Abstract

The invention discloses a melt electrostatic spinning device and method based on calculus cascade, and belongs to the field of electrostatic spinning. The melt electrostatic spinning device comprises melt conveying devices, connection flanges, a junction device, cascade devices, an inner cone shunting type nozzle, a high-voltage electrostatic generator, base cloth, a solvent tank and an air heating system. Molten polymer fluid is cascaded through the cascade devices and manufactured to be multiple layers of alternated composite materials, and therefore the thickness of each layer of composite material is decreased; the inner cone shunting type nozzle is used, and the inner cone face structure enables melts to achieve the re-shunting process naturally; the hot gas auxiliary structure is used, hot gas is shot towards the inner cone at a high speed by even spraying airflows, and the function of thinning the inner cone is achieved. The melt electrostatic spinning device is combined with the cascade devices, the thickness of the melt layers is decreased through the uniqueness of the alternated cascading of the cascade devices, and a new method is provided for producing nano-scale fiber products.

Description

technical field

[0001] The invention relates to a calculus-based laminated melt electrospinning device and method, belonging to the field of electrospinning. Background technique

[0002] In recent years, many methods for preparing nanofibers have been developed, such as stretching, template polymerization, phase separation, self-organization, electrospinning, etc. Among them, the electrospinning method is currently the only method that can directly and continuously prepare polymer nanofibers. The electrospinning process is to apply a high-voltage electric field between the nozzle and the receiving device at the supply end of the solution or melt, so that the charged solution or polarized melt forms a Taylor cone under the action of the electric field force, and then overcomes the surface tension to form Jet, the process of obtaining microfibers on a receiving device.

[0003] Electrospinning is divided into melt electrospinning and solution electrospinning. Compared with...
