23 Jul Multi-nozzle high-voltage electrostatic spinning apparatus added with electric field shielding device
Abstract
The invention belongs to the technical field of high-voltage electrostatic spinning, in particular relates to a multi-nozzle high-voltage electrostatic spinning apparatus which simultaneously co-spinsand superimposes the mono-component or multi-component materials with multi-scale micro-/nano-fiber and multi-scale microsphere fiber and is added with an electric field shielding device. The multi-nozzle high-voltage electrostatic spinning apparatus comprises a high-voltage power supply, a feeding device, a plurality of jet devices with nozzles respectively, a collection device and electric field shielding devices added among the plurality of jet devices. An electrospinning product can be one or more of micro-fiber, nano-fiber, nanosphere and microsphere which coexist at the same time. The prepared micro-/nano-fiber film can be used as an ultra-filtration film, a tissue engineering bracket, a drug slow-release material, and the like. The rough surface formed by the micro-/nano-fiber andthe microsphere can also be applied to the fields of the super-hydrophobic material, and the like. The method has the advantages of simple operation, wide application, relatively low cost, and the like, and has favorable application and generalization value.
