Abstract
AbstractA 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 (Rct) was dramatically decreased from 11,000 (for bare FTOE) to 65 (for MeGO/PANI).
Highlights
Since the industrialization of synthetic polymers, the polymers possessed sensitive attention in various applications [1, 2, 4,5,6,7,8,9,10,11]
To the best of our knowledge, the nanocomposite consisting of methacrylated graphene oxide (MeGO) and electropolymerized PANI was synthesized for the first time by a novel, simple and cost effective protocol, which can be applied in electrochemical biosensors, cardiac tissue engineering, biofuel cells and super-capacitors due to its extraordinarily high conductivity which can further increase sensitivity
For electro-deposition of PANI on FTO modified with MeGO, 20 successive cyclic voltammograms in a solution consisting of 0.03 M aniline monomer and 0.5 M H2SO4 were applied on the electrode surface
Summary
Since the industrialization of synthetic polymers, the polymers possessed sensitive attention in various applications [1, 2, 4,5,6,7,8,9,10,11]. Graphene-grafted PANI nanocomposites have been remarkably significant because of the excellent characteristics of 2D graphene nanosheets and good porosity of nanostructured PANI [40]. This strategy triggers outstanding sensitivity, improved conductivity, more selectivity and high capacity [41]. To the best of our knowledge, the nanocomposite consisting of MeGO and electropolymerized PANI was synthesized for the first time by a novel, simple and cost effective protocol, which can be applied in electrochemical biosensors, cardiac tissue engineering, biofuel cells and super-capacitors due to its extraordinarily high conductivity which can further increase sensitivity
