Background technology
Traditional electrospinning device generally includes hollow needle-like spinneret, is used to carry transmission device, gatherer and the high-voltage generator of spinning solution.High voltage puts on spinneret and gatherer (also being " to electrode ") usually.In the electrostatic spinning process, high voltage puts on spinning solution through spinneret, also between spinneret and receiving system, forms high voltage electric field simultaneously.Because the effect of high voltage electric field, spinning solution is drafted one-tenth cone structure (also being " taylor cone ") in position, spinneret top.When electric field force is high to a certain degree, spinning solution overcomes self capillary effect, ejects from the top of taylor cone, forms " jet ".Charged jet receives the high voltage electric field effect immediately, and drawing-off attenuates rapidly.The repulsive force that forms between the inner identical charges of jet also can quicken jet drawing-off and swing.In this simultaneously, the volatilization of solvent causes jet to solidify, and finally is deposited on and is similar to non-weaving cloth shape nanofiber network to forming on the electrode gatherer.
There is pin electrostatic spinning nano fiber technology of preparing that very limited production capacity can only be provided.Because each spinneret per hour can only produce 300 milligrams nanofiber at most.Because the high-voltage potential enrichment, when voltage was higher than 30,000 volts, the top of needle-like spinneret can form " glow discharge ", thereby stopped spinning process.Just because of this, there is the pin electrostatic spinning nano fiber to prepare voltage less than 30,000 volts.The nanofiber of preparation is thick and inhomogeneous under low operating voltage.

At this electrostatic spinning system, the formation of nanofiber is depended near the spinneret to a great extent and whole electricity spins regional electric-field intensity and Electric Field Distribution.Because electric field is far smaller than the cylinder two ends in the intensity of cylinder mid portion, when voltage subcritical value, the mid portion of cylinder loses the spinning ability.Have only the two ends of cylinder can spin nanofiber.Even operating voltage is higher than critical value, the diameter of the nanofiber that produces at different cylinders position also has very big difference.Therefore, the nanofiber fineness of preparation is very inhomogeneous.Necessary through improving the quality that spinneret improves nanofiber.

The specific embodiment
Utility model provides a kind of new screw type needleless static nanofiber production equipment at present, also is called static spiral device for spinning, is mainly used in various viscous liquids are processed into nanofiber under electrostatic field.The nanofiber generating means (also being " spinneret ") that any amount helical blade is formed is contained by one or one group in the core of this nanofiber production equipment.Coaxial helical blade nanofiber generator comprises spinning helical blade and a rotating driving shaft, and wherein helical blade mainly is to be fixed on this driving shaft.Blade compares greater than 1: 3 with the diameter of driving shaft, is more preferably greater than 1: 5, more preferably greater than 1: 10.
Helical blade is mainly used in the edge that electrostatic field is concentrated on blade, and reduces or eliminate the influence to electrostatic field of blade shape and size.Such device can make high electric field evenly and the concentrated area is distributed in the fiber of blade and forms region surface.When electricity spun, when electrostatic field intensity was enough to that spinning solution pulled into " taylor cone ", the jet that forms nanofiber resulted from the blade edge zone.When using a plurality of helical blade, can be through optimizing the distance reduction between the blade or avoiding the electric field of blades adjacent to disturb fully.Compare with drum-shape needleless electrostatic spinning head, such device can produce thinner and uniform nanofiber.The helical blade of spinneret can be made up of an independent blade or a plurality of blade.When being used for extensive nanofiber and producing; The helical blade of spinneret preferably comprises one group of blade; And along central shaft to being scattered in helical structure; Because a plurality of blades can provide bigger nanofiber to produce area, and distribute the vertically nanofiber that makes production of blade is deposited on the surface of passive electrode equably.
Helical blade can be designed to Any shape.Like the cross section can be circular, ellipse, rectangle, taper, prism-type or other.Helical blade can distribute around central shaft.The radius of blade can be between 5 to 1000 millimeters.The thickness of blade can be between 0.5 to 200 millimeter, preferably between 0.7 to 50 millimeter.When using one group of blade, these blades can relatively independently be arranged.The length of whole spinneret can be between 20 to 6000 millimeters.
When using one group of identical blade, the electric-field intensity of the two ends blade of the helical blade of spinneret often is higher than the blade of mid portion.When the radius of two ends blade hour, the electric field that helical blade produces vertically can be distributed in to equal strength each blade.Therefore the blade preferred design at two ends becomes by less radius.
