A high performance O2 selective membrane based on CAU-1-NH2@polydopamine and the PMMA polymer for Li–air batteries†
Abstract
A novel mixed matrix membrane (MMM) was prepared by incorporating polydopamine-coated metal organic framework (MOF) crystals of CAU-1-NH2 into a PMMA (polymethylmethacrylate) matrix. The MMM possesses the advantages of high O2 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.
