Plasticization-resistant crosslinked polymer membranes for
This technology involves specially engineered polymer membranes that can selectively separate different gases from each other—for example, pulling carbon dioxide out of a gas stream or separating oxygen from nitrogen. The polymers are chemically crosslinked, meaning their molecular chains are bonded together in a network that improves durability and prevents the membrane from swelling or degrading in harsh conditions. A key feature is that the crosslinking is triggered by ultraviolet light, which simplifies manufacturing compared to high-heat or chemical curing methods. The base polymer class—polyarylene ethers—is known for good gas permeability and selectivity, and the crosslinking is designed to enhance long-term performance stability.
What you could build
A membrane module product for industrial gas separation—such as CO2 capture from natural gas or flue gas, or hydrogen purification—sold to energy companies, chemical processors, or industrial gas suppliers who need durable, high-throughput separation systems.
Who in Virginia should care
Virginia-based energy and chemical processing companies, as well as defense contractors interested in gas purification for life support or fuel cell systems, would be plausible licensees or development partners.
Readiness: Lab validated
Concept — described but not yet demonstrated. Lab validated — supported by experimental results in the patent. Prototype likely — the text describes a built, working embodiment.
Readiness is inferred from the patent text, not from a lab visit.
