[Prior Art] Electrospinning technology is one of the nanofibers manufacturing technologies. The principle is to use the electric field driving force between the positive and negative electrodes to overcome the surface tension and viscosity of the electrospun liquid of the polymer. The dope forms a fine fiber. In the prior art, the electrospinning liquid which is charged with a high voltage to the electrospun liquid of the polymer by the emitter electrode is ejected through a nozzle (Spinneret), and is mutually repelled by the same electric property, and is dispersed into a filament shape. The electrospun liquid is then drawn to the collector via the attraction between the positive and negative electrodes. After the solvent in the electrospinning solution is volatilized, extremely fine electrospinning fibers (Electrostatic spinning fibers) can be obtained. Compared with the conventional spinning method, the fibers spun by the electrospinning technology are extremely fine, and the woven fabric has a high porosity and a large surface area, and thus is favored. However, in the conventional electrospinning technology, most of the charged electrospinning liquid is subjected to an electrospinning process after dissolving the polymer in a solvent, and for a polymer which cannot be dissolved at a normal temperature, it cannot be carried out by a general room temperature electrospinning apparatus. Electrospinning. In the electrospinning process using a crystalline polymer composite, the nozzle and the solution must be in a high temperature environment to avoid clogging of the nozzle. . Therefore, in the electrospinning process using a crystalline polymer composite material which cannot be dissolved at room temperature, how to avoid the clogging caused by the decrease of the solution temperature in the south temperature electrospinning process becomes an important Question. 201209233 SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a high temperature electrospinning apparatus for solving the problem of nozzle clogging. According to an embodiment of the invention, a high temperature electrospinning apparatus is provided, comprising a nozzle having a connected spinning channel and an injection port, a spinning supply unit connected to the spinning channel to provide a polymer solution spinning, and a laser A generating device, a spinning collection unit, and a high voltage electric generating unit. A laser generating device is provided to provide a laser beam directed at the heating nozzle to maintain the temperature of the nozzle. The high-voltage generating unit is respectively connected to the nozzle and the spinning collecting unit to apply a voltage difference between the nozzle and the spinning collecting unit, wherein the polymer solution spinning material is ejected by the ejection port to form an electrospinning and then collected by the spinning collecting unit. . The nozzle preferably has a dark surface. The high-temperature electrospinning apparatus may further include a convex lens disposed between the laser generating device and the nozzle. The high temperature electrospinning apparatus may further comprise a heating jacket which is attached to the spinning supply unit. The electrospinning apparatus may further comprise a solvent vapor supply unit having a solvent vapor outlet, the solvent vapor outlet being disposed adjacent to the injection port. The solvent vapor supply unit comprises a ring cover, the ring cover is sleeved on the nozzle, the gap between the ring cover and the nozzle is provided, and the solvent vapor outlet is connected to the ring cover. The ring cover has a ring cover opening, and the opening direction of the ring cover is the same as the injection port. The ring cover has a laser passage for the laser beam to pass through. The local temperature electrospinning apparatus may further include an infrared heater, and the infrared heater is disposed on one side of the nozzle. Another aspect of the present invention is a high temperature electrospinning method comprising: providing a polymer solution spinning to a nozzle, and then using a laser generating device to generate a laser beam directed to the heating nozzle and adjusting the power of the infrared heater, thereby further Control the electrospinning process ambient temperature, and supply voltage difference to the nozzle and spinning 201209233 wire collection unit, so that the polymer solution spinning material is ejected through the nozzle to form electrospinning and then collected by the spinning collection unit. The high-temperature electrospinning device utilizes a laser beam to perform directivity heating of the nozzle, and the non-contact heating method can effectively solve the problem that the temperature of the tiny needle is difficult to maintain, and the polymer solution is solidified to block the nozzle. The situation. For a crystalline polymer that cannot be dissolved at room temperature, electrospinning can be carried out using such equipment and methods. The present invention will be clearly described in the following drawings and detailed description, and those skilled in the art will be able to change the teachings of the present invention. And modifications may be made without departing from the spirit and scope of the invention. Referring to Fig. 1, there is shown a schematic view of a first embodiment of the high temperature electrospinning apparatus of the present invention. The high temperature electrospinning