Fiber, coaxial fiber and doughnut etc..
Instrument currently used for electrostatic spinning substantially can be with three categories：The first kind is the electrostatic spinning machine for having syringe needle, will be quiet
Anode in electric field is added in needle end, formation taylor cone at syringe needle is acted on by electrostatic force, to obtain nanofiber；The
Two classes are the electrostatic spinning machines of needle-less, such as drum-type electrostatic spinning machine, are equipped with a large amount of spinneret orifice within one week in drum shaft, lead to
Cross the effect of electrostatic field, spinning-drawing machine can large area, the preparation spinning film of cycle；Third class is bubble electrostatic spinning machine, bubble
Electrostatic spinning process be createed by the inspiration of spider spinning principle, once load high voltage electric field, the charge in solution
It is induced by electric field, moment is distributed in bubble surface, and charge and the electric field of bubble surface, which intercouple, generates shearing stress, and bubble becomes
Shape forms taper bubble, and when electric field strength reaches threshold value, the electric field force that bubble is subject to is enough to overcome bubble surface tension, gas
Bubble is stretched rupture, and electrified jet moment is spouting from bubble top, broken bubble film with high initial velocity and
Acceleration, be stretched refinement under electric field force effect, flies to cathode.And remaining bubble chamber film is shunk, surface charge redistribution,
New bubble continues to generate, and repeats the above process.
To sum up, it has been prepared currently used for preparing the electrostatic spinning machine of superfine fibre and nanofiber, but still
So there is a problem of certain.One, in progradation, the polymer solution of thawing is easy and propeller contact；Two, electrostatic spinning
Sample be mostly high polymer, before spinning, need high polymer being dissolved in liquid flux, such as organic solvent, water etc., due to high polymer
Molecular weight it is big, dissolving need be up at least two time more than hour；Three, electrostatic spinning machine can only to liquid high polymer into
Row spinning can not directly use solid superpolymer sample, there is the high polymer of surface modification really in an experiment, need directly to melt
Spinning is handled；Four, at present due to electrostatic spinning machine can only handling liquid samples, most of high polymers need to be dissolved in organic solvent into
Row dissolving, such as, DMF, THF, chloroform etc. is due to low boiling point during electrostatic spinning, and a large amount of to volatilize, formation is more for organic solvent
Hole fiber requires height, the few fiber in aperture very not applicable for preparing strength；Five, for there is the electrostatic spinning machine of syringe needle, due to
High polymeric solution viscosity is higher, and syringe needle number is small, easily blocks and needle adjacent electrostatic interference has certain defect.
