Graphical abstractA way to highly effectively produce graphene sheets with large lateral dimension in aqueous solution is demonstrated by combining electrochemical and ultrasonic methods. Electrical and mechanical properties of graphene film materials fabricated with these graphene sheets are largely improved. As well, polymer-graphene composites can be prepared conveniently both for water soluble polymers and for organic soluble polymers.Image 1

Graphical abstractIn this manuscript, the structures and electronic spectra of two ordered periodic grain boundaries (GBs), dual-parallel and zigzag-type GBs, on a graphene surface are studied using scanning tunneling microscopy and spectroscopy. Our results demonstrated that a GB consisting of triple anti-parallel periodic dislocation cores of pentagonal–heptagonal (5–7) carbon rings results in an enhanced localized state at 0.45 eV above the Dirac point on graphene surfaces, which is attributed to van Hove singularities (VHSs). Moreover, the energy positions of the localized states are varied between 0.40 and 0.47 eV depending on the site and eventually decayed to 0.36 eV. The variation of the energy positions is induced by two parallel GBs because of the higher electron density at the GB as a defect center and the lower electron away from the GB. Another periodic GB with a symmetric zigzag structural feature induced VHSs at –0.038 and 0.12 eV near the Fermi level. We believe that this contribution is theoretically and practically relevant because it is the first study of a triple antil-parallel GB in graphene, and the periodic GBs embedded in graphene are promising with regard to improving the performance of graphene-based electronic devices.
