Multi-layer composite hollow fiber membranes derived from poly(ethylene glycol) (PEG) containing hybrid materials for CO2/N2 separation

With the aim to make newly developed materials to be more industrially relevant, multi-layer composite hollow fiber membranes were molecularly designed by surface coating ultrathin layers of a poly(ethylene glycol) (PEG) containing hybrid material onto the polyethersulfone (PES) porous substrate for CO2/N2 separation. The asymmetric PES hollow fiber substrate was prepared by a dry-jet wet spinning process. Multiple ultrathin layers of the PEG...
