Abstract

The development of high-performance membranes is of pivotal importance for practical gas separations. However, it is challenging to prepare defect-free thin membranes. In this study, high-performance composite membranes were prepared based on a thin mixed matrix membrane (MMM) selective layer composed of a poly(vinyl chloride)-poly(oxyethylene methacrylate) (PVC-POEM) graft copolymer and ZIF-8 nanoparticles on a macroporous alumina support, via a spin coating technique. The high CO₂ affinity of PVC-POEM with its amphiphilic microphase-separated structure, and the high gas diffusivity of ZIF-8 with its unique porosity and large surface area, enabled the membrane to facilitate gas separation effectively, leading to high permeance and selectivity.
