Description
Technical field
The present invention is used for nano fiber scaffold technical field, more particularly to a kind of negative pressure array centrifugation pneumoelectric spinning dress
Put.
Background technology
Electrospinning is to prepare the effective ways of nanofiber.Fibre diameter generally between tens nanometer between a few micrometers, with
The adjoining dimensions of the fibrous framework such as collagen in extracellular matrix.Using natural polymer or synthesis macromolecule electrospinning fibre structure group
Weaver's engineering support, can with the structure or even biological function of bionic extracellular matrix, sticking, break up and breeding beneficial to cell,
The regeneration and reparation of tissue are guided, becomes the research hotspot of tissue engineering bracket.Numerous studies report display, electro spinning nano fiber
Stent can provide preferable cell adhesion, propagation and differentiation microenvironment.
But Traditional DC electrospinning process still has certain technology bottle for efficiently preparing controllable three-dimensional structure
Neck.
Electrostatic spinning, which prepares fibrous framework, has following limitation:
1st, traditional electrostatic spinning be spinning solution or melt under the orientation of direct current field force, formed taylor cone,
The final surface tension that breaks through forms jet stream.Jet stream is drawn into nanofiber under the action of Coulomb force, and fiber is connect layer by layer
Ground collecting board attracts accumulation, forms the stent of film or approximate three-dimensional.But the fiber of stent is to carry out heap by charge attraction
Product, arrangement is close, the gap between fiber is too small, makes cell be difficult to grow into, can not construct gratifying three-dimensional tissue.Separately
On the one hand, traditional direct current electrospinning, electric field force direction is constant, when the viscosity of spinning solution or melt is larger, what jet stream needed
It is high to start voltage.
2nd, with the increase of film frame thickness, the electric field between nozzle and collecting board will gradually weaken, and cause film frame
Surface charges constantly accumulate, and because of band like charges, the fiber first deposited has an impact electric field distribution, and for subsequently penetrating
Miscarriage is raw to be repelled, so as to influence the duration of formation and the spinning of taylor cone, is reduced spinning efficiency, is ultimately resulted in electrospinning mistake
Journey terminates, and limits the thickness that can obtain stent(Usually micron order thickness), manufacture the electrospinning of the real meaning of big thickness
Three-dimensional structure is still more difficult.
3rd, when using the collector of given shape, fiber is toward the larger place deposition of electric field strength such as at tip, it is difficult to
Form three-dimensional structure.
4th, traditional sprinkler heads formula electrospinning inefficiency, single nozzle electrospinning yield usually only have 0.1-1g/h, it is difficult to realize big rule
Mould, efficient three-dimensional rack are manufactured.
High-speed air-blowing polymer solution carries out the extensive technology for preparing nanofiber(High-speed flow spinning technology), can be with
The more original electrostatic spinning speed of the preparation speed of fiber is set to improve more than 10 times, still, traditional gas is spun to be connect using closed more
Device or drum receiver are received, under action of high-speed airflow, recoil air-flow is easily produced, how influences the orientated deposition of fiber
Using the standby nano fiber scaffold with three-dimensional fluff structure of high speed gas spinning, the technique for still lacking stable versatility.And
And the fibre diameter of rotor spinning is larger(Micron order), diameter has a very wide distribution, prepares nanofiber and still suffer from technical bottleneck.
Laboratory research at present and the mainly electrostatic spinning of industrialized production and application(High direct voltage electrospinning), high voltage power supply
Generally use direct current(DC)Power supply is as high voltage power supply;Ac high-voltage electrospinning(AC electrospinning)Early in electrostatic spinning
The technology early stage of development has had researcher to use, but is not still furtherd investigate and developed so far.Exchange electrospinning
Production efficiency is of a relatively high.Moreover, exchange electrospinning need not be grounded or connect the collector of negative voltage, the flexibility ratio of collection mode
Higher.But directional collecting has given shape, the fibrous framework of structure more difficult, moreover, production efficiency also needs into one
Step improves.
CN1849418A is in charged electrode and in the space between electrode, being applied using air stream to nanofiber and being made
With promotion nanofiber is opened from charged electrode drift, is laid on the equipment for storage nano fiber before charged electrode.
A kind of nanofiber low pressure electric spinning equipment with auxiliary electrode described in CN102965743A, is arranged on collecting board using wind turbine
Side, makes fiber be deposited on collecting board by air-extraction function.CN103952780A collects side in electrostatic spinning and is provided with negative pressure suction
Air port, the micro nanometer fiber that the air-flow absorption produced using inlet scoop is ejected from spinneret needle end, makes it pinpoint or determine area
Domain is attached in the mesh base fabric before inlet scoop, by control the relative movement orbit of mesh base fabric and spinneret syringe needle and speed,
Form equally distributed web.Above-mentioned patent collects side by electrostatic spinning and introduces negative-pressure air-flow in favor of electrostatic spinning micro-nano
The collection of rice fiber, for improving fibre net homogeneity.But collect exchange pneumoelectric spinning nano fibre using negative pressure and prepare three-dimensional branch
There is not been reported for the scheme of frame.
In conclusion preparing, material ranges are extensive, fibre diameter is minimum, string diameter is evenly distributed, structure is fluffy, thickness pole
Greatly, the nanofiber three-dimensional rack of excellent in mechanical performance is still without general solution.
