Surface-Energy Engineering of Graphene [PDF]

open access: yesLangmuir, 2010
Contact angle goniometry is conducted for epitaxial graphene on SiC. Although only a single layer of epitaxial graphene exists on SiC, the contact angle drastically changes from 69° on SiC substrates to 92° with graphene. It is found that there is no thickness dependence of the contact angle from the measurements of single, bi, and multi layer graphene
