt ratio GO:PVA:AA = 80:12:8. The cyclic voltammetric results demonstrated the linear dependence of the anodic and cathodic signals of redox couple [Fe(CN)6]4-/K3[Fe(CN)6]3- with the square root of scan rate, indicating a reversible redox reaction on the electrode surface. The thin films printed from GO/PVA/AA composite ink can be used as electrode material for diverse applications in electrochemistry.
