Description

本発明はカーボンナノチューブ(以下、CNTともいう)の構造体(以下、CNT構造体ともいう)の製造方法および製造装置に関する。   The present invention relates to a method for manufacturing a carbon nanotube (hereinafter also referred to as CNT) structure (hereinafter also referred to as a CNT structure) and a manufacturing apparatus.

CNTは、グラフェンからなる外側面を有するという特異的な構造を有するため、様々な分野における機能材料や構造材料への応用が期待されている。CNTの有する優れた特性としては、機械的強度が高く、質量が軽く、電気伝導特性が良く、耐熱性、熱伝導性などの熱特性が良く、化学的耐腐食性が高く、且つ電界電子放出特性がよいことが挙げられる。したがって、CNTを応用した機能材料や構造材料の具体的な用途として、軽量高強度ワイヤ、走査プローブ顕微鏡(SPM)の探針、電界放出ディスプレイ(FED)の冷陰極、導電性樹脂、高強度樹脂、耐腐食性樹脂、耐摩耗性樹脂、高度潤滑性樹脂、二次電池や燃料電池の電極、LSIの層間配線材料、バイオセンサーなどが考えられている。   Since CNT has a specific structure of having an outer surface made of graphene, it is expected to be applied to functional materials and structural materials in various fields. The excellent properties of CNTs include high mechanical strength, light mass, good electrical conductivity, good thermal properties such as heat resistance and thermal conductivity, high chemical corrosion resistance, and field electron emission. The characteristic is good. Therefore, specific applications of functional materials and structural materials using CNT include lightweight high-strength wires, scanning probe microscope (SPM) probes, field emission display (FED) cold cathodes, conductive resins, and high-strength resins. Corrosion-resistant resins, abrasion-resistant resins, highly lubricious resins, secondary battery and fuel cell electrodes, LSI interlayer wiring materials, biosensors, and the like are considered.

種々の用途に応用可能なCNT構造体の製造方法として、簡単な工程による高効率な製造を目的として、相互に平行であり基板に垂直な複数のCNTを含むCNTアレイから、ウェブやフィルム等を引き出す製造方法が提案されている(例えば、特許文献1)。
特許文献1には、CNTアレイの端部に接着面を接着させてCNTフィルムを引き出すCNT構造体の製造方法において、複数のCNTを基板に0〜90°の角度で傾倒させて接着面との接触面積を増大させる方法が記載されている。当該方法は、CNTフィルムを均一に引き出すために、CNTアレイの端部を引出開始位置としてCNT構造体の製造する方法である。
As a method of manufacturing a CNT structure applicable to various uses, for the purpose of high-efficiency manufacturing by a simple process, a web, a film, or the like is obtained from a CNT array including a plurality of CNTs parallel to each other and perpendicular to a substrate. A manufacturing method for drawing out has been proposed (for example, Patent Document 1).
In Patent Document 1, in a method of manufacturing a CNT structure in which an adhesive surface is bonded to an end of a CNT array and a CNT film is drawn out, a plurality of CNTs are tilted at an angle of 0 to 90 ° with respect to the substrate. A method for increasing the contact area is described. This method is a method of manufacturing a CNT structure using the end of the CNT array as a drawing start position in order to draw the CNT film uniformly.

特開2010−248069号公報JP 2010-248069 A

しかし、CNTアレイの端部は、内部と比較してCNTの均一性が低いことが多い。このため、特許文献1に記載されているCNT構造体の製造方法では、仮にCNTアレイ端部のCNTを十分に接着できたとしても、CNTアレイ端部の均一性の低さに起因して、均一なCNT構造体を引き出せないことがある。
そこで、本発明は、端部の均一性が低いCNTアレイを原料とする場合でも、ウェブやフィルム等のCNT構造体を容易かつ安定的に引き出して、均一性の高いCNT構造体を形成することができる製造方法および装置の提供を目的としている。
However, the end portion of the CNT array is often less uniform in CNT than the inside. For this reason, in the manufacturing method of the CNT structure described in Patent Document 1, even if the CNTs at the end of the CNT array can be sufficiently bonded, due to the low uniformity of the CNT array end, A uniform CNT structure may not be pulled out.
Therefore, the present invention can easily and stably pull out a CNT structure such as a web or a film to form a highly uniform CNT structure even when a CNT array with low uniformity at the end is used as a raw material. It is an object of the present invention to provide a manufacturing method and apparatus capable of performing the above.

