Abstract

Flexible polydopamine–Co_0.3Ni_0.7Fe₂O₄@SiO₂ NFMs with a hierarchical structure and strong magnetism were prepared by gelation, calcination and dopamine self-polymerization on electrospun SiO₂ NFMs. The resulting membranes displayed a short response time (10 min/80%), high adsorption capacity and excellent adsorption affinity (97%) for methyl orange capture.
