A hypothetical structure-optimized adsorbent packing with hierarchical pores and submicron features will facilitate mass transfer to adsorption sites. SEM image of porous fluoropolymer

LLNL researchers have developed a self-supporting structural material that promises more efficient carbon capture specifically from air, but generally from all CO2 containing gas sources. The material is produced with a liquid high-amine-content precursor polymer that is functionalized by adding on polymerizable end groups.

Small-angle X-ray scattering (SAXS) data of crosslinked polyelectrolyte membrane films formed under different equilibrium humidity conditions

LLNL researchers have developed a method to enhance the performance of polyelectrolyte membranes by using a humidity-controlled crosslinking process which can be applied to precisely adjust the water channels of the membrane.

Second skin smart protection mechanism of responsive nanotube membranes against environmental threats

LLNL researchers have developed an alternative route to protective breathable membranes called Second Skin technology, which has transformative potential for protective garments. These membranes are expected to be particularly effective in mitigating physiological burden.
