Description

technical field [0001] The invention relates to the field of nanofiber production, in particular to a nanofiber production system combined with centrifugal electrospinning, which is particularly suitable for improving production efficiency. Background technique [0002] Nanofibers refer to ultrafine fibers with a diameter of tens to hundreds of nanometers, which have unique advantages that other fibers cannot possess, such as very large specific surface area, ultrafine porosity, and good mechanical properties. In recent years, nanofibers have been widely used in textile materials, tissue engineering scaffolds, drug delivery, filter media, artificial blood vessels, biochips, nanosensors, optics, composite materials and other fields. [0003] The preparation of nanofibers has attracted the attention of experts and scholars at home and abroad. So far, there are many methods for preparing nanofibers, such as stretching method, microphase separation, template synthesis, self-ass...
