Functional polymeric micro/nanofibers have gained considerable interest as promising materials for the structures that are potentially beneficial in lot of application areas as they possess excellent characteristics such as large surface-area-to-volume ratio, incredibly small pore dimensions etc. Microfluidic developments have currently shown a huge amount of opportunities as revolutionary approaches to create microfiber. By carefully regulating the flow and reaction kinetics in microchannel chip, microfluidic-spinning technology can be applied to generate fibers with tailored characteristics and polymorphic structures. However, this paper features the basic mechanism of micro-fiber production by microfluidic spinning Technology (MST) as well as the principle of Elcectro-Microfluidic Spinning Technology (EMST). Besides, core-shell fiber production by MST is also described in brief. Finally, the advantageous features, application areas and challenges of MST are reviewed briefly in this paper.
