Description

technical field [0001] The invention belongs to the technical field of drug delivery devices, in particular to a novel drug delivery electrostatic spinning device. Background technique [0002] Electrospinning is one of the simplest and most efficient methods for preparing nanofibers. Compared with traditional nanomaterial preparation techniques, it has the advantages of simple processing equipment, wide source of raw materials, low spinning cost, and large-scale preparation. In recent years, it has been widely studied and reported at home and abroad. Nanofibers prepared by electrospinning technology have excellent characteristics such as high specific surface area, large length / diameter ratio, and unique physical and chemical properties. The field shows great application potential. The principle of electrospinning is very simple. It is briefly described as follows: under the action of a high-voltage electric field, the polymer solution or melt at the spinning nozzle is ej...
