Description
Technical field
The present invention relates to the electrostatic spinning technique field, relate in particular to a kind of electrostatic spinning apparatus and spinning process that from polymer solution, obtains nanofiber.
Background technology
Electrostatic spinning technique is applied to prepare the macromolecule monodimension nanometer material, can obtain the superfine fibre of diameter about 10～1000nm.Compare conventional fibre, new features such as high porosity that the remarkable decline of the diameter of nanofiber is brought and high-specific surface area make electrostatic spinning technique be studied widely and use in fields such as filtration, dressing, catalysis, sensing and tissue engineering brackets.
Common single needle head electrospinning device mainly is made of assemblies such as high voltage source, Spinning pumps, spinning head and gatherers.Under the high voltage electric field effect between spinning head and the gatherer, the shape that accumulates in the polymer solution droplets of spinning head mouth can become taper---and " taylor cone ", the impetus of electric field force is at the vertex of a cone.Along with the increase of electric field force, " taylor cone " comes to a point gradually, after cone-apex angle reaches a critical value, the metastable state of drop is destroyed, vertex of a cone solution surface molecule is subjected to enough big electric field force and overcomes surface tension, and polymer solution ejects from the vertex of a cone, forms injection stream.Electric field force stretches thousands of times to millions of times jet, and the diameter of jet is reduced to several microns to tens nanometers thereupon.Along with solvent evaporates, the fiber of gained finally is collected on metallic plate, wrapping head or other gatherers that is connected with ground wire with the form of nonwoven fabric.From applying electrostatic field, to forming nanofiber, the most difficult generation also is that a slowest step is to form " taylor cone ", and this is the rate determining step of spinning process.
In the electrostatic spinning of single needle head, spinning efficiency is very low, and (flow velocity of general spinning solution is 0.1～10mL/h), can't satisfy the requirement of industrial production to production efficiency.The prerequisite that electrostatic spinning technique can obtain industrial applications is to use new electrostatic spinning technique to improve unit interval spinning output.
CN101210352A, CN102776582A etc. disclose spininess head electrospinning process, can improve spinning efficiency effectively than the single needle head.The advantage of spininess head electrostatic spinning technique is that principle is simple, is the simple amplification to single needle head electrostatic spinning technique.But when improving spinning efficiency, also brought much more complicated problems, as: because electric field phase mutual interference between the syringe needle, the spinning Electric Field Distribution is irregular, and the electric field of syringe needle can be seriously undermined near the center, and each syringe needle nanofiber productive rate and fibre diameter difference are very big; Spininess head jet causes collector to obtain the fibre weight skewness because of the interference deflection of contiguous jet surface charge; In addition, syringe needle diameter Xiao Yi stops up, and is not easy cleaning, spininess head system maintenance cost height, and maintenance time is long, influences industrial production.
WO2005/024101A1 discloses a kind of columniform axial symmetry spinning electrode, its part immerses spinning solution, spinning electrode with electrode is formed electrostatic field, by this electrode around its symmetry axis rotation, spinning solution is fed in the electrostatic field continuously, reaches the purpose of continuous spinning.This invention has solved between the little and spininess head of syringe needle spinning amount the interactive problem of electric field mutually well.But, in actual production, unavoidable new problem mainly contains 3: 1, columniform electrode and to need could producing enough electric-field intensity up to the electrical potential difference more than the 80kV between the electrode, this requirement to the insulating Design processing of high voltage source performance requirement, spinning equipment is harsh; 2, columniform electrode needs the trough of the splendid attire q.s solution of an opening, make the part of electrode can immerse solution and the electrode rotation is not interfered, this set can make that solvent volatilizees in a large number, solution concentration changes, and solution concentration has determined pattern, structure, the performance of nanofiber, the steady quality of product during influence is produced continuously; 3, columniform electrode is in rotary course, exposed aerial surface area is very big, and during spinning, the thin electrolyte film that this part electrode surface adheres to, the solution that participate in to form taylor cone only accounts for the seldom part of liquid film, a large amount of solution in electric field, polarize and with sneak into after air contacts in the groove in the solution, we pass through big quantity research and find out, solution contacts and the erosion of polarized and water in air with electrode, can cause the aging of solution.This has reduced raw-material utilization rate widely in actual production, improve production cost.
WO2006/131081 has announced several cylindrical electrodes that have the tip of evagination, has solved first problem that cylindrical electrode is used to a certain extent, and promptly the tip of evagination can reduce the required electrical potential difference of the enough electrostatic fields of generation.But novel electrode does not only solve the easily problem that changes of the solution concentration brought of volatilization of solvent, does not solve the aging problem that is accelerated of solution yet; And electrode processing cost height, clean difficulty.
WO2009/010020 has announced a kind of brand-new spinning electrode, it selects for use the less wire of diameter as spinning electrode, and the invention before having overcome provides the dependence of high potential difference to equipment, has reduced the insulating Design processing request of equipment.It adopts the mode of spraying the polymer base fluid on electrode, can solve the problem that causes base fluid to wear out that cylindrical electrode runs into.Yet, have two aspect problems more outstanding:
On the one hand, raw material utilization ratio existing problems, promptly the solution of Pen Saing can not be used for spinning fully, and this is the certainty of this feed liquid way.
On the other hand, the feed liquid way that WO2009/010020 announced can't make all positions spinning simultaneously of a certain electrode at one time, this be because: enter the process that electric field finishes to spinning from solution, taylor cone to be formed into the beginning spinning be a longest step consuming time in the whole process.And described feed liquid way is with nozzle base fluid to be sprayed onto the other end along an end of wire electrode, also or with lead progressively pulls out from solution along its length.Obviously, which kind of feed liquid way no matter all exists diverse location on the spinning wire electrode that the problem of spinning can not take place simultaneously.
The technical process of this scheme reality is: a certain position has obtained new soln on the electrode; Through a little time interval, produced taylor cone in this position; Then this position just begins spinning, experiences this position spinning instability of a time interval again and need obtain new soln once more.Obviously, the problem of this feed liquid way is that beginning spinning, normally spinning, three processes of end spinning of whole one metal wire electrode can not take place on whole electrode the same time, and the discontinuous and unstable of this technology is very big problem aborning.