[CNT構造体の製造方法]
基板表面に配列された複数のCNTを含むCNTアレイの一部からCNT構造体を引き出すCNT構造体の製造方法として、本発明を実施する形態について、以下、説明する。
Hereinafter, embodiments of the present invention will be described.
[Method for producing CNT structure]
As a method for manufacturing a CNT structure in which a CNT structure is drawn from a part of a CNT array including a plurality of CNTs arranged on the substrate surface, an embodiment for carrying out the present invention will be described below.

図1(a)〜(c)は、本実施形態のCNT構造体の製造方法を模式的に示している。図1(a)はCNTアレイの表面側から引出開始位置設定手段の挿入を開始する段階(所定位置Xへ移動させる前)の斜視図であり、図1(b)は引出開始位置設定手段をCNTアレイに挿入して、所定位置Xで停止させた段階の斜視図であり、図1(c)はCNTアレイのCNT供給源側から離れる方向に引出開始位置設定手段を移動させた段階(所定位置Xから移動させた後)の斜視図である。図1(a)〜図1(c)を参酌しつつ、本実施形態のCNT構造体の製造方法における、引出開始位置設定ステップおよび引出ステップについて説明する。   1A to 1C schematically show a method for manufacturing a CNT structure according to this embodiment. FIG. 1 (a) is a perspective view of a stage of starting the insertion of the drawing start position setting means from the surface side of the CNT array (before moving to the predetermined position X), and FIG. 1 (b) is a drawing start position setting means. FIG. 1C is a perspective view of a stage where the CNT array is inserted and stopped at a predetermined position X, and FIG. 1C is a stage where the extraction start position setting means is moved in a direction away from the CNT supply source side of the CNT array (predetermined It is a perspective view after moving from the position X. The drawing start position setting step and the drawing step in the method of manufacturing the CNT structure according to the present embodiment will be described with reference to FIGS.

[引出開始位置設定ステップ]
引出開始位置設定ステップは、CNTアレイの表面側から基板側に引出開始位置設定手段を移動させて、所定位置で停止させることにより、CNTアレイに引出開始位置を設定する工程である。本実施形態において、「CNTアレイの表面」とは、CNTの先端により形成される面をいう。CNTの先端側をCNTアレイの「表面側」といい、基板のCNTアレイが成長する面を基板表面という。CNTが基板と接している側をCNTアレイの「基板側」または「基板表面側」という。
[Drawer start position setting step]
The extraction start position setting step is a step of setting the extraction start position in the CNT array by moving the extraction start position setting means from the surface side of the CNT array to the substrate side and stopping at a predetermined position. In the present embodiment, the “surface of the CNT array” refers to a surface formed by the tips of the CNTs. The tip side of the CNT is called the “surface side” of the CNT array, and the surface of the substrate on which the CNT array grows is called the substrate surface. The side where the CNT is in contact with the substrate is referred to as the “substrate side” or “substrate surface side” of the CNT array.

図1(a)〜図1(c)のうち、図1(a)から図1(b)までの工程が引出開始位置設定ステップに相当する。図1(a)に示すように、CNTアレイ2の表面21側からCNTアレイ2内部に引出開始位置設定手段1を挿入して、図1(b)に示すように、挿入した引出開始位置設定手段1を所定位置Xで停止させて、引出開始位置23を設定する。引出開始位置設定手段1が所定位置Xに挿入された状態においては、引出開始位置設定手段1と基板表面31との間には、CNT供給源2Aと除去部2Bとを接続する連続部2Cが形成される。   1A to 1C, the steps from FIG. 1A to FIG. 1B correspond to the drawing start position setting step. As shown in FIG. 1 (a), the drawer start position setting means 1 is inserted into the CNT array 2 from the surface 21 side of the CNT array 2, and the inserted drawer start position is set as shown in FIG. 1 (b). The means 1 is stopped at the predetermined position X, and the drawing start position 23 is set. In a state where the extraction start position setting means 1 is inserted at the predetermined position X, a continuous part 2C connecting the CNT supply source 2A and the removal part 2B is provided between the extraction start position setting means 1 and the substrate surface 31. It is formed.

図1(a)〜図1(c)では、引出開始位置設定手段1を移動させて、CNTアレイ2内に挿入する例を示している。しかし、引出開始位置設定ステップは、引出開始位置設定手段1をCNTアレイ2内に挿入する場合のみではなく、引出開始位置設定手段1を移動させて、CNTアレイ2の端22を有する部分を表面21側から基板3方向に押しつぶす場合も含んでいる(図8参照)。   1A to 1C show an example in which the drawing start position setting means 1 is moved and inserted into the CNT array 2. However, in the drawing start position setting step, not only the drawing start position setting means 1 is inserted into the CNT array 2, but the drawing start position setting means 1 is moved so that the portion having the end 22 of the CNT array 2 is surfaced. This includes the case of crushing from the 21 side toward the substrate 3 (see FIG. 8).

