(Chemical Equation Presented) Filling in: A new layered silicate material is prepared from a 3D porous silicate framework (AMH-3) by a novel procedure involving ion exchange and sequential intercalation. Layers of swollen AMH-3 are incorporated into a polymer, resulting in a mixed-matrix nanocomposite (see picture). The room-temperature hydrogen/carbon dioxide ideal selectivity of the swollen nanocomposite membranes is improved by a factor of two compared to the pure polymer.
