这种差异性可能来源于以下几种原因之一:(1)与机械剥离的石墨烯不同,化学气相沉积法(CVD)制备的石墨烯通常具有原子尺度的缺陷,促进了质子的渗透(见图1A);(2)水溶液或质子导体中的石墨烯通过化学吸附质子发生氢化作用(见图1B),使六元环...
Here, we study the influence of commonly used etching solvents during the transfer process, i.e. ammonium persulfate, ferric chloride, and ferric nitrate, on the properties of CVD graphene by Raman spectroscopy. Obvious blue shift and broadening of Raman G and 2D peaks were observed for ...

Italy By combining scanning probe microscopy with Raman and x-ray photoelectron spectroscopies, we investigate the evolution of CVD-grown graphene/Ge(001) as a function of the deposition temperature in close proximity to the Ge melting point, highlighting an abrupt change of the graphene’s quality...
graphene wrinklessite‐selective passivationwater impermeabilityIn article number 1800022, Jinsung Kwak, Soon‐Yong Kwon, and co‐workers demonstrate that water‐permeable routes concentrated on graphene wrinkles are predominantly induced by the delamination of graphene on Cu during the cooling stage, ...
Gas-phase chemistry for the chemical vapour deposition (CVD) of metal precursors has been the subjects of theoretical investigations as gas-phase reactions, in particular, are found to play a key role in CVD process which has a number of important industrial and commercial applications. Theoretical...
1. Firstly, CVD monolayer graphene grown on a copper substrate was coated with poly(methyl methacrylate) (PMMA) film. The copper substrate was then etched completely using saturated K2S2O8 solution and HCl-H2O2-H2O (1:1:20) sequentially for 12 h. The resulting PMMA/MLG block was washed ...
The use of graphene in a form of discontinuous flakes in polymer composites limits the full exploitation of the unique properties of graphene, thus requiring high filler loadings for achieving- for example- satisfactory electrical and mechanical properties. Herein centimetre-scale CVD graphene/polymer na...
