The zeolite additive is constituted of internal holes/cages, suitable for encapsulating cations and molecules. Functionalities can be designed either by purposely filling these holes with appropriate active molecules/ions or the empty cages can be used to remove ions/molecules from the environment. These colorless, odorless, almost invisible additives can be delivered as sprays, surface coatings and can be incorporated into polymers and textiles with different form factors.
