On July 11, 2018, Prof. Zhang invited Professor Yunze Long of Qingdao University to visit the team and give an academic report.
    Professor Long’s report topic: Preparation and application of functional nanofibers by electrospinning.
    Report summary: Electrospinning is a technology that can directly prepare organic and inorganic continuous micro-nano fibers from solutions or melts of polymers and composite materials. Electrospun fibers have broad application prospects in wound dressings, drug carriers, filter materials, nano devices, textiles and clothing, battery separators, catalysts, etc. Our research group has controllable preparation of electrospun fibers (such as ordered arrangement, cross structure, twisted structure, spiral strands, etc.), electrospun metal oxide nanofibers and optoelectronic devices, electrospun functional polymer flexible electronic devices (such as Nano generators, artificial intelligence skins, smart textiles, etc. have been studied. In addition to electrospinning functional micro-nano fibers and devices with different morphologies and structures, we have also studied new electrospinning mechanisms, portable electrospinning devices and applications. For example, in order to avoid the pollution of the environment by the volatilization of organic solvents in traditional solution electrospinning, and the low utilization rate of spinning raw materials (about 20%), we have studied a variety of solvent-free electrospinning technologies (such as melt electrospinning, light curing electrospinning). , Thermosetting electrospinning, etc.). In particular, we have proposed an anionic curing electrospun medical adhesive. Further studies have shown that this technology can be used for rapid hemostasis in visceral surgery. Compared with traditional hemostasis techniques, this method has faster hemostasis and avoids bleeding and tissue from the wound after surgery. Adhesion, small side effects and other advantages. In addition, we have designed a variety of portable electrospinning devices, which can be used for rapid treatment or personal care in the field, as well as large electrospinning production lines. Some electrospinning equipment and nanofiber membrane filtration products have been industrialized.
