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.

摘要

首次报道了自组装单分子层的碳纳米膜（CNMs）的气体渗透特性。将 CNMs 组装到聚二甲基硅氧烷（PDMS）支撑膜上，允许在压缩下进行机械测量以及确定气体渗透特性。结果表明，CNMs 中的分子大小的通道主导着 1nm 厚的 CNMs 的渗透性能。