引出開始位置設定ステップにおいて引出開始位置設定手段1を所定位置Xまで挿入することにより、引出ステップによりCNTアレイ2が分割される引出開始位置23を規定できる。引出ステップにより、基板表面21上に残ってCNT供給源となるCNTアレイ2の一方をCNT供給源2Aといい、基板表面21から取り除かれるCNTアレイ2の他方を除去部2Bという。図1(c)には、引出開始位置設定手段1とともに除去部2Bを所定位置Xから移動させて除去部2Bを取り除く例を示した。しかし、除去部2BをCNT供給源側から離れる方向に移動させる手段として、引出開始位置設定手段1とは別の部材を用いてもよい。例えば、引出開始位置設定手段1とともに除去部2Bを所定位置Xから移動せることなく、別の部材を用いて除去部2Bを取り除くこととしてもよい。   By inserting the drawing start position setting means 1 to the predetermined position X in the drawing start position setting step, the drawing start position 23 where the CNT array 2 is divided by the drawing step can be defined. One of the CNT arrays 2 remaining on the substrate surface 21 and serving as the CNT supply source by the extraction step is referred to as a CNT supply source 2A, and the other of the CNT arrays 2 removed from the substrate surface 21 is referred to as a removal unit 2B. FIG. 1C shows an example in which the removal unit 2B is moved from the predetermined position X together with the drawing start position setting unit 1 to remove the removal unit 2B. However, a member other than the drawing start position setting unit 1 may be used as a unit that moves the removal unit 2B in a direction away from the CNT supply source side. For example, the removal unit 2B may be removed using another member without moving the removal unit 2B from the predetermined position X together with the drawing start position setting unit 1.

CNTアレイの連続部2Cは、後の引出ステップでCNT構造体が最初に引き出される引出開始位置23となる。引出開始位置設定ステップにより、CNTアレイ2の端22ではなく、CNTアレイ2内に引出開始位置23を設定する。CNTの均一性が高い連続部2Cが引出開始位置23となるから、後の引出ステップによって引き出しを開始した最初の段階から均質なCNT構造体4を製造することが可能になる。   The continuous portion 2C of the CNT array becomes the extraction start position 23 from which the CNT structure is first extracted in a subsequent extraction step. In the extraction start position setting step, the extraction start position 23 is set not in the end 22 of the CNT array 2 but in the CNT array 2. Since the continuous portion 2C having high CNT uniformity is the extraction start position 23, it is possible to manufacture the homogeneous CNT structure 4 from the first stage where the extraction is started in the subsequent extraction step.

[引出ステップ]
引出ステップは、CNTアレイの除去部をCNTアレイの除去部側(CNT供給源の反対側)に移動させてCNT構造体を引き出すステップであり、引出位置設定ステップにおいて引出開始位置設定手段により規定された除去部をCNTアレイから取り除いてCNT構造体を引き出す工程である。
[Drawing step]
The extraction step is a step of extracting the CNT structure by moving the removal unit of the CNT array to the removal unit side of the CNT array (opposite side of the CNT supply source), and is defined by the extraction start position setting means in the extraction position setting step. In this step, the removed portion is removed from the CNT array and the CNT structure is pulled out.

図1(a)〜図1(c)のうち、図1(b)から図1(c)までの工程(引出開始位置設定手段を所定位置Xから移動させる工程)が引出ステップに相当する。図1(b)に示すように、引出開始位置設定手段1を所定位置Xで停止させた後に、図1(c)に示すように、除去部2B側の方向(CNT供給源2Aとは反対側の方向)に引出開始位置設定手段1を移動させる。引出開始位置設定手段1を移動させることにより、CNT供給源2AからCNT構造体4を連続的に引き出す。   1A to 1C, the process from FIG. 1B to FIG. 1C (the process of moving the extraction start position setting means from the predetermined position X) corresponds to the extraction step. As shown in FIG. 1 (b), after the drawing start position setting means 1 is stopped at the predetermined position X, as shown in FIG. 1 (c), the direction toward the removal unit 2B (opposite to the CNT supply source 2A) The drawing start position setting means 1 is moved in the direction of the side). By moving the drawing start position setting means 1, the CNT structure 4 is continuously pulled out from the CNT supply source 2A.

