Synthesis of expanded graphite filled polyaniline composites and evaluation of their electrical and electrochemical properties

Characterization of an hrp-aox-polyaniline-graphite composite biosensor

“…The pure graphite sample decomposes above 600 °C, whereas the 20 % graphite composite presents four degradation steps (three attributed to the pure polyaniline and one to the pure graphite). Similar results were found by Kowner, et al [29], Bourdo, et al [30] and Mo, et al [31].…”

Reduced Graphene Oxide/Polyaniline Nanocomposite as Efficient Counter Electrode for Dye Sensitized Solar Cells

“…A CE material in DSSC should possess a high catalytic activity and stability toward electrolyte. Platinum (Pt) is the most preferred material for CE in DSSC, due to its excellent physical and chemical properties, such as a high electrical and thermal conductivity, catalytic activity toward I3 -, and corrosion resistance to iodide ions present in redox electrolyte [3][4][5]. However, because Pt is precious metal, it is high cost and prevented it from being widely used in commercial DSSC.…”

“…However, because Pt is precious metal, it is high cost and prevented it from being widely used in commercial DSSC. Recently, Pt-free materials with lower cost and good stability have been investigated as counter electrode for DSSC, mainly based on combination carbon materials and conducting polymers [1,[4][5][6]. Graphene, one of the allotropes of abundantly carbon is one of the most promising materials for application in solar cells.…”

“…Graphene, one of the allotropes of abundantly carbon is one of the most promising materials for application in solar cells. Graphene is possessing high conductivity, great mechanical strength, high carrier mobility, high specific area, and high optical transparency [1][2][4][5][6]. However, graphene is not perfect candidate for a counter electrode in DSSC, because it has limited number of active sites for I3 -/I -electro catalysis.…”

“…Polyaniline is a conducting polymer and has high catalytic activity which has been employed as the counter electrode for DSSC. The combination of graphene and polyaniline are believed as an efficient route [1][2][3][4][5][6]. The graphene /polyaniline nanocomposite was synthesized using insitu polymerization and deposited on fluorine-doped tin oxide glass has conversion energy efficiency reached 6.09% which is comparable to 6.88% of the cell with Pt counter electrode [2].…”
