Abstract
The invention relates to a hole-in-hole nozzle with uniform electric field, which comprises a main body plate and an auxiliary plate, the main body plate is insulated and has a contact angle with water >90°, the main body plate is provided with holes, and more than one liquid guide is inserted on the auxiliary plate All the catheters are inserted into the channel, and the part inserted into the channel is insulated; different catheters are independent or nested with each other, and cooperate with the channel to form a plurality of through holes, and the plurality of through holes include channel holes The through hole surrounded by the wall and all catheter walls, the through hole surrounded by any two catheter walls nested with each other, and the through hole inside the catheter that is not nested inside, different The through holes communicate with different solution channels respectively. The hole-in-hole nozzle with uniform electric field of the present invention has a simple structure and is convenient to use. Uniformity of nanofibers.
Description
technical field [0001] The invention belongs to the technical field of electrostatic spinning devices, and relates to a hole-in-hole nozzle with uniform electric field, in particular to a hole-in-hole two-component nozzle with even electric field distribution. Background technique [0002] Electrospinning technology is a process that can use a high-voltage electrostatic field to control the shape and specification of fibers to manufacture nanofiber webs or continuous fibers that are aligned. This technology is to overcome the surface tension of the polymer solution or melt under a high-voltage electrostatic field of several thousand volts to tens of thousands of volts to generate a charged jet flow. The solution or melt dries and solidifies during the spraying process, and finally falls on the receiving device Form fiber mats or other shapes of fiber aggregates. Due to its high specific surface area and large porosity, electrospun nanofibers have been widely used in the fie...
