Enhanced interfacial polarization loss induced by hollow engineering of hollow alloyed CoFe-ZIF nanocages/carbon nanofibers for efficient microwave absorption

Hollow alloyed CoFe-ZIF/CNF composite fibers were successfully synthesized. The carbon fiber with dielectric loss wraps hollow alloyed CoFe-ZIF nanocages with magnetic loss to form a bamboo-shaped composite fiber to achieve magnetoelectric synergy.
