Electrochemical characteristics of graphene nanoribbon/polypyrrole composite prepared via oxidation polymerization in the presence of poly-(sodium 4-styrenesulfonate)

Graphene nanoribbon (GNR)/polypyrrole (PPy) composite is synthesized via in situ chemical oxidation polymerization in presence of poly-(sodium 4-styrenesulfonate) (PSS) as a surfactant. The morphology of GNR/PPy composites is observed by field emission scanning electron microscopy (FESEM) and transm...

Description
Summary:Graphene nanoribbon (GNR)/polypyrrole (PPy) composite is synthesized via in situ chemical oxidation polymerization in presence of poly-(sodium 4-styrenesulfonate) (PSS) as a surfactant. The morphology of GNR/PPy composites is observed by field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM). The electrochemical properties are characterized using galvanostatic charge–discharge and cycle voltammetry (CV). The specific capacitance of GNR/PPy composites shows the highest value of 881 F g−1 that in presence of 9 wt% GNR at a current density of 0.5 A g−1. The GNR/PPy composite also demonstrates the good cycle stability with only 16% decay of initial capacitance that much lower than 64% decay of pure PPy after 1000 cycles. [Display omitted] •PPy/GNR nanocomposites are synthesized using in situ chemical polymerization.•The notable specific capacitance of 881 F g−1 at a current density of 0.5 A g−1 is obtained.•Excellent cyclic stability of PPy/GNR nanocomposites is achieved.
