Ultra-fast, Selective CO2 Permeation by Free-standing Siloxane Nanomembranes

Chemistry Letters 2019, 48 (11), 1351-1354

Detailed description

Fabrication and gas permselective behavior of free-standing polydimethylsiloxane (PDMS) nanomembranes is discussed. The largest CO2 permeance is close to 40,000 GPU (the highest one ever reported) at 34-nm membrane thickness without losing the CO2/N2 selectivity of 10–12, indicating the formation of pin-hole free nanomembranes.
