Janus Membranes with Asymmetric Wettability for Fine Bubble Aeration

A superaerophobic-hydrophobic Janus membrane is fabricated by single-sided polydopamine/polyethyleneimine codeposition. The Janus membrane significantly promotes fine bubble generation and gas/liquid mass transfer. Its application is exemplified by highly efficient dopamine oxidization and enzymatic CO2 hydration. The Janus membrane aerator shows great potential in many gas-involved energy generation and environmental remediation processes.
