Abstract

The invention discloses a gravity-following cylindrical electrostatic spinning device and method. The device comprises a cylindrical spray head, a cylindrical liquid supply device with a notch is arranged in the cylindrical spray head and connected with a solution propeller at the outer side of the cylindrical spray head through a hose, and a shell of the cylindrical spray head is connected with ahigh voltage generator. The spinning method comprises the steps that the solution propeller is turned on, a solution is injected into the cylindrical liquid supply device through the hose, and when the liquid surface of the solution exceeds the notch of the cylindrical liquid supply device and the solution overflows, the portion between the cylindrical spray head and the cylindrical liquid supplydevice is filled with the spinning solution; the high voltage generator is turned on and applies positive voltage to the cylindrical spray head, and jet flows are formed on the spinning surface and quick move towards a metal rolling cylinder under the effect of electric field force; along with volatilization of a solvent, the jet flows are deposited on the surface of the metal rolling cylinder atlast. According to the gravity-following cylindrical electrostatic spinning device, the overflow-type liquid supply device controls the solution, electric charge accumulation is generated in the edgeof a gap in the cylindrical surface, and accordingly electrostatic spinning in the gravity-following direction is achieved.

Description

technical field [0001] The invention relates to a gravitational cylindrical electrostatic spinning device and method, belonging to the technical field of electrostatic spinning and textile machinery. Background technique [0002] Electrospinning is one of the most effective ways to prepare nanofiber materials. Compared with the preparation techniques of nanomaterials such as stretching method, template synthesis method, and self-assembly, electrospinning has the advantages of simple operation, short preparation process, and wide selection of materials. advantage. Compared with traditional textile fiber materials, due to their extremely small scale, nanofibrous materials have many characteristics that are difficult to exhibit at large scales, such as obvious surface and interface effects, unique small size effects, large specific surface area and extremely large size. high porosity etc. Therefore, nanofiber materials have a wider range of applications, such as air filtratio...