apparatus 100 includes a nozzle 110, a spun supply unit 120 connected to the nozzle 110, a laser generating device 130, a spinning collecting unit 140, and a high voltage electric generating unit 150. The nozzle 110 includes a spinning flow path 112 and an injection port 114. The spun supply unit 120 is connected to the spinning flow path 112 of the nozzle 110 and provides a polymer solution spinning. The laser generating device 130 provides a laser beam that is directed to the heating nozzle 110 to maintain the temperature of the nozzle 110. The high-voltage generating unit 150 connects the nozzle 110 and the spinning collecting unit 140, respectively, so that the nozzle 110 and the spinning collecting unit 140 are respectively electrically different. The high voltage electricity generating unit 150 applies a voltage difference between the nozzle 110 and the spinning collection unit 140. 201209233 The polymer solution spinning material provided by the spinning supply unit 120 is ejected through the ejection opening 114 of the nozzle 110, and the electrospun electrospinning is carried out after the electrospinning of the polymer solution with the same electrical properties is mutually repelled to form an electrospinning. The filaments are drawn to a spinning collection unit 140 that is electrically different. The spinning collection unit 140 may include a receiving electrode made of a metal material, a conveying belt passing through the receiving electrode, a plurality of rotating members for rotating the conveying belt, and a driving motor for driving the rotating member. The receiving electrode and the nozzle 110 are differentially charged to collect electrospinning. The conveyor belt of the spinning collection unit 140 may further comprise a woven fabric which may be combined with electrospinning to form a composite woven fabric. Alternatively, the spinning collection unit 140 may be a flat electrode, a zigzag electrode or the like. Since the body of the nozzle 110 is actively small, and the shape of the nozzle 110 is similar to a needle shape, it is extremely easy to dissipate heat, and the temperature of the polymer solution spinning therein is suddenly lowered to block the ejection opening 114. Further, the nozzles 110 having a small positive body need to be further connected to the high-voltage power generating unit 150, so that it is difficult to additionally connect the heating means for the nozzles 110. In view of this, the high temperature electrospinning apparatus 100 of the present invention heats the nozzle 110 using the laser generating device 130. Since the diameter of the laser beam is small, the laser output power is easy to adjust, and has a straight forward characteristic, the high temperature electrospinning apparatus 100 can perform non-contact fixed-point heating of the nozzle 110 through the laser generating device 130. As a result, the temperature of the nozzle 110 can be effectively maintained, which solves the problem that the temperature of the polymer solution spinning material suddenly drops after flowing through the spinning channel 112, and the ejection port 114 is blocked. Referring to Fig. 2, there is shown a schematic view of a second embodiment of the high temperature electrospinning apparatus of the present invention. The high temperature electrospinning apparatus 100 includes a nozzle 110, a spun supply unit 120 connected to the nozzle 110, a laser generating device 130, a 201209233 spinning collection unit 140, and a high voltage electric generating unit 150. The spinning supply unit 120 is connected to the nozzle 110 and provides a polymer solution spinning. The laser generating device 130 provides a laser beam that is directed toward the heating nozzle 110 to maintain the temperature of the nozzle 110. The high-voltage generating unit 150 connects the nozzle 110 and the spinning collecting unit 140, respectively, so that the nozzle 110 and the spinning collecting unit 140 are respectively electrically different. The high piezoelectric generating unit 150 applies a voltage difference between the nozzle 110 and the spinning collection unit 140. The high temperature electrospinning apparatus 100 can more selectively include a convex lens 160 disposed between the laser generating device 130 and the nozzle 110 such that the laser beam emitted by the laser generating device 130 can be concentrated to the nozzle 110 to the nozzle 110. Perform fixed point heating. The outer surface of the nozzle 110 can be a dark surface such that the nozzle 110 can well absorb the heat generated by the laser beam. The high temperature electrospinning apparatus 100 can more selectively include a heating jacket 170 that is fitted over the spinning supply unit 120. The heating jacket 170 can be an oil bath jacket. The heating jacket 170 can be a hollow structure. The heating jacket 170 has an inlet 172 located below and an outlet 174 located above. The inlet 172 and the outlet 174 of the heating jacket 170 are further connected to the heating device 176. The liquid heated by the heating device 176, such as oil, may enter the hollow heating jacket 170 from the lower inlet 172, and the heating jacket 170 is in heat exchange with the spinning supply unit 120, thereby maintaining the spinning supply unit 120. temperature. The liquid after the heat exchange is again discharged from the outlet 174 and returned to the heating device 176 for heating again. When the polymer solution spinning material is ejected from the ejection opening 114, it is easy to accelerate the solvent volatilization of the polymer solution spinning material due to the pressure difference, so that the concentration of the polymer solution spinning material is too high and it becomes easy to solidify, so that the nozzle 110 is blocked. 