Description

technical field [0001] The invention relates to the field of material preparation, in particular to an electrostatic spinning system and an electrostatic spinning method. Background technique [0002] Electrospinning technology is a special fiber preparation process, which uses the breakdown effect of high-voltage electrostatic field on polymer solution to prepare micro-nano fiber materials. The tapered end of the silk liquid forms a jet and is stretched in an electric field, finally forming nanofibers in a non-woven state on the receiving device. In the electrospinning process, a high-voltage power supply is required to provide an electrostatic field, and the required power supply voltage is high and the current is small. However, in order to achieve this purpose, the existing high-voltage power supply used in electrospinning requires complex conversion circuit components. Contents of the invention [0003] The purpose of the present invention is to provide a system and ...
