Prof. Licheng Sun’s group has published a groundbreaking study in Angewandte Chemie International Edition. The work introduces a novel Poly(arylmethylpiperidinium) (PAMP) anion exchange membrane (AEM) engineered with a unique pendant structure.
Prof. Licheng Sun’s group from Center for Artificial Photosynthesis and Solar Fuels at Westlake University recently published a research paper in the Angewandte Chemie International Edition. The paper is titled “Polyarylmethylpiperidinium (PAMP) for Next Generation Anion Exchange Membranes.”
By positioning the piperidinium cations away from the polymer backbone, this design effectively suppresses the Hofmann elimination pathway, which is a major degradation mechanism for AEMs in high‑temperature alkaline environments. With its high ionic conductivity, mechanical robustness, extended durability, and scalable production, PAMP represents a transformative material that can significantly lower the cost of green hydrogen production and accelerate the industrialization of AEM-WE technology.
