Description
Technical field
The present invention relates to polymer nano material technology of preparing, more particularly, relate to a kind of polymer solution electrostatic spinning assembly, apparatus and method.
Background technology
Electrostatic spinning technique is the effective ways preparing polymer nano material, can obtain diameter in tens nanometers to the one dimension fibre of hundreds of nanometer.Compare conventional fibre, nanofiber has higher high porosity and specific area.This makes electrostatic spinning technique obtain investigation and application widely in filtration art.
Common single needle electrospinning device is primarily of parts compositions such as high voltage source, Spinning pumps, spinning syringe needle and collecting boaries.By high voltage source, between spinning syringe needle and collecting board, define high-voltage electrostatic field, the polymer solution droplets at spinning Needle outlet place is under the effect of electrostatic field, and shape can become taper, becomes " taylor cone ".Along with the increase of electric field force, " taylor cone " comes to a point gradually, and after cone-apex angle reaches a critical value, vertex of a cone surface molecular is subject to enough large electric field force to overcome the surface tension of solution, and polymer solution ejects from the vertex of a cone, forms injection stream.Electric field force makes jet stretch thousands of times to millions of times, and the diameter of jet is reduced to several micron to tens nanometers thereupon.Along with solvent evaporates, the fiber of gained is finally distributed on collecting board desultorily, forms nano fiber non-woven fabric.
In the electrospinning process of single needle, spinning efficiency very low (flow velocity of general spinning solution is 0.1-10mL/h), cannot meet the requirement of industrial production to production efficiency.
