  • The deleterious effects of climate change due to atmospheric CO2 are being felt around the globe. To mitigate this threat, gas separation membranes possessing high CO2 permeability and selectivity are required. We report that the morphologies and gas transport properties of dense polymer membranes composed of a midblock-sulfonated block polymer are sensitive to casting solvent and relative humidity. We further establish that submersion of these membranes in liquid water alters the membrane morphology and improves CO2 permeability and CO2/N2 selectivity, with CO2 permeabilities and CO2/N2 selectivities reaching 482 Barrer and 57, respectively. These membranes are therefore promising for CO2 capture.

  • Anisotropic nanoparticles made from block copolymers are important building blocks for synthetic hierarchical materials. Here, the authors report a reversible coordination-driven self-assembly strategy for the preparation of micron-scale fibres and macroscopic films based on monodisperse cylindrical micelles.
