Figs. 1 to 3 are diagrams for explaining electrospinning results of an electrospinning apparatus including one to three probes in a probe, respectively. Fig.
The electrospinning device to be described below includes a probe, a probe coupled to the probe, a solution reservoir for supplying a polymer material for electrospinning to the probe, a power supply for supplying a voltage required for the electrospinning, And a collecting part for collecting the fibers radiated as the probe sprays the polymer material.
1 (a) showing a structure of a probe including one probe, and FIG. 1 (b) showing a result of performing electrospinning using the probe. FIG. 1 c) shows a screen of the result of electrospinning using a probe including the probe, which is observed with a microscope.
As shown in FIG. 1 (b), when electrospinning is performed using a probe (FIG. 1 (a)) including one probe, it can be confirmed that the radiation is concentrated in a specific region only, As shown in FIG. 1 (c), when observed under a microscope, the morphologies of the spun fibers are not aggregated but collected in a separated state.
Next, referring to FIG. 2, a structure of a probe including two probes is shown in FIG. 2 (a), and FIG. 2 (b) is a result of performing electrospinning using the probe. FIG. 2 (c) is a view of a result of electrospinning using a probe including the two probes, which is observed with a microscope.
Here, referring to FIG. 2 (b), when compared with FIG. 2 (b) showing the result of electrospinning using a probe including one probe, the radiation is not concentrated in a specific region, It can be confirmed that it is divided into a plurality of regions, and in addition, it can be confirmed that some lumps are included in the radiated region. 2 (c), it can be confirmed that the morphologies of the radiated fibers are collected in a state where they are partially gathered with each other. Thus, in a form different from that shown in FIG. 1 (c) You can see what is being captured.
3 (a) shows the structure of a probe including three probes, FIG. 3 (b) shows a result of performing electrospinning using the probe, and FIG. 3 3 (c) shows the result of the electrospinning using a probe including the three probes, which is observed with a microscope.
Referring to FIG. 3 (b), when compared with the result of electrospinning using a probe including one or two probes as shown in FIGS. 1 (b) and 2 (b) (C) or FIG. 2 (c), in which the morphology of the fiber has one characteristic and is consistently collected, (c), it can be confirmed that some of the fibers are collected separately, and they are collected even in a state where they are bundled together. Thus, it can be confirmed that the fibers are collected in various forms inconsistently.
1 through 3, the results of the electrospinning using a probe including one to three probes showed that the smaller the number of probes in the probe, the narrower the emission was And furthermore, it can be confirmed that the more the number of probes in the probe, the more the collection of fibers becomes clumped or distorted.
The reason why the shape of the fibers is changed according to the number of probes included in the probes is that the electrical interaction between the electric fields induced in each of the probes causes the efficiency of electrospinning to deteriorate.
More specifically, when one to three probes are included in the probe, it is general that the probes are arranged in the forward direction. Accordingly, when an electric current for electrospinning flows to the probe bar made of a conductive material and an electric field is induced for each probe, the electric fields induced in the respective probes cause electric interaction and affect each other. And only the probe at both ends of the probe will emit radiation, affecting the electrospinning performed by each probe.
Therefore, if the number of probes included in one probe increases, the distance between the probes in the probe must be reduced, and the distance between the probes becomes closer to each other. As a result, if a large number of probes are included in one of the probes, there is a problem that the efficiency of electrospinning by the probes is greatly reduced because the influence due to the electrical interaction between the probes is very large. .
Accordingly, in order to solve the above-mentioned problem, the present invention is to describe a probe for use in an electric furnace with a probe attached spirally so as to reduce the electrical interaction between the probes and continuously produce a large amount of nanofibers. Hereinafter, a detailed description will be given with reference to FIG. 4 and FIG.
FIG. 4 is a view for explaining a continuous process electrospinning apparatus using a spiral probe according to an embodiment of the present invention. FIG. 5 is a cross-sectional view of a probe of a continuous process electrospinning apparatus using a spiral probe according to an embodiment of the present invention. Fig.

(5, 6).
4, the continuous process electrospinning apparatus using the spiral probe according to an embodiment of the present invention may further include other configurations other than the configurations described above, and some of the configurations described above may be omitted .
