Graphene/Polyaniline Nanofiber Composites as Supercapacitor Electrodes
TL;DR: In this paper, chemically modified graphene and polyaniline (PANI) nanofiber composites were prepared by in situ polymerization of aniline monomer in the presence of graphene oxide under acid conditions.

TL;DR: A method of synthesizing a hexagonal boron nitride (h-BN) thin film by ambient pressure chemical vapor deposition on polycrystalline Ni films is demonstrated and the potential usage of this h-BN film in optoelectronic devices is suggested.
Journal ArticleDOI
Graphene/nanosized silicon composites for lithium battery anodes with improved cycling stability
TL;DR: In this paper, two types of graphene samples were used and their composites with nanosized silicon were prepared in different ways and the presence of graphene in the composites has been proved to effectively enhance the cycling stability of silicon anode in the lithium-ion batteries.
Journal ArticleDOI
Graphene oxide/ferric hydroxide composites for efficient arsenate removal from drinking water.
TL;DR: A series of novel composites based on graphene oxide (GO) cross-linked with ferric hydroxide was developed for effective removal of arsenate from contaminated drinking water, and the efficiency of arsenates removal was decreased when pH was increased to higher than 8.
Journal ArticleDOI
Surfactant-intercalated, chemically reduced graphene oxide for high performance supercapacitor electrodes
TL;DR: In this paper, a series of surfactant-stabilized graphene materials were prepared by intercalation of graphene oxide (GO) with different surfactants, tetrabutylammonium hydroxide (TBAOH), cetyltrimethylammoniam bromide (CTAB), and sodium dodecylbenzene sulfonate (SDBS), followed by reduction using hydrazine.
