Innovation Summary:
This invention provides a method for producing anion exchange membranes (AEMs) by chemically modifying polystyrene-block-polybutadiene-block-polystyrene (SBS) polymers. The process involves partial hydrogenation followed by epoxidation of the remaining double bonds, resulting in membranes with enhanced ionic conductivity and chemical stability. These AEMs are well-suited for use in electrochemical devices such as fuel cells and electrolyzers, offering a balance of performance, durability, and manufacturability.
Challenges / Opportunities:
Developing durable and efficient AEMs is critical for advancing clean energy technologies. Traditional membranes often suffer from poor chemical stability and limited conductivity, which restrict their long-term use in harsh electrochemical environments. This invention addresses these limitations through a novel polymer modification strategy, opening opportunities for more efficient and cost-effective electrochemical systems in energy and environmental applications.
Key Benefits / Advantages:
✔ Improved conductivity enhances ion transport efficiency
✔ Chemically stable in alkaline environments
✔ Scalable process suitable for industrial membrane production
✔ Versatile application across electrochemical technologies
