High nanoparticles loadings mixed matrix membranes via chemical bridging-crosslinking for CO2 separation

Under high nanoparticles loadings, the gas separation performance mixed matrix membranes (MMMs) could be limited by the inferior compatibility between polymer and nanoparticles. Herein, we utilized a “bridging-crosslinking” method to connect the polymer and nanoparticles via macromolecule. Specially, the poly(vinylamine) (PVAm) and UIO-66-NH2 nanoparticles were bridging-crosslinked by using poly(ethylene glycol) diglycidyl ether (PEGDE) to...
