Thin layer chromatography plates and related methods

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. 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.

1. A method for manufacturing a thin layer chromatography plate, the method comprising:
forming a catalyst layer disposed on a substrate that includes a first portion and at least a second portion, each of the first and at least a second portions exhibiting a selected non-linear configuration; forming a layer of elongated nanostructures on the first and at least a second portions of the catalyst layer, wherein the layer of elongated nanostructures includes a first portion grown on the first portion of the catalyst layer and at least a second portion grown on the at least a second portion of the catalyst layer; at least partially coating the elongated nanostructures with a coating, the coating including at least one of a stationary phase or a precursor of a stationary phase for use in chromatography; after the act of at least partially coating the elongated nanostructures with a coating, at least partially removing the elongated nanostructures; and exposing the coating to an acid in order to bond hydroxyl groups to the coating.
