Investigation into the role of electrospinning nanofiber technology based on controlled magnetic-electric field

The diameter of nanofibers as smaller than that of the cells and thin film material field. In the field of medicine, nanofibers with simulate the structure and biological function of natural extracellular matrix, providing the possibility for human tissue and organ repair. With the new energy batteries, the preparation of battery separator materials as effectively reduce the nanofibers diameter and become an effective way to improve the filtration performance of nanofibers filters. By precisely regulating the micro-structure of the nanofibers and combining with the material via lower surface energy, the material with super hydrophobic properties as finally obtained. With MEMS, nanofibers have the higher specific surface area and microscopic porosity, which as increase the interaction area between the micro and nano sensing material and the flexible film material as-detected, and greatly improve the sensor performance. Based on the design parameters of the spinning orientation of alternating magnetic-electric field coupling technology, the characteristics of the coupling field were analyzed numerically. The drum collection device was designed for electrostatic spinning experimental machine to observe the orientation characteristics of spinning. The spinning orientation characteristics under different process parameters were studied by SEM characterization. The experimental results show that the spinning has better orientation in alternating magnetic-electric field coupling environment. The deposition area and region applying various magnetic field values as 1.4 (mT), 3.55 (mT), 4.6 (mT), 5.3 (mT), 8.5 (mT). The time-harmonic “magnetic-electric field” coupling electrostatic spinning machine described in this project adds the magnetic control module and the synchronous module to the controlled magnetic-electric field technology of electrostatic spinning, which retains with original technical advantages of electrostatic spinning and makes up for the disadvantages of randomness and poor stability of electrostatic spinning. Moreover, through the improvement of stability, the cost of raw materials and maintenance costs will be reduced in the further. Therefore, the new technologies and products adopted in this project have technical potential in both horizontal and vertical comparison.
