Innovative Multifunctional Micro-Nanoscale Fiber Construction Approach and Its Application

Microfluidic spinning technology (MST) is an ideal microreactor platform for making anisotropic ordered microfibers due to the advantages of large area/volume ratio, high heat transfer and mass transfer, homogeneous mixing and so on, and it has become one of the general technologies for resolving important confinement issues in industries such as smart chips, tactile sensors, gene sequencing, and new energy. Among them, in the field of new energy storage, fiber materials produced by traditional methods have poor structural regulation, uncontrolled composition, low power coupling etcetera, resulting in the hindrance of ion transport and interfacial charge transfer, thus greatly reducing the energy density. To this end, we systematically introduce a series of Microfluidic Spinning, Microfluidic Electrospinning and Microfluidic Blow-Spinning technology to construct advanced nanofiber materials with ordered microstructures, large specific surface areas, porous channels and high electrochemical activity, which have solved the key problems of electron conduction, ion transport, and storage, realized fiber energy storage devices with high energy density and mechanical flexibility, and provided an effective way for the innovation, development and industrialization in the field of new energy in the chemical industry.

In addition, MST was combined with microfluidic chips to construct multifunctional ordered microfibers and applied to microreactors, fluorescence coding, optical sensing and multi-signal analysis. Starting with the structural controllable characteristics of ordered fiber materials prepared by MST, we have realized the application of ordered microfibers in microreactors, supercapacitors, wearable devices, food packaging, artificial skin, artificial blood vessels and other biomedical materials, and laid the foundation for multifunctional microfibers constructed by MST. Besides, to realize large-scale nanofiber membranes, we also investigated large-area degradable nanofiber skin scaffolds constructed based on Microfluidic Blow-Spinning technology for artificial biological skin tissue application, then for the first time used the method of droplet microfluidic reaction to prepare micro-mesoporous carbon skeleton nanohybrid electrode materials with homogeneous ordered structure continuously by the rapid reaction of elementary in the microdroplet confined domain space.
