(a) The measured water contact angle (WCA) and the calculated surface energy as a function of aging time on the graphene nanoshets after plasma treatment for 10 s. (b) Friction force as a function of normal force on graphene nanosheets with different aging time. B and A are the abbreviation of before and after respectively. PLA represents plasma treatment. PLA-10 means the time of plasma treatment is 10 s. A-2, A-4, A-6 and A-8 represent the aging time after plasma treatment are 2 h, 4 h, 6 h and 8 h respectively. The values of the WCA and the surface energy are concluded in Table S3.
