| Abstract: |
| In this paper, by sol-gel process, using the principle of electrostatic spinning machine, using polyvinyl alcohol (350 mesh), hereinafter referred to as PVA, and inorganic LiMn2O4 as the forebody, the composite nanofibers containing inorganic LiMn2O4 were prepared, which provided a new way for the preparation of composite inorganic nanofibers. In this paper, the influence of the concentration of PVA on the fiber tracing characteristics was studied systematically. A large number of literatures proved that the best concentration of PVA solution for spinning was about 8.0wt%. In the process of the experiment, with the increase of PVA concentration, the diameter of the fiber formed by it will also gradually increase, and the solution viscosity will gradually increase, which will make the solvent volatilization becomes more and more difficult, the surface of small liquid beads is difficult to form an ideal "Taylor cone"; The voltage is too low, the sample solution cannot be spun, and drops of water fall on the needle. If the voltage is too high, there will be a rosary shape on the fiber, which will hinder the appearance of the sample during electrospinning. |
