Polymer ultrapermeability from the inefficient packing of 2D chains
Polymer membranes were formed from the inefficient packing of 2D polymer chains in a 3D amorphous solid, forming small and large micropores that enable high gas selectivity and permeability. This strategy may be applied to other polymers.
