Gating Gas Permeability Through Dynamic Cracking of Liquid Crystal Polymer Membranes.

ABSTRACT: Intelligent membranes promise transformative advances in real-time control of substance permeation, surpassing current technologies through their intrinsic adaptability to environmental stimuli. In this work, a material-regulated approach to dynamically control substance permeation, such as gas, using hybrid bilayer membranes composed of gold-coated liquid crystal oligomer networks (Au-LCONs), is established. Thermally driven LCON actuation induces a stress mismatch at the LCON-Au interface that cracks the Au layer, effectively opening "gates" in the impermeable Au to allow gas transport through the membrane; this reversible effect can be precisely controlled with temperature, facilitating the use of this system for triggering gas-mediated chemical reactions on demand. Furthermore, switcha
