| Abstract: | Reactive spinning of nano‐ and microfibers that involves very fast chemical reactions and ion exchange is a challenge for the common methods for nanofiber formation. Herein, we introduce the reactive magnetospinning method. This procedure is based on the magnetic‐field‐directed collision of ferrofluid droplets with liquid droplets that contain complementary reactants. The collision, start of the chemical reaction, and the fiber drawing are self‐synchronized. The method is used to synthesize, cross‐link, and chemically modify fiber‐forming polymers in the stage of fiber formation. The method provides new opportunities for the fabrication of nanofibers for biomedical applications. |
