Abstract
Embodiments disclosed herein include graphitic stationary phase materials functionalized through a gas-phase functionalization reaction, as well as and methods for making and using these materials, including the use of these materials in separation technologies such as, but not limited to, chromatography and solid phase extraction. In an embodiment, a functionalized graphitic stationary phase material may be prepared from high surface area porous graphitic carbon and a radical forming volatilized functionalizing agent. The radical forming volatilized functionalizing agent produces an intermediate that forms a covalent bond with the surface of the porous graphitic material and imparts desired properties to the surface of the graphitic carbon.
