A high performance O sub(2) selective membrane based on CAU-1-NH sub(2) polydopamine and the PMMA polymer for Li-air batteries

A high performance O sub(2) selective membrane based on CAU-1-NH sub(2) polydopamine and the PMMA polymer for Li-air batteries

A novel mixed matrix membrane (MMM) was prepared by incorporating polydopamine-coated metal organic framework (MOF) crystals of CAU-1-NH sub(2) into a PMMA (polymethylmethacrylate) matrix. The MMM possesses the advantages of high O sub(2) permeability, high capability of carbon dioxide capture, and...

Zusammenfassung:A novel mixed matrix membrane (MMM) was prepared by incorporating polydopamine-coated metal organic framework (MOF) crystals of CAU-1-NH sub(2) into a PMMA (polymethylmethacrylate) matrix. The MMM possesses the advantages of high O sub(2) permeability, high capability of carbon dioxide capture, and excellent hydrophobic behavior. The MMM was assembled in the Li-air batteries which displayed promising electrochemical performance in the real ambient air with 30% relative humidity.
