Problems solved by technology

[0004] Electrospinning technology is a technology in which a non-Newtonian fluid polymer solution overcomes surface tension and viscoelastic force under a high-voltage electric field, and performs stretching and bending motions to obtain nanometer to submicron fibers; this technology has simple equipment, low production cost, and is easy to use. Wide range of materials and large specific surface area; At present, there have been reports at home and abroad on the use of coaxial electrospinning devices to prepare metal oxides, but the coaxial electrospinning devices are relatively complicated, and there are difficulties in the selection of solvents and the setting of spinning parameters , while uniaxial electrospinning overcomes the above deficiencies
