However, there are only a few electrohydrodynamic methods without spinnerets at present, and the only one is to use the vertical magnetic field to act on the sharp needle-like protrusions perpendicular to the surface formed by the disturbance effect of the free surface of the magnetic fluid. The method is combined to form a new electrohydrodynamic method without spinnerets. However, due to the small boosting effect of this method, people only obtain a small amount of ultrafine fibers through this method.

Embodiment 1
[0053] The electrohydrodynamic method of the centrifugal force type electrohydrodynamic method of spraying the material to be processed without a spinneret such as figure 1 shown. The processed material is sprayed onto the roller 4 through the processed material shower assembly 3b, and when the roller rotates, the showered processed material 3c is subjected to centrifugal force through the sharp protrusion 4a on the edge of the roller. The roller was connected to a high-voltage power source 1 as the working electrode 1b, and the counter electrode was combined with the collection device 1a. When a high-voltage electric field is applied and the roller rotates, the material 3 to be processed is simultaneously subjected to centrifugal force and electrostatic force to form an electric jet 2, thereby processing the material to be processed.
Embodiment 2
[0055] The electrohydrodynamic method of the roller hitting type electrohydrodynamic method for the material to be processed without a spinneret is as follows: figure 2 Department shown. The fluidized processed material 3a is located in the container 3 below the roller, and when the roller 4 rotates, the processed material adheres to the roller, and receives centrifugal force at the sharp protrusion 4a on the edge of the roller. The roller is connected to a high-voltage power source 1 as the working electrode 1b, and the counter electrode is combined with the collection device 1a. When a high-voltage electric field is applied and the roller rotates, the two processed materials 3a-a and 3a-b are simultaneously subjected to centrifugal force and electrostatic force to form an electric jet 2, thereby processing the two processed materials simultaneously.
Embodiment 3
[0057] The system structure of spinnerless rotary disc centrifugal electrohydrodynamic method is as follows: image 3 shown. The fluidized material 3 to be processed is guided to the turntable 4, and when the turntable rotates, the material to be processed goes along the guide groove 4a on the turntable to the sharp protrusion 4b on the edge of the turntable to obtain centrifugal force. Connect the turntable to a high-voltage power source 1 as the working electrode 1b, and the counter electrode is combined with the collection device 1a. When a high-voltage electric field is applied and the turntable rotates, the material 3 to be processed is simultaneously subjected to centrifugal force and electrostatic force to form an electric jet 2, thereby processing the material to be processed.

Abstract
The invention relates to an interface assistant spinneret-free electrofluid mechanics method, in particular to a method for applying a force to a spinneret-free electrofluid mechanics interface namely a starting jet flow interface of a charged and processed material so as to assist the charge fluid to break through the surface tension of the electrofluid mechanics interface and the mutual acting forces in the fluid to process and deal with a processed material, in addition to an electrostatic force, and a selectable acting force, of which the vertical magnetic field acts on a sharp needle-shaped bulge vertical to a surface layer and formed by the perturbation effect on the free surface of a magnetic fluid, which adapts to the charged fluid motion direction namely a direction that the direction of an acting force is the same as that of an electric jet flow or has the same direction component. The method suitable to serve as the method for preparing a superfine material which has one or more functions including separation, protection, antibacterium, deodorization, catalysis, sensing, decoration, structure supporting, biocompatibility, storage, controllable release, electric conduction, restoration, medical treatment, health care, intelligent response, redolence and adhesion. The prepared superfine material is applied to structures of solid, hollow or nuclear shell structured particles, fibers, thin films, cloth blocks or block structures, and can be processed with low cost on a large scale.