引出ステップにおいて、引出開始位置設定手段1を除去部2B側に移動させるとは、所定位置Xを基準として、CNT供給源2Aとは反対側に引出開始位置設定手段1を移動させることをいう。   In the extraction step, the movement of the extraction start position setting means 1 toward the removal unit 2B means that the extraction start position setting means 1 is moved to the side opposite to the CNT supply source 2A with the predetermined position X as a reference.

なお、図1(c)には、引出開始位置設定手段1を基板3の基板表面31に対して斜め方向(図中では右下の方向)に移動させる形態を示したが、このように引出開始位置設定手段1を基板表面31と完全に平行な方向(基板表面31に対して0°の方向)に移動させることは必要でなく、基板表面31に対して斜め方向に引出開始位置設定手段1を移動させてもよい。引出開始位置設定手段1の移動方向は、基板表面31に対して0°〜70°の範囲とすることが好ましい。   FIG. 1C shows a form in which the drawing start position setting means 1 is moved in an oblique direction (lower right direction in the drawing) with respect to the substrate surface 31 of the substrate 3. It is not necessary to move the start position setting means 1 in a direction completely parallel to the substrate surface 31 (a direction of 0 ° with respect to the substrate surface 31), and the drawing start position setting means is inclined with respect to the substrate surface 31. 1 may be moved. The moving direction of the drawing start position setting means 1 is preferably in the range of 0 ° to 70 ° with respect to the substrate surface 31.

[板状部材]
図2は、図1(b)のA−A矢視断面図であり、本発明の実施形態に係るCNT構造体の製造方法において用いられる引出開始位置設定手段の断面形状の一例について引出開始位置設定手段が所定位置Xで停止した段階を示している。同図に示すように、引出開始位置設定ステップにおける所定位置Xは、引出開始位置設定手段(板状部材)1が基板表面31に接触しない位置であり、引出開始位置設定手段1と基板表面31との間にCNTアレイ2の連続部2Cを形成する。このようにCNT供給源2Aと除去部2Bとの間に連続部2Cを形成することにより、引出開始位置設定手段1をCNT供給源2Aの反対側に移動させる引出ステップにおいて、連続部2Cを引出開始位置23としてCNT構造体4を引き出すことができる。
[Plate-shaped member]
FIG. 2 is a cross-sectional view taken along the line AA in FIG. 1 (b) and shows an example of the drawing start position of the drawing start position setting means used in the method for manufacturing a CNT structure according to the embodiment of the present invention. A stage where the setting means stops at a predetermined position X is shown. As shown in the drawing, the predetermined position X in the drawing start position setting step is a position at which the drawing start position setting means (plate member) 1 does not contact the substrate surface 31, and the drawing start position setting means 1 and the substrate surface 31 are not in contact with each other. A continuous portion 2C of the CNT array 2 is formed between the two. Thus, by forming the continuous part 2C between the CNT supply source 2A and the removal part 2B, the continuous part 2C is pulled out in the extraction step of moving the extraction start position setting means 1 to the opposite side of the CNT supply source 2A. The CNT structure 4 can be pulled out as the start position 23.

CNTアレイ2の高さをHとし、CNTアレイ2の連続部2Cの高さをHcとすると、引出開始位置設定ステップにおいて、引出開始位置設定手段1を所定位置Xに挿入した状態における、連続部2Cの高さをHcが下記の式(1)を満たすことが好ましい。
0.1H≦H≦0.9H・・・(1)
Assuming that the height of the CNT array 2 is H and the height of the continuous portion 2C of the CNT array 2 is Hc, the continuous portion in the state where the extraction start position setting means 1 is inserted at the predetermined position X in the extraction start position setting step. It is preferable that the height of 2C satisfies the following formula (1).
0.1H ≦ H C ≦ 0.9H (1)

連続部2Cの高さHを0.9H以下とすること、すなわちCNTアレイの表面21から引出開始位置設定手段1を挿入する距離を0.1H以上とすることより、引出開始位置設定ステップの後の引出ステップにおいて、除去部2Bを安定的に引出開始位置設定手段1とともに移動させることができる。 The continuous portion 2C height H C or less 0.9H, i.e. than to a distance of inserting a pull-out start position setting unit 1 from the surface 21 of the CNT array with more than 0.1H, lead start position setting step In the subsequent extraction step, the removal unit 2B can be moved together with the extraction start position setting means 1 in a stable manner.

