Induced polymer crystallinity in mixed matrix membranes by metal-organic framework nanosheets for gas separation

Abstract

The induced crystallinity behavior of the polymer of intrinsic microporosity (PIM-1) matrix in mixed matrix membranes (MMMs) by a novel class of two-dimensional (2D) metal-organic framework nanosheets, i.e., NUS-8-COOH, is demonstrated. The proposed ideal of enhanced crystallinity induced by NUS-8-COOH nanosheets can be extended to other classes of 2D nanosheet-containing MMMs, thus opening up plentiful opportunities for constructing MMMs with superior interfacial compatibility toward enhanced gas separation performance.