201209233 Plug. Therefore, the high temperature electrospinning apparatus 100 in the present embodiment more selectively includes a solvent vapor supply unit 180 to raise the solvent vapor pressure in the vicinity of the injection port 114 of the nozzle 110 to improve the polymer solution spinning at the exit nozzle 110. The moment the solvent evaporates quickly. The solvent vapor supply unit 180 includes a solvent vapor outlet 182, and the solvent vapor outlet 182 is disposed adjacent to the injection port 114. The solvent vapor supply unit 180 can heat the liquid solvent to become a solvent vapor and then eject it from the solvent vapor outlet 182, whereby the solvent vapor increases the solvent vapor pressure near the ejection opening 114 of the nozzle 110 to reduce the polymer solution spinning at the ejection. The condition in which the mouth 114 is cured. The solvent vapor supply unit 180 further includes a loop cover 184, the loop cover 184 is sleeved on the nozzle 110, the loop cover 184 has a gap g between the nozzle 110, and the solvent vapor outlet 182 is connected to the loop cover 184 such that the solvent vapor outlet 182 The ejected solvent vapor enters the gap g between the ring cover 184 and the nozzle 110. The solvent vapor supply unit 180 further includes a loop opening 186 having the same opening direction as the ejection opening 114. The ring cover 184 further has a laser channel 188. The laser channel 188 can be a hole in the ring cover 184 and is disposed corresponding to the traveling path of the laser beam, so that the laser beam generated by the laser generating device 130 passes through the thunder. The channel 188 is applied to the nozzle 110 to perform spot heating of the nozzle 110. The high temperature electrospinning apparatus 100 may more optionally include an infrared heater 190. The infrared heater 190 can be disposed on one side of the nozzle 110, and the infrared heater 190 can emit infrared light with heat to heat the surrounding environment, thereby maintaining the temperature of the surrounding environment. Referring to Fig. 3, there is shown a flow chart showing an embodiment of the electrospinning method of the high temperature electrospinning apparatus 201209233 to which the present invention is applied. Step 3i is to provide a polymer solution spinning to the nozzle, and then step 320 is to generate a laser beam by the laser generating device to direct the laser beam to the heating nozzle, and step 33 is to supply a voltage difference to the nozzle and the spinning collection. The unit causes the polymer solution spinning material to be electrospinned through a nozzle to be collected by a spinning collection unit. In addition to being applied to general electrospun materials, the present invention is particularly suitable for crystalline polymers which cannot be dissolved at room temperature. The crystalline polymers and the salts thereof can be UHMWPE/Bu4NC104, LLDPE/Bu4NC104, mPE. /Bu4NC104, LLDPE/mPE/Bu4NC104, iPP/Bu4NC104, the solvent used may be 〇dcb. See Experimental Example 1: Solution Temperature Laser Usage or Not Droplet Temperature Duration Fiber Form Fiber Size 130 °C No 48-60°C 2 Minute Flat Fiber 1801±220 nm 130 °C 100~110°C Continuous Flat Fiber 1525 + 295 nm In Experimental Example 1, iPP/Bu4NCl〇4 was used as a raw material, and 〇dcb was used as a solvent. It can be seen from the table that in the case of no laser, the temperature of the droplet is significantly reduced, which tends to cause nozzle clogging, so that the process time can only be maintained for 2 minutes, and the target of mass production cannot be achieved. Applying a laser beam to the whistle can reliably and effectively maintain the temperature of the droplet at the nozzle and extend the nozzle usage time.

Referring to Figs. 4A and 4B, respectively, photographs of nozzles in Experimental Example 2 using LLDPE/Bu4NC104 10/0.8 wt% as raw materials without using a laser and using a laser for a certain period of time are shown. It can be seen from Fig. 4A that if laser heating is not used, the nozzle will be clogged after a period of time (after 1 minute in this figure) and cannot be used any more. In contrast, the nozzle of Figure 4B, which uses laser heating, remains unblocked after the same period of use. It will be apparent from the above-described preferred embodiments of the present invention that the application of the present invention has the following advantages. The high-temperature electrospinning device utilizes a laser beam to perform directivity heating of the nozzle, and the non-contact heating method can effectively solve the problem that the temperature of the tiny needle is difficult to maintain, and the polymer solution is solidified to block the nozzle. The situation. With such a high-temperature electrospinning apparatus and method, a crystalline polymer which cannot be dissolved at room temperature can be subjected to electrospinning in this manner. Although the present invention has been described above in terms of a preferred embodiment, it is not intended to limit the invention, and it is obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.
