Although only a single layer of epitaxial graphene exists on SiC, the contact angle drastically changes from 69{\\deg} on SiC substrates to 92{\\deg} 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 and highly ordered pyrolytic graphite (HOPG). After graphene is treated with oxygen plasma, the level of damage is investigated by Raman spectroscopy and correlation between the level of disorder and wettability is reported.
