Abstract

The invention discloses a petal-shaped nanofiber production device and method. The device comprises a petal-shaped spinning nozzle, a high-voltage spinning power supply and a nanofiber collecting device, wherein the petal-shaped spinning nozzle is used for spraying spinning liquid into spinning jet flow; the high-voltage spinning power supply is used for enabling the petal-shaped spinning nozzle to generate static electricity; and the nanofiber collecting device is used for collecting the spinning jet flow sprayed by the petal-shaped spinning nozzle. The production method comprises the following steps: filling the petal-shaped spinning nozzle with spinning liquid; switching on the high-voltage spinning power supply and adjusting spinning voltage; exciting the spinning jet flow from the surface of the petal-shaped spinning nozzle; and receiving the continuous spinning jet, namely nanofibers, by using the nanofiber collecting device. According to the petal spinning nozzle, equal jet drawing electric field force can be generated at the tip end of the nozzle, meanwhile, the generation number of the electrostatic spinning jet flow is greatly increased, and nanofiber aggregates with quite uniform diameter can be obtained.

Description

technical field [0001] The invention relates to a petal-shaped nanofiber production device and method, belonging to the field of nanofiber production. Background technique [0002] With the research and development of nanotechnology, electrospinning technology, which can quickly obtain fibers with a diameter distribution from several nanometers to several micrometers, has developed rapidly in the past 20 years. The nanoscale fiber prepared by it has a large specific surface area, rich pore structure, flexible surface functionalization characteristics and superior interface and surface effects. Electrospinning technology is therefore widely used in energy, environment, biological science, medical engineering, military and national security and other fields. [0003] Existing electrospinning devices mainly include traditional single-needle electrospinning devices and new needle-free electrospinning devices. The traditional single-needle electrospinning device is mainly compo...
