Polymer membranes with high gas permeability.

CO2-Responsive polymer membranes with gas-tunable pore size.

We report a smart polymer membrane whose pore can be switched between the "closed" and "open" state just by passing CO2 and Ar in solution respectively. Compared with other stimuli, such as pH or temperature change, gas is an environmentally friendly and cost-effective stimulus for reversibly tuning the pore size and imparting the size selectivity of the membrane.

Mixed matrix membranes prepared from high impact polystyrene with dispersed TiO2 nanoparticles for gas separation

The current study presents synthesis and characterization of high impact polystyrene - TiO2 nanoparticles mixed matrix membranes for separation of carbon dioxide from nitrogen. The solution-casting method was used for preparation of membranes. The nano mixed matrix membranes were characterized using scanning electron microscopy to ensure the suitable dispersion of nano particles in high impact ...

Gyroid nanoporous membranes with tunable permeability.

Understanding the relevant permeability properties of ultrafiltration membranes is facilitated by using materials and procedures that allow a high degree of control on morphology and chemical composition. Here we present the first study on diffusion permeability through gyroid nanoporous cross-linked 1,2-polybutadiene (1,2-PB) membranes with uniform pores that, if needed, can be rendered hydrop...