Between blade and the blade certain interval to be arranged, to reduce influencing each other between the blade.Distance between the blade vertically, vane thickness, diameter and structure can be adjusted.Distance between the adjacent blades of helical blade is preferably between 5 to 800 millimeters.
Helical blade can be any material, and conduction or insulating materials all can.Can be metallic copper, iron, or aluminium etc., also can be engineering plastics, resin, pottery, timber or composite.Major requirement to the helical blade material is in spinning solution, to dissolve or to degrade.
Helical blade can be a hollow structure, has passage to be connected with hollow driving shaft, with the transmission spinning solution.In this case, blade surface should have perforate.Spinning solution can arrive the blade surface that generates fiber through blade and driving shaft internal transmission.
The needleless static nanofiber production equipment of in electric field, from viscous liquid (that is, " spinning solution "), producing nanofiber that the utility model provided also is called static spiral device for spinning, and it mainly comprises like the lower part:
Aforesaid helical blade nanofiber generator (i.e. " helical blade spinneret ");
With the nanofiber generating means separated by a distance to electrode nanofiber receiver (also being called " to the electrode gatherer ");
The dress storage is used for the container of the viscous liquid (spinning solution) of spinning;
And high-voltage generating device.
The electrode of high-voltage generator is connected to the helical blade spinneret and to the electrode gatherer, to produce high potential difference.
Nanofiber results from the spinning solution that is covered in helical blade spinneret surface.High pressure generator makes helical blade nanofiber generator and electrode nanofiber gatherer is produced high potential difference.When the spinning solution surface and the electrical potential difference that forms between to the electrode gatherer when being higher than certain numerical value (as 30,000 volts), jet will produce from blade surface, and finally forms nanofiber.The critical electric field strength that produces nanofiber is relevant with several factors, comprises the helical blade spinneret and to the shape and the size of electrode gatherer, the physicochemical property of distance between them (also be " spinning distance ", or " collection apart from ") and spinning solution.In general, the generation of nanofiber needs at least 4 ten thousand volts of high voltages.In most cases more preferably greater than 60,000 volts.
The helical blade spinneret and to distance between the electrode gatherer can influence the quality of electric-field intensity and nanofiber.Certainly, influence also can be from the helical blade spinneret with to the shape of electrode gatherer and the character of spinning solution.In general, to the axially parallel of electrode nanofiber gatherer and helical blade nanofiber generator.Length and width to the length of electrode nanofiber gatherer and said helical blade nanofiber generator are suitable.Spinneret be 100 to 600 millimeters to the electrode standoff distance.
Spinning solution can be any liquid that can generate nanofiber, like polymer solution, and collosol and gel, particle suspension liquid, or the polymeric liquid of fusion.In most cases, spinning solution is by at least a polymer and a kind of volatile solvent composition.High molecular polymer, like synthetic high polymer, natural polymer and large biological molecule, thermoplastic polymer or living polymer all can.The use of solvent depends primarily on the kind and the character of polymer.They can be volatile solvents, comprise water, ethanol, chloroform, dimethyl formamide etc.Spin curing and the shaping that the volatilization of solvent in the process helps nanofiber at electricity.
A lot of methods can be used for spinning solution is loaded into the surface of helical blade spinneret.For example, the helical blade nanofiber generator of static spiral device for spinning is immersed in the viscous liquid, and helical blade nanofiber generator is designed to and can rotates along central shaft, can load viscous liquid from the teeth outwards like this.The rotation of blade can make spinning solution cover the whole blade surface.In this case, the surface of helical blade nanofiber generator has at least a place to link to each other with the interior viscous liquid of liquid container.To the electrode gatherer preferably be in the helical blade spinneret directly over, and parallel with the driving shaft of helical blade spinneret.When electricity spun, nanofiber spun from the blade edge top surface, and deposited on the electrode receiver.
Spinning solution also can be loaded into the surface of blade from the inside of helical blade.Helical blade is a hollow structure in this case, and has passage to link to each other with outside reservoir.The perforate of blade surface makes spinning solution be loaded into the fiber generation area of spinneret equably.In this case, helical blade spinneret below liquid bath is mainly used in and collects excessive spinning solution.
