Preparation of Metallocene-Containing Cationic Polymers for Anion Exchange Application


Reference #1283:

The University of South Carolina is offering licensing opportunities for the preparation of metallocene-containing cationic polymers for anion exchange applications.



Anion exchange membranes (AEMs) have attracted more interest in recent decades because anion exchange membrane fuel cells (AEMFCs) use less expensive metallic catalysts and provide higher energy efficiency compared to proton exchange membrane fuel cells (PEMFCs). However, most available anion exchange materials suffer from either poor mechanical property or long term alkaline stability. Our design provides concepts and synthetic routes for a family of hydrocarbon based polymers with novel metallocene cations. In addition, some polymers we studied showed largely improved mechanical and alkaline stability and have great potential for AEMFCs application.


Invention Description:

This invention in various aspects is directed to the synthesis of cationic metallocene-containing monomers and their polymers by various polymerization methods, as well as their potential application for anion-exchange membranes.


Potential Applications:

Fuel cells


Advantages and Benefits:

Novel design of metallocene-containing cationic polymers, accessible synthetic routes for monomers and various polymerization methods, good mechanical and alkaline stability, high conductivity.