連続部2Cの高さHを0.1H以上とすること、すなわちCNTアレイの表面21から引出開始位置設定手段1を挿入する距離を0.9H以下とすることより、引出開始位置設定ステップの後の引出ステップによってCNTアレイ2が分割されることを防止して、安定的に引出開始位置23からCNT構造体4を引き出すことができる。 It is of the continuous portion 2C height H C or more 0.1H, i.e. than to a distance of inserting a pull-out start position setting unit 1 from the surface 21 of the CNT array than 0.9H, lead start position setting step It is possible to prevent the CNT array 2 from being divided by the subsequent extraction step, and to stably extract the CNT structure 4 from the extraction start position 23.

基板表面31からのCNTアレイ2の高さHは限定されないが、例えば、0.2mm〜1.5mm程度とすれば、安定的に引出開始位置23とからCNT構造体4を引き出すことができる。   The height H of the CNT array 2 from the substrate surface 31 is not limited. For example, if the height H is about 0.2 mm to 1.5 mm, the CNT structure 4 can be stably pulled out from the extraction start position 23.

図2に示すように、CNTアレイ2の端22は凹凸などが形成され不均一であることが多い。このため、端22を引出開始位置としてCNT構造体4(図1(c)参照)を引き出すと、端22の凹凸に影響されて、均一なCNT構造体4を引き出すことが困難である。そこで、本実施形態の製造方法は、CNTアレイ2の表面21側から引出開始位置設定手段1を挿入することにより、端22から内側に入った均一性の高いCNTアレイ2の領域に連続部2Cを形成して、引出開始位置23とする。端22からどの程度離れた位置を連続部2Cとするかは、CNTアレイ2の端22の不均一性や、CNT構造体4に要求される均一性などに応じて、適宜設定することができる。   As shown in FIG. 2, the end 22 of the CNT array 2 is often uneven due to the formation of irregularities. For this reason, when the CNT structure 4 (see FIG. 1C) is pulled out with the end 22 as the extraction start position, it is difficult to pull out the uniform CNT structure 4 due to the unevenness of the end 22. Therefore, in the manufacturing method of the present embodiment, by inserting the drawing start position setting means 1 from the surface 21 side of the CNT array 2, the continuous portion 2 </ b> C is formed in the region of the highly uniform CNT array 2 entering from the end 22. Is formed as a drawing start position 23. How far away from the end 22 is the continuous portion 2C can be appropriately set according to the non-uniformity of the end 22 of the CNT array 2, the uniformity required for the CNT structure 4, and the like. .

図2では、引出開始位置設定手段1の基板3側が基板表面31と略平行な端面10を備えている断面矩形の板状部材を示す。同図に示すように、端面10を備える引出開始位置設定手段1を用いた場合、引出開始位置設定ステップにおいて引出開始位置設定手段1を挿入することにより(図1(a)および図1(b)参照)、端面10によりCNTアレイ2が押しつぶされて連続部2CのCNT密度が高くなる。したがって、引出開始位置設定手段1を所定位置で停止させた段階では、CNT供給源2Aと除去部Bとが密度の高い連続部Cにより接続されるから、安定的に連続部Cを引出開始位置23としてCNT構造体を引き出ことができる。   In FIG. 2, a plate-like member having a rectangular cross section in which the substrate 3 side of the drawing start position setting means 1 has an end face 10 substantially parallel to the substrate surface 31 is shown. As shown in the figure, when the drawer start position setting means 1 having the end face 10 is used, the drawer start position setting means 1 is inserted in the drawer start position setting step (FIGS. 1A and 1B). )), The CNT array 2 is crushed by the end face 10, and the CNT density of the continuous portion 2C is increased. Therefore, at the stage where the drawing start position setting means 1 is stopped at a predetermined position, the CNT supply source 2A and the removal unit B are connected by the continuous portion C having a high density, so that the continuous portion C is stably pulled out. As 23, the CNT structure can be pulled out.

図3は、断面形状が異なる引出開始位置設定手段の他の一例が所定位置Xで停止した段階を示す断面図である。同図に示す引出開始位置設定手段(板状部材)5の断面形状は、CNT構造体2に挿入される側に2つの傾斜面51を備え、基板表面31側端に向かって徐々に細くなり、端部50を備えた先細りのテーパー状である。CNT構造体2に挿入される側の断面形状を先細りのテーパー状とすることにより、CNTアレイ2の表面21側からの挿入を円滑にすることができる。したがって、引出開始位置設定手段5を挿入することによって、CNT構造体2のCNTの配列状態が乱されることを抑制できる。   FIG. 3 is a cross-sectional view showing a stage where another example of the drawing start position setting means having a different cross-sectional shape stops at the predetermined position X. The cross-sectional shape of the drawing start position setting means (plate-like member) 5 shown in the figure is provided with two inclined surfaces 51 on the side to be inserted into the CNT structure 2 and gradually becomes narrower toward the substrate surface 31 side end. The taper is tapered with an end 50. By making the cross-sectional shape on the side inserted into the CNT structure 2 into a tapered shape, insertion from the surface 21 side of the CNT array 2 can be made smooth. Therefore, by inserting the drawing start position setting means 5, it is possible to prevent the CNT arrangement state of the CNT structure 2 from being disturbed.

