Single Capillary Electrospinning of Magnetic Core-shell Nanofibers
Various hierarchical structures (e. g. hollow, core‐shell, etc.,) have been synthesized by coaxial or multi‐fluidic compound‐jet electrospinning. However, the setup is complex and the parameters need to be carefully controlled. Herein, we report the creation of CoAl0.1Fe1.9O4 (CAF) solid, core‐shell, and hollow nanofibers via a single capillary electrospinning in combination with a controllable pre‐drying process of precursor nanofibers. The formation mechanism were outlined by investigating their morphology and microstructure in response to different experimental conditions. Moreover, these CAF core‐shell nanofibers were demonstrated the highest HC as compared to their solid and hollow nanofibers due to the enhanced magnetic surface anisotropy. The present single capillary electrospinning is not only a universal and effective method, but also can be readily extended to fabricate other materials with multi‐hollow structure.
