Mixed Matrix Membranes Based on Torlon and ZIF-8 for High-Temperature, Size-Selective Gas Separations.

Torlon is a thermally and plasticization-resistant polyamide imide characterized by low gas permeability at room temperature. In this work, we aimed at improving the polymer performance in the thermally-enhanced He/CO and H/CO separations, by compounding Torlon with a highly permeable filler, ZIF-8, to fabricate Mixed Matrix Membranes (MMMs). The effect of filler loading, gas size, and temperature on the MMMs permeability, diffusivity, and selectivity was investigated.
