23 Jul Electro-spinning micro-nanofiber device and method for preparing micro-nanofiber
Abstract
The invention provides an electro-spinning micro-nanofiber device and a method for preparing a micro-nanofiber and belongs to the field of biological materials and tissue engineering. The electro-spinning micro-nanofiber device comprises a high-voltage power supply, receiving devices, a porous spinning jet and a rotary motor, wherein the porous spinning jet is of a hollow cylindrical structure, and the hollow part is an electro-spinning stock solution storage groove capable of accommodating an electro-spinning stock solution; a plurality of spray orifices are formed in the surface of the porous spinning jet; one pole of the high-voltage power supply is connected with the receiving devices, and the other pole of the high-voltage power supply is connected with the porous spinning jet; the rotary motor drives the porous spinning jet to rotate. By virtue of the porous device, the yield can be improved, and micro-nanofibers with uniform directivity are obtained. Meanwhile, the required application voltage can be greatly reduced, and the method for adjustment and control of the more uniform spinning directivity through a single step is also provided.
