英文摘要: Abstract(#br)This study finds that a layer of a specific surfactant pair appended to the nanopores in a skinned carbonaceous composite membrane (CnCM) could impact the nanofiltration (NF) capability of the membrane. A CnCM is derived from a methacrylate copolymer coating that composites with a low dose of polymer microspheres. The microspheres have the core-shell structure with polyfurfurylalcohol core and a thin polydopamine shell (PDA@PFA). The polymer coating on a porous stainless-steel substrate is converted to the skinned CnCM through a controlled pyrolysis treatment in a reducing atmosphere. The interface between the microspheres and the carbonaceous matrix prevails the permeation. The functionalities present on the microspheres after pyrolysis thus equip pores with polar group...
