Empirical formula of graphane
WebTo study the elastic properties and deformations of graphane nano akes we apply the empirical method based on the bond-order potential developed by Brenner [ ]. e total energy is described by the sum of the bindingenergy ,thetorsionalenergytors,andthevander Waals energyvdW: tot= +tors+vdW. Webforces. Graphane has yet to be synthesized in pure bulk form. In order to facilitate the devising of improved syntheses of graphane, we here estimate the thermodynamic properties of graphane by semi-empirical methods. H f (CH, graphane) and S (CH, graphane) are estimated, respectively, as -8.8 ± 5 kJ mol-1 and 18 ± 4 J K-1 mol-1 at …
