Description
Technical field
The invention belongs to electrospinning micro nanometer fiber engineering field, relate to a kind of preparation method of nanofiber and prepared the technology of different micro nanometer fiber by Electrospun nozzle electrospinning technology.
Background technology
Electrostatic spinning technique is as one of method preparing micro nanometer fiber, and obtained fibre diameter can reach nanoscale.Electrospinning system mainly comprises following components: high-voltage power supply, shower nozzle syringe needle, ground connection collector.The key principle of electrostatic spinning applies high voltage for Polymer Solution, makes Polymer Solution form taylor cone at shower nozzle syringe needle mouth place.When voltage continues to increase, charged liquid will form injection stream at taylor cone tip place.In injection stream dropping process, along with the evaporation of solvent, fiber is formed, subsequently because the effect of electrostatic force falls on the collector.The macromolecule membrane collected forms the structure of random arrangement due to the motion out of order when fiber falls.The nonwoven fabric obtained by electricity spinning fibre, has that porosity is high, specific area is large, fiber fine degree and the advantage such as homogeneity is high, draw ratio is large.These prepare advantage is the characteristic that other preparation methods cannot obtain, and imparts electrospun fibers application prospect widely.Such as, can as the biological support in biomaterial, possess suitable mechanical strength, can induced cell growth and differentiation, can be degraded by human body absorbs and biocompatibility, has been widely used in tissue reparation and treatment.
At international electrostatic spinning as preparing in nanofiber process, low-yield is that the most significant defect also limits a large amount of production and the feasibility manufactured simultaneously.Therefore, some researchers launch research, to improve the productive rate of electrostatic spinning to multichannel electrostatic spinning apparatus.(the Srivastava such as Yasmin Srivastava, Y., et al., Electrospinning of hollow and core/sheath nanofibers using a microfluidic manifold. Microfluidics and Nanofluidics, 2007. 4 (3): p. 245-250) use semiconductor bulk equipment to prepare miniflow PDMS element, have devised the parallel electric spinning equipment with branch's MCA and coaxial nozzle, to obtain hollow nano fiber and composite nano fiber.This equipment successfully improves productive rate and obtains PVP and TiO
2mixture hollow fibre and PPy/PVP blended fiber, diameter is between 100 to 250nm.Yarin, A.L. (Yarin is waited, A.L. and E. Zussman, Upward needleless electrospinning of multiple nanofibers. Polymer, 2004. 45 (9): p. 2977-2980) by magnet and the obtained ferro-magnetic liquid of silicone oil mixing, permanent magnet is used to produce the formation of the spear protrusion of induced by magnetic field flow surface, then polymer solution is added in fluid, solution can stay the surface of magnet silicone oil mixture, high voltage is applied to mixture, uses conductive earthing metal collection fiber.In U.S. Patent application US6616435 B2, researcher uses single syringe pump to be delivered in 7 syringes by Polymer Solution or melting macromolecular material, apply voltage and carry out electrostatic spinning, simultaneously the collector of below with certain speed from while move collection to another side, form homogeneous fiber web, this Static Spinning is more stable, and effectively increases the output of electrostatic spinning fiber.These devices are all improved to some extent for the productive rate of electrostatic spinning.Too low through Electrospun productive rate for fear of current single needle, needing arranges in pairs or groups by several syringe pumps and syringe needle is improved, or utilize the multichannel electrostatic spinning apparatus of micro-nano processing preparation, larger installations complexity and the numerous Suo of manufacturing equipment Ang Expensive, prepare the industrialized certain obstruction realizing being formed of micro nanometer fiber for electrospinning.
On the other hand, electrostatic spinning can form continuous fibers by polymer solution or melt are applied electric field under electric field action, regulation and control to obtain electrostatic spinning diameter be that a key technology also have impact on Application Areas.The control methods of current diameter can apply voltage, spinning distance by changing, spinning liquid concentration, injection flow and controlling the regulation and control that the modes such as electric current obtain spinning diameter.For reaching effectively change side's filament diameter in spinning operation, or obtain the application of different spinning diameter distribution, must fixing via above-mentioned parameter (voltage, spinning distance, spin liquid concentration, injection flow and control electric current) after, change the different spinning diameter of a gain of parameter wherein, therefore effectively cannot obtain the spinning that synchronous (simultaneously) possesses different-diameter.For fear of fiber the needs collocation regulation and control parameter change preparing different-diameter distribution at present, and the fiber of different-diameter cannot be prepared, the spinning while of forming different-diameter simultaneously, prepared by certain obstruction that the industrialized application of micro nanometer fiber also formed for electrospinning.
