Abstract

Fabrication and gas permselective behavior of free-standing polydimethylsiloxane (PDMS) nanomembranes are 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 1012, indicating the formation of pin-hole free nanomembranes.
