Abstract: This invention discloses a composition of, a method of making, and an application of high plasticization-resistant chemically cross-linked organic-inorganic hybrid membranes such as cross-linked cellulose acetate-cellulose triacetate-polyurethanepropylsilsesquioxane membranes. These cross-linked membranes with covalently interpolymer-chain-connected hybrid networks were prepared via a sol-gel condensation polymerization of cross-linkable organic polymer-organosilicon alkoxide precursor membrane materials.

Abstract: A hydrogen separation membrane and its associated method of fabrication. The hydrogen separation membrane has a first material layer that is permeable to atomic hydrogen. The first material has a first catalytic ability to disassociate molecular hydrogen into atomic hydrogen. Complex particles are applied to the first material layer, either to produce a second layer or to act as a barrier between the first layer and a subsequent layer. The complex particles are hollow bucky structure, filled bucky structures or core particles coated with a hydrogen permeable metal. The complex particles prevent material from opposite sides of the hydrogen separation membrane from interdiffusing over time. Consequently, palladium based materials and Group V based materials can be used on opposite sides of the hydrogen separation membrane. This produces a hydrogen separation membrane that is more permeable to hydrogen in one direction than it is in the opposite direction.
