View the Complete Application at the US Patent & Trademark Office
With an amino acid as a buffer, a method is disclosed for producing a proton-exchanged three-dimensional layered silicate material. Additional embodiments include a method for producing a swollen proton-exchanged three-dimensional layered silicate material. This new material is a result of reactive swelling which accompanies one or more major changes of the layer structure. The materials can be further processed such as with exfoliation. The materials may be combined with polymers to produce film membranes such as thin film porous membranes. The membranes are useful in separating gases and as absorbents.
