1. Ultralarge Free-Standing Imine-Based Covalent Organic Framework Membranes Fabricated via Compression

Author

Martín-Illán, Jesús Á., Suárez, José Antonio, Gómez-Herrero, Julio, Ares, Pablo, Gallego-Fuente, Daniel, Cheng, Youdong, Zhao, Dan, Maspoch, Daniel, Zamora, Félix, Martín-Illán, Jesús Á., Suárez, José Antonio, Gómez-Herrero, Julio, Ares, Pablo, Gallego-Fuente, Daniel, Cheng, Youdong, Zhao, Dan, Maspoch, Daniel, and Zamora, Félix

Abstract

Demand continues for processing methods to shape covalent organic frameworks (COFs) into macroscopic objects that are needed for their practical applications. Herein, a simple compression method to prepare large-scale, free-standing homogeneous and porous imine-based COF-membranes with dimensions in the centimeter range and excellent mechanical properties is reported. This method entails the compression of imine-based COF-aerogels, which undergo a morphological change from an elastic to plastic material. The COF-membranes fabricated upon compression show good performances for the separation of gas mixtures of industrial interest, N2/CO2 and CH4/CO2. It is believed that the new procedure paves the way to a broader range of COF-membranes.
