Abstract
One or more techniques are disclosed for a method for functionalized a graphitic material comprising the steps of: 1) providing a graphitic material; 2) providing a first molecule comprising a first group, a spacer, and a second group; 3) providing a second molecule comprising a third group, a spacer, and a fourth group, wherein the third group is a different group from the first group; and 4) bonding the first molecule and the second molecule to the graphitic material. Also disclosed is a tunable material composition comprising the functionalized carbon nanotubes or functionalized graphene prepared by the methods described herein.
