On the Order and Orientation in Liquid Crystalline Polymer Membranes for Gas Separation.

ABSTRACT: To prevent greenhouse emissions into the atmosphere, separations like CO₂/CH₄ and CO₂/N₂ from natural gas, biogas, and flue gasses are crucial. Polymer membranes gained a key role in gas separations over the past decades, but these polymers are often not organized at a molecular level, which results in a trade-off between permeability and selectivity. In this work, the effect of molecular order and orientation in liquid crystals (LCs) polymer membranes for gas permeation is demonstrated. Using the self-assembly of polymerizable LCs to prepare membranes ensures control over the supramolecular organization and alignment of the building blocks at a molecular level. Robust freestanding LC membranes were fabricated that have various, distinct morpholo