Also can use various structure to the electrode gatherer.Except fixing board joint receiving apparatus, the cylinder of rotation, or be similar to the continuously trapping system of conveyer belt and can be more effectively collect nanofiber is continuous.In some cases, solidify for the ease of solvent evaporates and nanofiber, to the electrode gatherer can use porous network shape structure to electrode fiber receiving surface, and with the cross-ventilation and the solvent diffuse of the dry air acceleration collecting zone of uniform temperature.
The nanofiber that static spiral device for spinning is produced is non-weaving cloth or the nano-fiber film that aligns is arranged.
In order to prepare nanofiber more on a large scale, needleless nanofiber spinning equipment can comprise the multi-detector blade spinneret that is parallel to each other.In this case, the multi-detector blade can a shared big reservoir, perhaps adopts a plurality of independent device for storing liquid.For fear of the influence of contiguous helical blade, distance between row and row is much in 20 millimeters, preferably greater than 50 millimeters.
Specify instance below in conjunction with accompanying drawing according to the static spiral device for spinning of the utility model.
Of Fig. 1, static spiral device for spinning 1 is by helical blade spinneret 10, and to electrode gatherer 11, spinning solution storage tank 12 and high-voltage power supply 13 are formed.Spinneret 10 comprises driving shaft 101 and helical blade 102.The electrode of high-voltage generator is connected in spinneret 10 via electrode connecting line 14a and 14b respectively and to electrode gatherer 11.Spinning solution is stored in storage tank 12 inside.The liquid level of spinning solution has certain being connected with blade 102.When blade slowly rotates (as, rotating speed 40rpm) because the wetting action of liquid, spinning solution can be coated the surface of helical blade equably.
Fig. 2 has shown more detailed helical blade spinneret structure.The metal spiral blade is vertically along stretching.When helical blade contains the blade more than three, littler than the radius of intermediate blade near the blade radius at two ends.Helical blade partly is soaked in the spinning solution.
As typical example, said apparatus is used to prepare the polyacrylonitrile nano fiber.Spinning solution is polyacrylonitrile (PAN)-dimethyl formamide (DMF) solution of 9%.Spin in the process at static, nanofiber is produced in the fringe region of blade surface.
As a comparison, traditional pin electro-spinning equipment that has also is used to process identical spinning solution.
Experimental result:
Spin in the process at electricity, because the rotation of helical blade, viscosity PAN solution can load on blade surface equably.When applying high voltage electric field, a large amount of jets are formed at the blade edge surface.Minimum applied voltage is 60,000 volts.The nanofiber that needleless device is produced very evenly.All about 150 nanometers of average diameter.And the average diameter that has pin to spin the fiber that comes is greater than 200 nanometers.Have pin to spin to compare with traditional, it is much thin that the nanofiber that this needleless electrospinning device is produced is wanted, and the diameter Distribution of fiber is also more even.Wherein, a kind of operating condition is as follows: operating voltage: 60,000 volts; Collect distance: 150 millimeters; Spinning solution: polyacrylonitrile-dimethyl formamide solution of 9%.Another kind of operating condition is as follows: operating voltage=20,000 volt; Collect distance: 150 millimeters; Spinning solution: polyacrylonitrile-dimethyl formamide solution of 9%.
Fig. 3 and Fig. 4 show the distribution situation of electric-field intensity.Be not difficult to find out that high electric field is mainly concentrated the apex zone that is formed at blade edge.And electric-field intensity is very big.The area coincidence that in fact this zone produces with fiber.That is to say that nanofiber mainly is formed at the electric field rich region of blade surface.Though traditional pin electrostatic spinning apparatus that has can be the enrichment electric field at the end of spinneret also, it is much little that the numerical value of electric-field intensity is wanted.
For a length is 20 centimetres static spiral device for spinning, and the production capacity of nanofiber is 20 grams per hour.When the length of device is one meter, and when using the identical spiral device for spinning of 10 rows, the living ability of nanofiber is per hour 1 kilogram.By contrast, for tradition the pin electro-spinning equipment is arranged, singular needle apparatus needs 20 * 10 centimetres squares area, and its nanofiber production capacity is no more than per hour 0.3 gram.Spininess static spinning equipment is about 100 spinning pins in 1 meter square, and the production capacity of its nanofiber is for per hour 30 restraining.
Further experiment proves that also the size of blade is very little to the influence of electric field and fibre diameter, but very big to the speed of production influence.
