Background technology
Along with the development of nanometer technology in recent years, electrostatic spinning has become the important method of preparing nanofiber and has received much concern.Method of electrostatic spinning is widely used, from industrial synthetic polymer to cellulose, the various raw material such as ossein, protein, DNA complex can carry out spinning, and antibiotics, nano particle etc. can be added in spinning process, prepare various functional fiber.
Traditional electrostatic spinning technique is one and prepares the most widely used technology of nanofiber, it utilizes HV generator to produce several kilovolts even high-pressure electrostatic of tens kilovolts and apply pressure in polymer solution or melt, makes needle tip drop deformation form taylor cone.When electric field force reaches critical value, can overcome surface tension, jetting stream, jet reels in the electric field, and bending, final curing is on dash receiver.But, in traditional electrostatic spinning, the electrostatic spinning output of needle point spray nozzle type is little, though adopt Multi-tip spray nozzle type electrostatic spinning apparatus to improve output to a certain extent, but because the spacing between spinning head is little, easy generation electrostatic interference, make spinning process unstable, and some spinning heads does not carry out spinning.Low-yield, homogeneity difference is that Electrospun can not the main cause of large-scale industrial production or application.Document [1] ([1] OODosunmu, GGChase, WKataphinan, et al.Nanotechnology.2006; 11:1123-7.) prepared nanofiber with antipriming pipe as shower nozzle, output improves about 250 times than traditional electrostatic spinning in this way.But the preparation process of this method is unstable, and the problem of antipriming pipe blocking is also difficult to solve.Chinese patent CN200810153891.9 reports a kind of non-woven not electric spinning equipment in batches, the metal roller that this device adopts the circumferential outer surface being immersed in polymer solution to be cast with tapered thread is injector head, spinning is carried out to replace traditional needle point shower nozzle, though output significantly improves, but it exists the high shortcoming of injection electric threshold value, and the nanofiber containing two kinds of materials can not be spun simultaneously.
Summary of the invention
The purpose of this utility model is to provide and can improves electrospinning device productive rate and spin fiber membrane caliper uniformity, without the linear shower nozzle of a kind of electrostatic spinning of shower nozzle blocking.
The utility model is provided with conductive filament support, conductive filament, solution feed mechanism; Conductive filament and conductive filament support are connected, and solution feed mechanism is for being evenly coated in conductive filament by spinning solution.
