Abstract
A method of forming a medium for gas adsorption includes providing a medium substrate with a de-functionalized hygroscopic layer, covering at least a portion of the medium substrate with a solution of an amine and a solvent, and removing excess solution from the medium substrate by evaporation to leave a coating of the amine on the substrate.

A method of forming a medium for gas adsorption, the method comprising:
- providing a medium substrate with a de-functionalized hygroscopic layer;
- covering at least a portion of the medium substrate with a solution of an amine and a solvent;
- and
- removing excess solution from the medium substrate by evaporation to leave a coating of the amine on the substrate,
- wherein a resulting surface on the substrate is hydrophobic.

A method of converting a medium designed for adsorption of a first gas into a medium designed for adsorption of a second gas different from the first gas, the method comprising:
- providing a medium substrate having a substance capable of adsorption of the first gas;
- covering at least a portion of the medium substrate with a solution of an amine and a solvent, the amine being capable of adsorption of the second gas;
- and
- removing excess solution from the medium substrate by evaporation to leave a coating of the amine on the substrate,
- wherein a resulting surface on the substrate is hydrophobic.
