Description
Technical field
The present invention is used for nano fiber scaffold technical field, particularly relates to the centrifugal pneumoelectric device for spinning of a kind of negative pressure array.
Background technology
Electrospinning prepares the effective ways of nanofiber.Fibre diameter usually between tens nanometer between several microns, with the adjoining dimensions of the fibrous framework such as collagen in extracellular matrix.Natural polymer or synthesis macromolecule electrospinning fibre is adopted to build tissue engineering bracket, can the structure of bionic extracellular matrix and even biological function, be beneficial to the sticking of cell, Differentiation and proliferation, the renewable reservoir of transmitting tissue, becomes the study hotspot of tissue engineering bracket.The display of large quantity research report, electro spinning nano fiber support can provide desirable cell adhesion, propagation and differentiation microenvironment.
But Traditional DC electrospinning process is used for the controlled three-dimensional structure of efficient preparation and still there is certain technical bottleneck.
Electrostatic spinning is prepared fibrous framework and is had following limitation:
1, traditional electrostatic spinning be spinning solution or melt under the orientation of direct current field force, form taylor cone, the final surface tension that breaks through forms jet.Jet is drawn into nanofiber under the effect of Coulomb force, and fiber is grounded collecting board layer by layer and attracts to pile up, and forms the support of film or approximate three-dimensional.But the fiber of support piles up by charge attraction, the space of arrangement closely, between fiber is too small, makes cell be difficult to grow into, cannot construct gratifying three-dimensional tissue.On the other hand, traditional direct current electrospinning, electric field force direction is constant, and when the viscosity of spinning solution or melt is larger, the starting resistor that jet needs is high.
2, along with film frame thickness increases, electric field between shower nozzle and collecting board will weaken gradually, film frame surface charges is caused constantly to accumulate, because of band like charges, the fiber first deposited has an impact to Electric Field Distribution, and subsequent shot is produced and repels, thus affect the formation of taylor cone and the duration of spinning, reduce spinning efficiency, finally cause electrospinning procedure ends, limit the thickness (being generally micron order thickness) that can obtain support, the electrospinning three-dimensional structure manufacturing the real meaning of heavy thickness is still comparatively difficult.
3, when adopting the collector of given shape, fiber deposits toward the place that the electric-field intensity such as most advanced and sophisticated place are larger, is difficult to form three-dimensional structure.
4, traditional sprinkler heads formula electrospinning inefficiency, single jet output only has 0.1-1g/h usually, is difficult to realize three-dimensional rack in large-scale, high-efficiency and manufactures.
High-speed air-blowing polymer solution prepares the technology (high velocity air spinning technology) of nanofiber on a large scale, the more original electrostatic spinning speed of the preparation speed of fiber can be made to improve more than 10 times, but, tradition gas spins the closed receiver of many employings or drum receiver, under action of high-speed airflow, easily produce recoil air-flow, affect the orientated deposition of fiber, how to adopt high speed gas to spin the nano fiber scaffold of three-dimensional fluff structure of getting everything ready, still lack the technique of stable versatility.Further, the fibre diameter comparatively large (micron order) of rotor spinning, diameter has a very wide distribution, and prepares nanofiber and still there is technical bottleneck.
The mainly electrostatic spinning (high direct voltage electrospinning) of current laboratory research and suitability for industrialized production application, high voltage source generally adopts direct current (DC) power supply as high voltage source; Ac high-voltage electrospinning (ACelectrospinning) has had researcher to adopt as far back as the electrostatic spinning technique early stage of development, but is not still furtherd investigate so far and develop.Exchange electrospinning production efficiency relatively high.And exchanging electrospinning does not need ground connection or connects the collector of negative voltage, and the flexibility ratio of collection mode is higher.But, directional collecting have given shape, structure fibrous framework comparatively difficult, and production efficiency also needs to be improved further.
CN1849418A, at charged electrode with in the space between electrode, utilizes air stream to nanofiber applying effect, promote nanofiber from charged electrode drift open, laid before charged electrode for the equipment of storage nano fiber.A kind of nanofiber low tension spinning equipment with auxiliary electrode described in CN102965743A, adopts blower fan to be located at above collecting board, makes fiber laydown on collecting board by air-extraction function.CN103952780A collects side at electrostatic spinning and is provided with negative-pressure air-suction mouth, the micro nanometer fiber that the air-flow absorption utilizing inlet scoop to produce ejects from spray silk needle end, make it fix a point or determine region be attached to inlet scoop before mesh base cloth on, by control mesh base cloth and spray silk syringe needle relative movement orbit and speed, form equally distributed fiber web.Above-mentioned patent is collected side by electrostatic spinning and is introduced the collection that negative-pressure air-flow is beneficial to electrostatic spinning micro nanometer fiber, for improving fibre net homogeneity.But there is not been reported to utilize negative pressure to collect to exchange pneumoelectric spinning nano fibre to prepare the scheme of three-dimensional rack.
In sum, preparation material ranges is extensive, fibre diameter is minimum, string diameter is evenly distributed, structure is fluffy, thickness is very big, the nanofiber three-dimensional rack of excellent in mechanical performance does not still have general solution.
