Carbon nanomembranes (CNMs) supported by polymer: mechanics and gas permeation

Adv Mater. 2014 Jun 4;26(21):3421-6. doi: 10.1002/adma.201304536. Epub 2014 Feb 17.

Abstract

Gas permeation characteristics of carbon nanomembranes (CNMs) from self-assembled monolayers are reported for the first time. The assembly of CNMs onto polydimethylsiloxane (PDMS) support membranes allows mechanical measurements under compression as well as determination of gas permeation characteristics. The results suggest that molecular-sized channels in CNMs dominate the permeation properties of the 1 nm thin CNMs.

Keywords: buckling; carbon nanomembranes; composite membranes; gas permeation; mechanical properties.
