“…The conductivity measurements of the SF/PASA0, SF/PASA1, and SF/PASA2 scaffolds were carried out in wet state at room temperature using a conventional four‐point probe method (Agilent B2900A digital 4‐probe tester). The samples were compressed into disks at 3000 psi . The conductivity of the scaffolds in dry state was also tested.…”

Silk fibroin (SF) with good biocompatibility and degradability has great potential for tissue engineering. However, the SF based scaffolds lack the electroactivity to regulate the myogenic differentiation for the regeneration of muscle tissue, which is sensitive to electrical signal. Herein, a series of electroactive biodegradable scaffolds based on SF and water-soluble conductive poly(aniline-co-N-(4-sulfophenyl) aniline) (PASA) via a green method for skeletal muscle tissue engineering are designed. SF/PASA scaffolds are prepared by vortex of aqueous solution of SF and PASA under physiological condition. Murine-derived L929 fibroblast and C2C12 myoblast cells are used to evaluate cytotoxicity of SF/PASA scaffolds. Moreover, myogenic differentiation of C2C12 cells is investigated by analyzing the morphology of myotubes and related gene expression. These results suggest that electroactive SF/PASA scaffolds with a suitable microenvironment, which can enhance the myogenic differentiation of C2C12 cells, have a great potential for skeletal muscle regeneration.

“…The attempt was to prepare cellulose and conductive polymer as binary blend system. The example of in situ polymerization of cellulose and conductive polymer was successfully performed by using polyaniline (PAN) [63,64] and polypyrrole (PPy) [65,66]. In this process, in situ polymerization referred to a process that the monomer such as aniline and pyrrole are polymerized in the existence of cellulose and it was deposited on the surface of cellulose [67,68].…”

“…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].…”

Abstract. Reduced graphene oxide (rGO) was synthesized using sonication-assisted oxidation of graphite followed by reduction with ascorbic acid as environmentally friendly reductor. The polyaniline was prepared via chemical polimerization of aniline in 0℃. The rGO and polyaniline were blend in three mass compotitions of 1:3, 1:1, and 4:1 to produced rGO/polyaniline nanocomposites. The rGO/polyaniline nanocomposites were characterized using Raman spectroscopy, Fourier transform infrared spectroscopy and LCR meter. The rGO sheets as the support materials could provide more active sites for the nucleation of polyaniline, where polyaniline acts as conducting support. The rGO/polyaniline nanocomposites was deposited on synthetic graphite substrate laminated the glass substrate and applied as the counter electrode for efficient dye sensitized solar cells (DSSC). The rGO/polyaniline nanocomposite is an efficient counter electrode because of Pt/TCO free. The usage of rGO/polyaniline nanocomposites film as counter electrode in DSSC was demonstrated. The best performance was obtained for rGO/Polyaniline ratio of 4:1. Here, the optimum short circuit current density (Jsc), the open circuit current (Voc), the fill factor (FF), and the overall conversion efficiency under AM 1.5, 100 mW cm −2 illumination are 7.853 mA/cm 2 , 0.64 Volt, 47.2% and 2.64%, respectively.