図4は、断面形状が異なる引出開始位置設定手段のさらに他の一例が所定位置Xで停止した段階を示す断面図である。同図に示す引出開始位置設定手段6の断面形状は、端部60を備えている点において、端部50を備えた引出開始位置設定手段5と同様であるが、一方側のみが傾斜面61である点において、両側とも傾斜面51である引出開始位置設定手段5とは異なっている。しかし、引出開始位置設定手段(板状部材)6がCNTアレイ2の表面21側からの挿入を円滑化する作用を奏するという点は、引出開始位置設定手段5と同じである。なお、図4には、CNT供給源2Aとは反対側の除去部2B側のみに傾斜面61を形成した例を示したが、CNT供給源2A側のみを傾斜面61としてもよい。   FIG. 4 is a cross-sectional view showing a stage where still another example of the drawing start position setting means having a different cross-sectional shape stops at the predetermined position X. The sectional shape of the drawing start position setting means 6 shown in the figure is the same as that of the drawing start position setting means 5 provided with the end portion 50 in that the end portion 60 is provided. Is different from the drawing start position setting means 5 which is the inclined surface 51 on both sides. However, it is the same as the drawing start position setting means 5 in that the drawing start position setting means (plate member) 6 has an effect of facilitating insertion from the surface 21 side of the CNT array 2. 4 shows an example in which the inclined surface 61 is formed only on the removal portion 2B side opposite to the CNT supply source 2A, the inclined surface 61 may be formed only on the CNT supply source 2A side.

本実施形態において「先細りのテーパー状」とは、断面形状が端部に向かって徐々に細くなる先細り形状をいい、引出開始位置設定手段として厚みが同じ板状部材を用いた場合に、図2の断面矩形とした構成と比較して、所定位置Xまで挿入される時の抵抗を軽減する作用を奏する形状をいう。図3および図4に示したように、両面が傾斜した両刃形状および一方の面のみが傾斜した片刃形状のいずれでもよい。傾斜は一定である必要は無く、連続的または不連続的に変化するものでもよい。例えば、図5に示したように、端面70および傾斜面71の両方を備えている断面形状が台形である引出開始位置設定手段7も、先細りのテーパー状に含まれる。   In the present embodiment, the “tapered taper shape” refers to a taper shape whose cross-sectional shape gradually narrows toward the end, and when a plate-like member having the same thickness is used as the drawing start position setting means, FIG. Compared to the configuration having a rectangular cross section, it refers to a shape that acts to reduce resistance when inserted to a predetermined position X. As shown in FIGS. 3 and 4, either a double-edged shape with both sides inclined or a single-edged shape with only one side inclined may be used. The inclination does not need to be constant, and may change continuously or discontinuously. For example, as illustrated in FIG. 5, the drawing start position setting means 7 having a trapezoidal cross-sectional shape including both the end surface 70 and the inclined surface 71 is also included in the tapered shape.

[傾斜ステップ]
本実施形態のCNT構造体の製造方法は、引出開始位置設定ステップと、引出ステップとの間に、所定位置において板状部材をCNT引出側のCNTアレイ側に傾ける傾斜ステップを備えていてもよい。
図6(a)および図6(b)は、本発明の実施形態に係るCNT構造体の製造方法における傾斜ステップを模式的に示している。図6(a)は引出開始位置設定手段を所定位置Xで停止させた段階の側面図であり、図6(b)は引出開始位置設定手段の下端を所定位置Xに保持したままで、基板表面の法線Vを基準として引出開始位置設定手段を、除去部側に傾けた段階の側面図である。
[Inclination step]
The manufacturing method of the CNT structure according to the present embodiment may include an inclination step for inclining the plate-like member toward the CNT array side on the CNT extraction side at a predetermined position between the extraction start position setting step and the extraction step. .
FIG. 6A and FIG. 6B schematically show tilt steps in the method for manufacturing a CNT structure according to the embodiment of the present invention. FIG. 6A is a side view of the stage where the drawing start position setting means is stopped at the predetermined position X, and FIG. 6B is a view of the substrate with the lower end of the drawing start position setting means held at the predetermined position X. It is a side view at the stage where the extraction start position setting means is tilted toward the removal portion with respect to the surface normal V.

