Background technique
Preparing micro nanometer fiber by method of electrostatic spinning is one of preparation method most mature at present.According to spinning material shape
The difference of state, electrostatic spinning can be divided into solution electrostatic spinning and melt electrostatic spinning.The spinning solution of solution electrostatic spinning requires
The organic solvents such as organic solvent such as dehydrated alcohol, acetone, dimethylformamide and tetrahydrofuran, wherein most organic solvent
All there is toxicity, this there is the volatilization of solvent and recycles the problem of remaining with toxic solvent, limits solution electrostatic spinning and exists
Some applications in biomedicine.On the contrary, melt electrostatic spinning does not use organic solvent, this problem is avoided well.So
And the shortcomings that melt electrostatic spinning, specifically includes that whole device complexity, needs heating and temperature controlling device；Heating device and high press fitting
Existing electromagnetic interference problem between setting.
Basic electrostatic spinning apparatus is made of three major parts, be respectively DC high-voltage power supply, metal spinning head,
Collection device.High pressure in electrostatic spinning experiment is usually to be provided with DC high-voltage power supply, usually the direct current of 0 ~ 30kV
High voltage power supply, but ac high voltage source can be used for electrostatic spinning, only considerably less.Spinning head is connected to equipped with poly-
On the syringe of polymer solution or melt, polymer solution or melt are squeezed out with a stably and controllable rate with promoting to pump
Spinning head forms droplet-like at spinneret scalp acupuncture mouth, applies high pressure at this time, the polymer solution surface at needle mouth accumulates rapidly sense
Charge is answered, under the action of the electrostatic repulsion forces of surface charge and electric field Coulomb force, drop starts that surface tension is overcome to become to bore
Shape (taylor cone), with the increase of high pressure, electrostatic repulsion forces and electric field Coulomb force are more than the critical value of surface tension, in spinning head
Tip sprays electrified jet, and stretched and whip is dynamic in the electric field becomes elongated silk for electrified jet, as the solvent evaporates with
And it further stretches and finally obtains the other electrospinning fibre of micro/nano level in collecting terminal.Since collecting terminal is grounded, fall on collecting terminal
Charged fiber be usually formed be random alignment non-woven fabrics fiber film.
Solution electrostatic spinning and melt electrostatic spinning can be divided into according to the different electrostatic spinnings of spinning material.Solution Static Spinning
Silk there are low efficiency, organic solvent volatilization and toxicity the disadvantages of, on the contrary, melt electrostatic spinning can be very since there is no solvent
It solves these problems well.However, the device of melt electrostatic spinning is more complicated than solution electrostatic spinning.
In recent years, domestic and foreign scholars are more and more to the research of melt electrostatic spinning, especially fill to melt electrostatic spinning
The improvement set.For example, Ogata seminar invention laser melt heating electrostatic spinning apparatus can efficiently, be uniformly heated up it is poly-
Close object.Melt direct write electrospinning can accurately control deposition velocity and the direction of single fiber, and prepare stereoscopic three-dimensional bracket knot
Structure.The hand induction machine melt electrostatic spinning device of Long Yunze seminar invention is replaced conventional high-tension power supply, keeps away
The electromagnetic interference problem between electromagnetic heating and high voltage power supply is exempted from, whole device is safer, portable.Yang Weimin seminar pair
The spinning head of melt electric spinning equipment improves, and the umbrella spinning head of invention solves the problems, such as melt electrostatic spinning low output,
The high-volume melt electrostatic spinning of efficient stable may be implemented.
So that entire electrostatic spinning apparatus is become increasingly complex the improvement of electrostatic spinning apparatus at present, seriously hinders Static Spinning
The application of silk, especially outdoors or without under conditions of external power supply.In order to solve this problem, researcher also examines
Consider the heaviness of conventional high-tension power supply and the dependence to external power supply, trial substitutes traditional height using other high pressure supply equipments
Voltage source, and achieve some achievements.For example, the hand-held electrostatic spinning machine of Long Yunze seminar invention is powered using battery, it is whole
A device volume is only 10.5 × 5 × 3cm3, quality is only 120g.Hand induction machine electrostatic spinning apparatus can not only be used
In solution electrostatic spinning, melt electrostatic spinning can be also used for.In addition, the portable type solar energy electrostatic spinning of the propositions such as Yan Xu fills
Electrospinning experiment can also be carried out outdoors by setting.
