Abstract:
The evaporation processes of water from the edge region of graphene sheets was investigated by means of the direct molecular orbital-molecular dynamics (MO-MD) method at the AM1 level. Five graphenes with n = 1, 7, 19, 37, and 61 (where n is the number of benzene rings in the graphene) were examined as models of graphene sheets. The edge carbons of each graphene were terminated by hydrogen atoms. In the H2O-graphene interaction system, the oxygen atom of the water molecule binds to one or two C-H hydrogen atoms of the edge carbons. The binding energy of H2O increased gradually as a function of n and was saturated around n = 61. At low temperature (10-100 K), the water molecule was still connected to the graphene sheet, whereas the evaporation of H2O was found above 300 K. The mechanism of water evaporation is discussed on the basis of theoretical results. (C) 2010 The Japan Society of Applied Physics

Abstract:
Effects of water molecules on the electronic states of graphene have been investigated by means of density functional theory (DFT) and time-dependent DFT methods at the PW91PW91 and B3LYP/6-31G(d) levels of theory. Solvation caused by one to four water molecules (n = 1-4) was examined in the present study. A graphene composed of 14 benzene rings was used as a model of finite-sized graphene (C42H16). The water molecules interact with the graphene surface via hydrogen bonding. The band gap of graphene was slightly red-shifted by the solvation. This shift was caused by the formation of hydrogen bonds between H2O and the graphene surface. The electronic states of the graphene-water system were discussed on the basis of theoretical results.