傾斜ステップは、図6(a)に示すように、引出開始位置設定ステップで引出開始位置設定手段(板状部材)1をCNTアレイ2の所定位置Xに挿入した後、図6(b)に示すように、引出開始位置設定手段1の下端を所定位置Xに保持したままで、CNTアレイ2のCNT供給源2Aとは反対側、すなわち除去部2B側に傾ける工程である。この傾斜ステップにより、引出開始位置設定手段1のCNT供給源2A側の側面1AをCNT供給源2Aから離れる方向に移動させて、引出開始位置設定手段1とCNT供給源2Aとの接触を弱めることができる。同時に、引出開始位置設定手段1の除去部2B側の側面1BをCNTアレイ2の除去部2B側に移動させて、引出開始位置設定手段1の除去部2Bとの接触を強めつつ、除去部2Bを押し固めて塊とする。これにより、引出ステップの開始時に、CNT供給源2Aと接している引出開始位置設定手段1の側面1Aが引出開始位置23となることを防ぎ、除去部2Bを塊状にして移動させることができる。したがって、連続部2Cを引出開始位置23として、CNT供給源2AからCNT構造体4をより安定的に引き出すことができる(図1(a)〜図1(c)参照)。   As shown in FIG. 6 (a), the tilting step is performed as shown in FIG. 6 (b) after the drawing start position setting means (plate member) 1 is inserted into the predetermined position X of the CNT array 2 in the drawing start position setting step. As shown, while the lower end of the drawing start position setting means 1 is held at a predetermined position X, the CNT array 2 is tilted to the side opposite to the CNT supply source 2A, that is, to the removal unit 2B side. By this inclination step, the side surface 1A on the CNT supply source 2A side of the drawing start position setting means 1 is moved away from the CNT supply source 2A to weaken the contact between the drawing start position setting means 1 and the CNT supply source 2A. Can do. At the same time, the side surface 1B on the removal unit 2B side of the extraction start position setting unit 1 is moved to the removal unit 2B side of the CNT array 2 to strengthen the contact with the removal unit 2B of the extraction start position setting unit 1 while removing the unit 2B. Press to harden to make a lump. Thereby, at the start of the extraction step, the side surface 1A of the extraction start position setting means 1 in contact with the CNT supply source 2A can be prevented from becoming the extraction start position 23, and the removal unit 2B can be moved in a lump. Therefore, the CNT structure 4 can be pulled out more stably from the CNT supply source 2A with the continuous portion 2C as the drawing start position 23 (see FIGS. 1A to 1C).

所定位置Xから引出開始位置設定手段1を傾ける角度θ(基板表面31の法線Vと引出開始位置設定手段1の除去部2B側の側面1Bとにより形成される角度)を大きくすれば、引出ステップの前に、板状部材をCNTアレイ供給部との接触を弱めるとともに、引き出される側のCNTアレイの除去部2Bを引出開始位置設定手段で押し固めてブロック化し、より安定なCNTの塊を形成することができる。   If the angle θ for tilting the drawing start position setting means 1 from the predetermined position X (the angle formed by the normal V of the substrate surface 31 and the side surface 1B on the removal portion 2B side of the drawing start position setting means 1) is increased, the drawing is performed. Before the step, the plate-like member is weakened in contact with the CNT array supply unit, and the removed CNT array removal unit 2B is pressed and solidified by the extraction start position setting means to form a more stable block of CNTs. Can be formed.

所定位置Xから引出開始位置設定手段1を傾ける角度θを小さくすれば、基板表面31と平行な方向に引出開始位置設定手段1を移動させる際、安定的に引出開始位置設定手段1に除去部2Bを引っかけて引出開始位置設定手段1と一緒に移動させることができるから、CNT構造体を容易に引き出すことが可能になる。   If the angle θ for inclining the extraction start position setting means 1 from the predetermined position X is reduced, the removal start position setting means 1 can be stably removed by the removal start position setting means 1 when the extraction start position setting means 1 is moved in a direction parallel to the substrate surface 31. Since 2B can be hooked and moved together with the drawing start position setting means 1, the CNT structure can be pulled out easily.

