摘要:
In an embodiment, a method for manufacturing a thin layer chromatography (“TLC”) plate is disclosed. The method includes forming a layer of elongated nanostructures (e.g., carbon nanotubes), and at least partially coating the elongated nanostructures with a coating. The coating includes a stationary phase and/or precursor of a stationary phase for use in chromatography. Embodiments for TLC plates and related methods are also disclosed.

The coating includes a stationary phase and/or precursor of a stationary phase for use in chromatography. The stationary phase may be functionalized with hydroxyl groups by exposure to acidified water vapor or immersion in a concentrated acid bath (e.g., HCl and methanol). At least a portion of the elongated nanostructures may be removed after being coated. Embodiments for TLC plates and related methods are also disclosed.

Embodiments disclosed herein include functionalized graphitic stationary phase materials 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 manufactured from high surface area porous graphitic carbon and a radical forming functionalizing agent. The radical forming 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.

A method for forming a polymer on a substrate is disclosed. The method may include providing a substrate having a substrate surface, the substrate surface being at least partially hydrogen-terminated and reacting the substrate surface in a solution comprising at least one radical initiator and at least one monomer to form a polymer on the substrate surface. The monomer may comprise at least one of a monofunctional monomer and a polyfunctional monomer. A stationary phase for use in separation applications such as chromatography and solid-phase extraction is also disclosed. The stationary phase may include a plurality of diamond bodies and a polymeric compound covalently bonded to at least a surface portion of the plurality of diamond particles.
