Description

滾筒式近場靜電紡絲裝置Drum type near field electrospinning device

本發明係關於一種收集近場靜電紡絲之裝置,尤其是一種可連續收集近場靜電紡絲之滾筒式近場靜電紡絲裝置。The invention relates to a device for collecting near-field electrospinning, in particular to a drum-type near-field electrospinning device capable of continuously collecting near-field electrospinning.

習知的靜電紡絲裝置大致包含一原料供應器、一收集器及一電源供應器,該原料供應器及收集器相對設置並相距約數十公分,該電源供應器連接該原料供應器及收集器,以於該原料供應器及收集器之間形成一電場。該原料供應器可容裝聚合物溶液,且該原料供應器具有一噴絲部,該聚合物溶液可由該噴絲部噴出而形成一奈米纖維,該收集器可承接並收集該奈米纖維。然而,由於該奈米纖維內部電荷所產生之排斥作用,使得該奈米纖維會產生橫向波動,而無法呈直線地向該收集器延伸,因此該收集器上的奈米纖維通常係呈無序地紊亂排列狀,故靜電紡絲技術多用於製造不織布。The conventional electrospinning device generally comprises a raw material supply, a collector and a power supply. The raw material supply and the collector are oppositely disposed and spaced apart by about several tens of centimeters, and the power supply is connected to the raw material supply and collected. And an electric field is formed between the raw material supply and the collector. The raw material supply container can accommodate a polymer solution, and the raw material supply device has a spinning portion, and the polymer solution can be ejected from the spinning portion to form a nanofiber, and the collector can receive and collect the nanofiber. However, due to the repulsion caused by the internal charge of the nanofiber, the nanofiber will cause lateral fluctuation and cannot extend linearly to the collector, so the nanofiber on the collector is usually disordered. Since the ground is disorderly arranged, the electrospinning technology is mostly used for manufacturing non-woven fabrics.

近年來,靜電紡絲之技術被應用於製造具高壓電特性之奈米纖維,以驅動如奈米壓電微感測器或奈米壓電微發電機等微機電系統。值得注意的是,除了原料的選擇之外,奈米纖維還需「極化」才能具有壓電特性,而極化須經過高電壓、拉扯及加熱等三個步驟,且極化愈完全,奈米纖維之壓電特性愈顯著。其中,為能夠有方向性地拉扯奈米纖維,以提升拉扯步驟所能產生之極化效果,可縮短該原料供應器之噴絲部與該收集器之間的距離,從數十公分縮短至三毫米以內,以達「近場」收集的效果。In recent years, electrospinning technology has been applied to the manufacture of nanofibers with high-voltage electrical characteristics to drive microelectromechanical systems such as nano piezoelectric micro-sensors or nano-piezoelectric micro-generators. It is worth noting that in addition to the choice of raw materials, nanofibers need to be "polarized" to have piezoelectric properties, and the polarization must be subjected to three steps of high voltage, pulling and heating, and the polarization is more complete. The piezoelectric properties of rice fibers are more pronounced. Wherein, in order to be able to pull the nanofibers in a directional manner to enhance the polarization effect of the pulling step, the distance between the spinning portion of the raw material supply and the collector can be shortened, from tens of centimeters to Within three millimeters, the effect of "near field" collection is achieved.

請參閱第1圖,係為習知近場靜電紡絲裝置之示意圖。習知的近場靜電紡絲裝置9大致包含有一原料供應器91、一平面收集板92及一電源供應器93,該原料供應器91及平面收集板92相對設置,該電源供應器93連接該原料供應器91及平面收集板92,以於該原料供應器91及平面收集板92之間形成一高壓靜電場;該原料供應器91可容裝聚合物溶液L,且該原料供應器91具有一噴絲部911,使得該聚合物溶液L可由該噴絲部911噴出,並於高壓靜電場之作用下形成一電紡絲F;該平面收集板92可架設於一雙軸式數位控制平台94,以帶動該平面收集板92於X-Y平面上產生位移,從而有序地在該平面收集板92上收集由該噴絲部911噴出之電紡絲F;完成收集後,則將該平面收集板92上的電紡絲F取下,並放入一加熱裝置(圖未繪示)中進行烘烤,使該電紡絲F上殘餘之溶劑揮發,以完成電紡絲F之極化。Please refer to FIG. 1 , which is a schematic diagram of a conventional near field electrospinning device. The conventional near-field electrospinning device 9 generally includes a raw material supply unit 91, a planar collecting plate 92, and a power supply unit 93. The raw material supply unit 91 and the planar collecting plate 92 are oppositely disposed, and the power supply unit 93 is connected thereto. a raw material supply unit 91 and a flat collecting plate 92 to form a high voltage electrostatic field between the raw material supply unit 91 and the flat collecting plate 92; the raw material supply unit 91 can accommodate the polymer solution L, and the raw material supply unit 91 has a spinning portion 911, such that the polymer solution L can be ejected from the spinning portion 911, and an electrospinning F is formed under the action of a high-voltage electrostatic field; the planar collecting plate 92 can be erected on a biaxial digital control platform 94, in order to drive the plane collecting plate 92 to generate displacement on the XY plane, so that the electrospinning F sprayed by the spinning portion 911 is collected on the plane collecting plate 92 in an orderly manner; after the collection is completed, the plane is collected. The electrospinning F on the plate 92 is removed and placed in a heating device (not shown) for baking to volatilize the residual solvent on the electrospinning F to complete the polarization of the electrospinning F.