Referring again to FIG. 4, the probe 1 may comprise one or more probes. Hereinafter, for convenience of explanation, it is assumed that the probe includes a plurality of
At this time, the probe bar 1 may have a part of the structure supported on the
The probe 1 may include a plurality of probes. The probes may be formed by injecting the high-character material drawn from the
In addition, in order to solve the above-mentioned problems, the continuous process electrospinning apparatus using the spiral probe according to an embodiment of the present invention has a configuration in which each of the
In this way, when the predetermined number of the
Also, in the case of conventional probes or conventional needless electrospinning, it is common that the material of the probe or rotating rod is made of a conductor such as metal, so that the voltage of the probe or rotating rod There is a problem that efficiency of electrospinning is somewhat deteriorated due to loss.
However, in the case of the continuous process electrospinning apparatus using the spiral probe according to an embodiment of the present invention, the probe may be made of non-conductive material, and each of the
At this time, the
When the plurality of
Referring again to FIG. 4, the probe may perform electrospinning by spraying the high-character material drawn from the
At this time, the probe 1 can rotate 360 degrees at a predetermined speed, and each of the probes of the multiple probes included in the probe 1 while the probe is rotating 360 degrees is rotated at a predetermined injection point The liquid type polymer material is injected every moment it is positioned to perform the electrospinning.
According to an embodiment of the present invention, the predetermined injection point may be inclined by a predetermined angle range with respect to a vertical direction of the probe, and the predetermined angle range may be a vertical direction of the probe It can be from 45 degrees to 60 degrees as a standard.
At this time, the liquid type polymer material ejected from the predetermined number of ejection points from the multiple number of probes is transferred to the
For example, when each of the plurality of probes injects the polymer material in the form of liquid to perform the electrospinning, the injection point is in an angle range of 45 degrees with respect to the vertical direction of the probe, May be positioned in an angular range of 45 degrees with respect to a vertical direction of the probe, which is an angle range in which the injection is performed.
That is, in the case of a conventional needleless electrospinning device, since the direction of electrospinning is vertical (from top to bottom), electrospinning is performed using a high voltage of about 30 to 60 kV (kilovolts) And thus there is a problem that a high voltage is required for electrospinning.
However, in the case of the electrospinning device according to an embodiment of the present invention, at a specific point inclined by 45 to 60 degrees with respect to the vertical direction of the probe, The electrospinning can be performed at a lower voltage (about 15 to 18 kV) due to the centrifugal force induced by the rotation of the probe bar 1, since the liquid type polymer material is injected to perform the electrospinning. Therefore, it becomes possible to perform electrospinning at a relatively low voltage, so that a larger amount of nanofibers can be produced at the same voltage, thereby increasing the efficiency of the electrospinning process and reducing the cost of the electrospinning process There is an effect that can be done.
6 is a view for explaining electrospinning results of a continuous process electrospinning apparatus using a spiral probe according to an embodiment of the present invention.
6 (a), poly (methyl methacrylate) (PMMA) polymer produced according to electrospinning performed by using a probe having a plurality of probes arranged in a straight line in a positive direction FIG. 6 (b) is a graph showing the results of a microscopic observation of a plurality of probes according to an embodiment of the present invention, and FIG. 6 And a microscopic observation of the resulting polymethacrylate (PMMA) polymer is shown.
The PMMA polymer shown in FIG. 6 (a) and the PMMA polymer shown in FIG. 6 (b) are different from each other only in the arrangement of the probe included in the probe, 10% THF (tetrahydrofuran) solvent) are assumed to be the same.
6 (a), when a plurality of probes are arranged in a line in a positive direction and a current for electrospinning flows through the probe, the electric fields induced in the respective probes are electrically The fibers shown in Fig. 6 (a) are formed to have a coherent or distorted shape because they interact with each other and affect each other and influence the electrospinning performed by each probe according to such influence .

As described above, when a plurality of the probes are spaced apart from each other in a spiral manner, the electrical interaction between the probes can be reduced, And the quality of the fiber can be further improved.
It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
