Recent advances in microfluidic fiber‐spinning chemistry

Abstract Fiber‐spinning chemistry (FSC) has emerged as a promising micro‐reaction platform due to its high‐specific surface area, efficient heat and mass transfer, and enhanced reaction rate. The FSC strategy employs spinning fibers as microreactors, lessening the emissions of volatile organic compounds (VOCs), and realizing the design of micro/nanoscale fibers and the synthesis of nanomaterials. In this review, we highlight the latest advancements in FSC in respect of preparation mechanisms and technical advantages. Various FSC strategies, including microfluidic spinning, electro‐microfluidic spinning (EMS), and microfluidic blow spinning (MBS) are emphasized. In particular, the regulation of microfluidic chips in the FSC process is introduced. Additionally, the application of the FSC strategy is summarized in the synthesis of fluorescent nanomaterials, nonweaving for multidimensional fibers, and all‐weather smart textiles. Finally, the advanced progress and future perspectives are discussed. Overall, this review will provide theoretical guidance for the design of well‐defined micro/nanoscale fibers based on the FSC platforms.
