Description
technical field
[0001] The invention belongs to the technical field of electrostatic spinning, and in particular relates to a high-voltage electrostatic power shuttle nano-spinning device. Background technique
[0002] Electrospinning technology is a technology in which non-Newtonian fluids generate jets under high-voltage electrostatic fields to form micron or even nanofibers. It is the most direct method that can be used to prepare organic, inorganic and composite nanofibers. Because electrospun nanofibers have good application prospects in many fields such as filtration, medicine, environment, tissue engineering, electronics, catalysis, sound absorption, and military affairs, the research on electrospinning equipment has recently become the focus of many scholars and engineering technicians around the world. One of the hot issues of personnel.
[0003] At present, the electrospinning equipment for preparing nanofibers in the laboratory mainly has the following forms: poi...
