A facile and simple approach to synthesis and characterization of methacrylated graphene oxide nanostructured polyaniline nanocomposites

Abstract

<jats:title>Abstract</jats:title><jats:p>A novel, scalable methacrylated graphene oxide (MeGO) nanostructured polyaniline (PANI) nanocomposite was synthesized and electrodeposited on the surface of fluorine-doped tin oxide electrode (FTOE). The two-dimensional support maintained a suitable substrate and arrayed in a conductive polymer matrix, creating an ultra-superconductive platform with extraordinary characteristics. The versatility of the nanocomposite performance was corroborated by altering the amount of MeGO coated on FTOE and changing the charge density of electro-polymerized PANI on the substrate. This exceptional nanostructure material enabled a robust platform design that demonstrated the extraordinary performance with enhanced conductivity and stability. Charge transfer resistance (<jats:italic>R<jats:sub>ct</jats:sub></jats:italic>) was dramatically decreased from 11,000 (for bare FTOE) to 65 (for MeGO/PANI).</jats:p>

A highly sensitive biosensor based on methacrylated graphene oxide-grafted polyaniline for ascorbic acid determination

“…Electropolymerization of PANI on the electrode surface was established according to our previous study [6]. Briefly, electrodepositing PANI on the MeGO-grafted FTO was initiated with 20 successive cyclic voltammograms (CVs) in a solution consisting of 0.03 M aniline monomer.…”

“…Biosensors have attracted much attention due to their unique properties such as simple procedure, easy production, fast response and cost efficiency [1][2][3]. Polyaniline (PANI) is a semi-flexible conducting polymer of the organic semiconductor family [4], which has attracted intensive interest as a result of remarkable features including superior conductivity [5], environmental stability [6], intriguing redox process [7] and inexpensive starting material [8]. In multidisciplinary areas, various applications for PANI have been reported such as biosensors, supercapacitors, biofuel cells, actuators, corrosion protection, membranes, solar cell devices, and rechargeable batteries [4,[9][10][11][12].…”

“…Also, graphene-grafted PANI nanocomposites are utilized for preparing the electrode substrates. Recently, graphenegrafted PANI nanocomposites with excellent electrochemical characteristics and great conductivity have been utilized for numerous purposes such as biosensors, energy storage tools and electrochemical devices [6].…”

“…Our group previously synthesized NFG/AgNPs/PANI for AA biosensing, which was more complex and expensive [52]. Moreover, we synthesized methacrylated graphene oxide (MeGO)/PANI nanocomposite and characterized it by physiochemical and electrochemical tests [6]. In this study, a simpler nanocomposite based on MeGO-grafted PANI is applied as electrochemical biosensor that has several benefits including cost efficiency, high sensitivity and good selectivity over AA determination.…”

Electrical conductivity of interphase zone in polymer nanocomposites by carbon nanotubes properties and interphase depth

“…Polymer nanocomposites encompassing conductive fillers such as carbon nanotubes (CNT) can support the requests in electronics, sensors, and shielding 1–23 . The nanocomposite's conductivity needs the conductive networks for charge conveyance established at or above the percolation onset.…”
