In the thriving field of nano-materials science, the nanofibrous structure with immobilizednanoparticles (NPs) inside or outside of the fibers currently received great interest for their potential synergic effects. In the cooperative combining strategy, electrospun nanofibers in a tailored manner are promising materials as a platform to mutually gain both advantages of the interconnected fibrous structure and unique properties of NPs. Herein, we presented the one-step fabrication method for in-situ synthesis of novel uprightly stood extra-long hierarchical multi-metallic (Fe/Cu/S) nano-needles (NNs) on polyurethane (PU) electrospun nanofibers (PU@FeCuS). The multi-metallic nanostructures (FeCuSNNs) were in-situ synthesized by simply immersing PU nanofiber into the supersaturated FeSO4/CuSO4 solution. The results of SEM, FE-SEM, EDX mapping and 3D rendering model simulation with CAE software revealed the morphology, the composition of FeCuSNNs, and the significantly increased surface area. The possible crystallization mechanism of the formation of NNs was discussed.
