Abstract

The invention provides an electrostatic spinning device high in yield. The electrostatic spinning device mainly comprises a metal jetting device (1), a solution feeding system (2) and an arc receiving system (3). The electrostatic spinning device is characterized by comprising the solution feeding system (2) capable of feeding a solution at any position of the metal jetting device (1). The electrostatic spinning device can be used for spinning multiple kinds of organic matters or organic-inorganic compounds, the spinning efficiency is quite high, the capacity is more than three magnitude orders higher than that of a single-nozzle spinning device, and the spinning efficiency of the electrostatic spinning device is the highest among that of similar devices at present.

Description

technical field [0001] The invention belongs to the field of material preparation equipment, and in particular relates to an electrostatic spinning equipment and a method for preparing electrostatic spinning using nozzleless spinning technology, multi-angle solution supply and arc receiving. Background technique [0002] The electrospinning method has obvious advantages such as simple process, fast preparation, low cost, and environmental friendliness. It is considered to be one of the most promising technologies for the industrial production of nanomaterials. The basic principle of electrospinning is: the polymer solution or melt is placed in a high-voltage electrostatic field, so that it is charged with high-voltage static electricity, and the charged solution forms a Taybr cone at the apex of the droplet under the action of the electric field force and surface tension. When the electric field When the force is greater than the surface tension of the solution, a thin jet s...
