Gas Separation Membranes - A simplified explanation of the abstract
This abstract first appeared for US patent application 18284147 titled 'Gas Separation Membranes
Simplified Explanation
The gas separation membrane described in the abstract consists of multiple layers, including a porous support layer, a discriminating layer with specific chemical groups, a fluorinated polymer layer, and optionally a protective layer. The discriminating layer contains metal or metalloid atoms and oxygen atoms in specific configurations.
- The gas separation membrane includes a porous support layer with low levels of monovalent metal ions.
- The discriminating layer contains groups with a specific chemical formula, including metal or metalloid atoms and oxygen atoms.
- The optional fluorinated polymer layer may be included in the membrane structure.
- The optional protective layer provides additional durability and protection to the membrane.
