The Effects of Morphology and Hydration on Anion Transport in Self-Assembled Nanoporous Membranes.

Ordered nanoporous polymer membranes offer opportunities for systematically probing the mechanisms of ion transport under confinement and for realizing useful materials for electrochemical devices. Here, we examine the impact of morphology and ion hydration on the transport of hydroxide and bromide anions in nanostructured polymer membranes with 1 nm scale pores. We use aqueous lyotropic self-assembly of an amphiphilic monomer, with a polymerizable surfactant to create direct hexagonal (H) and gyroid mesophases.

Sulfonic-acid-based lyotropic bicontinuous cubic polymer network for molecular-size-selective heterogeneous catalysis.

A nanoporous, bicontinuous cubic, lyotropic liquid crystal polymer resin with sulfonic acid groups is presented that exhibits high catalytic activity and is capable of molecular-size-selective heterogeneous acid catalysis.