其中,由於該近場靜電紡絲裝置9將該原料供應器91之噴絲部911與該平面收集板92之間的距離,從傳統的數百毫米縮短至三毫米以內,因此由該噴絲部911噴出之電紡絲F在受內部電荷影響而產生橫向波動前,即已噴至該平面收集板92上,故可隨該雙軸式數位控制平台94之帶動而有序地排列於該平面收集板92。且收集的過程中,剛噴出的電紡絲F可受已附著於該平面收集板92的部份牽引而被拉扯,並反覆進行同一方向的拉扯動作,故透過該近場靜電紡絲裝置9收集到的電紡絲F,在配合進行加熱步驟之後即可具有壓電特性。Wherein, since the near-field electrospinning device 9 shortens the distance between the spinning portion 911 of the raw material supplier 91 and the plane collecting plate 92 from the conventional hundreds of millimeters to within three millimeters, the spinning is performed by the spinning The electrospinning F sprayed by the portion 911 is sprayed onto the plane collecting plate 92 before being subjected to lateral fluctuation due to the internal charge, so that it can be arranged in an orderly manner along with the driving of the biaxial digital control platform 94. Plane collection plate 92. During the collection process, the electrospinning F that has just been ejected can be pulled by the portion that has been attached to the flat collecting plate 92, and is pulled in the same direction, so that the near-field electrospinning device 9 is transmitted through the near field. The collected electrospinning F has piezoelectric characteristics after being subjected to a heating step.

請配合參閱第2圖,為連續收集以提升收集電紡絲F之效率,該近場靜電紡絲裝置9可藉由該雙軸式數位控制平台94之帶動,使該平面收集板92收集到之電紡絲F呈數個端部相連之ㄇ形態樣。惟,由該近場靜電紡絲裝置9所收集到的電紡絲F,不僅其收集長度受到該雙軸式數位控制平台94之進程限制,單次收集的量也受限於該平面收集板92之面積,使得收集電紡絲F之效率仍太不理想;再且,該電紡絲F在轉折處易產生粗細不均的現象,從而影響該電紡絲F之壓電特性表現,且轉折處也易產生應力集中的現象,使得該電紡絲F在後續使用時,常會在各轉折處發生斷裂。Please refer to FIG. 2 for continuous collection to improve the efficiency of collecting electrospinning F. The near-field electrospinning device 9 can be driven by the biaxial digital control platform 94 to collect the planar collecting plate 92. The electrospinning F is in the form of a plurality of ends connected to each other. However, the electrospinning F collected by the near-field electrospinning device 9 is not only limited in its collection length by the process of the biaxial digital control platform 94, but also the amount of single collection is limited to the planar collecting plate. The area of 92 makes the efficiency of collecting electrospinning F still unsatisfactory; furthermore, the electrospinning F tends to produce unevenness in thickness at the turning point, thereby affecting the piezoelectric characteristics of the electrospinning F, and The phenomenon of stress concentration is also likely to occur at the turning point, so that the electrospinning F often breaks at each turn in the subsequent use.

另,一般而言,為連接該電源供應器93以產生高壓靜電場,該平面收集板92多為金屬製品而具有良好的導電性;然而,由於該噴絲部911至該平面收集板92之距離甚微,因此受地心引力影響而欲向下滴出的聚合物溶液L液滴,常在轉變成絲狀的電紡絲F之前就與該平面收集板92接觸而發生短路,造成該段電紡絲F燒毀,因此該習知近場靜電紡絲裝置9收集具壓電特性之電紡絲F的效果並不理想。In addition, in general, in order to connect the power supply 93 to generate a high voltage electrostatic field, the planar collecting plate 92 is mostly a metal product and has good electrical conductivity; however, due to the spinning portion 911 to the planar collecting plate 92 The distance is very small, so that the droplets of the polymer solution L which are to be dripped downward by the gravitational force are often short-circuited by contact with the plane collecting plate 92 before being converted into the filament-shaped electrospinning F, resulting in the short circuit. The segment electrospinning F is burned, so that the effect of the conventional near-field electrospinning device 9 for collecting electrospinning F having piezoelectric characteristics is not satisfactory.

本發明目的乃解決上述習知近場靜電紡絲裝置之缺點,以提供一種滾筒式近場靜電紡絲裝置,係可透過連續收集的方式,增長電紡絲之收集長度,使得單次收集到之電紡絲的總量得以增加。The object of the present invention is to solve the shortcomings of the above-mentioned conventional near-field electrospinning device, and to provide a drum-type near-field electrospinning device capable of increasing the collection length of electrospinning through continuous collection, so that a single collection is obtained.
