A general strategy for fabricating flexible magnetic silica nanofibrous membranes with multifunctionality

Flexible, magnetic, and hierarchical porous NiFe2O4@SiO2 nanofibrous membranes were prepared by combining the gelatin method with electrospun nanofibers. The membranes exhibited prominent mechanical strength and mesoporosity, as well as multifunctionality of magnetic responsiveness, dye adsorption, and emulsion separation.