所定位置Xから引出開始位置設定手段1を傾ける角度θは、CNTアレイの性質に応じて適宜調整すればよいが、除去部2BをCNTの塊とする観点から、45°以上89°以下の範囲とすることが好ましい。引出開始位置設定手段1を傾ける角度θを上記の範囲とすることにより、引出開始位置設定手段1により除去部2Bを塊の状態で引出開始位置設定手段1の側面1Bに接着させることができるから、CNT構造体を容易に引き出すことが可能になる。   The angle θ for inclining the drawing start position setting means 1 from the predetermined position X may be adjusted as appropriate according to the properties of the CNT array. However, from the viewpoint of making the removal portion 2B a lump of CNTs, a range of 45 ° or more and 89 ° or less. It is preferable that By setting the angle θ for inclining the drawing start position setting means 1 within the above range, the removal portion 2B can be adhered to the side surface 1B of the drawing start position setting means 1 in a lump state by the drawing start position setting means 1. The CNT structure can be easily pulled out.

図6(a)および図6(b)では、引出開始位置設定手段1を所定位置Xに挿入した後の傾斜ステップにより、除去部2Bを押し固めて塊とする形態を説明した。以下では、図7および図8を参照して、引出開始位置設定手段6を表面21側から基板表面31側に移動させる引出位置設定ステップと同時に、除去部2Bを押し固めて塊とする形態を説明する。   6 (a) and 6 (b), the configuration has been described in which the removal unit 2B is pressed and solidified into a lump by an inclination step after the drawing start position setting means 1 is inserted into the predetermined position X. Hereinafter, referring to FIG. 7 and FIG. 8, a form in which the removal unit 2 </ b> B is pressed and consolidated into a lump simultaneously with the extraction position setting step of moving the extraction start position setting means 6 from the surface 21 side to the substrate surface 31 side. explain.

図7は所定位置(引出開始位置)Xに移動した引出開始位置設定手段6の除去部2B側の側面6BがCNTアレイ2の端22の内側にある場合を示す側面図であり、図8は、所定位置Xに移動した引出開始位置設定手段6の除去部2B側の側面6BがCNTアレイ2の端22よりも外側にある場合を示す側面図である。   FIG. 7 is a side view showing a case where the side surface 6B on the removal portion 2B side of the drawing start position setting means 6 moved to a predetermined position (drawing start position) X is inside the end 22 of the CNT array 2, and FIG. FIG. 6 is a side view showing a case where the side surface 6B on the removal portion 2B side of the drawing start position setting means 6 moved to the predetermined position X is outside the end 22 of the CNT array 2.

図7および図8に示すように、引出位置設定ステップにおいて、引出開始位置設定手段6がCNTアレイ2の表面21から所定位置Xに移動すると同時に、斜面61によって、除去部2BのCNTを押し固めて塊とすることができる。したがって、引出開始位置設定手段6を用いることにより、引出位置設定ステップが上述した傾斜ステップと同様の作用を奏することができる。   As shown in FIGS. 7 and 8, in the extraction position setting step, the extraction start position setting means 6 moves from the surface 21 of the CNT array 2 to the predetermined position X, and at the same time, the CNTs of the removal portion 2B are pressed and consolidated by the inclined surface 61. It can be made into a lump. Therefore, by using the drawing start position setting means 6, the drawing position setting step can perform the same operation as the tilt step described above.

傾斜面61によりCNTを押し固めて塊とする観点から、基板表面31の法線Vと引出開始位置設定手段6の除去部2B側の傾斜面61との角度θは、45°以上89°以下の範囲であることが好ましい。   From the viewpoint of pressing and solidifying the CNTs by the inclined surface 61 to form a lump, the angle θ between the normal V of the substrate surface 31 and the inclined surface 61 on the removal portion 2B side of the extraction start position setting means 6 is 45 ° or more and 89 ° or less. It is preferable that it is the range of these.

CNT供給源2A側のCNTは、引出ステップにおいてCNT構造体の原料となることから、引出位置設定ステップにおいて押し固められないようにすることが均一なCNT原料体を形成するために好ましい。この観点から、引出位置設定ステップでは、引出開始位置設定手段6のCNT供給源2A側の側面6Aには傾斜面61が設けられていない引出開始位置設定手段6を、側面6Aが上記法線Vと平行となるように、移動させることが好ましい。   Since the CNT on the CNT supply source 2A side becomes a raw material of the CNT structure in the extraction step, it is preferable that the CNT supply source 2A side be prevented from being compressed in the extraction position setting step in order to form a uniform CNT raw material. From this point of view, in the drawing position setting step, the drawing start position setting means 6 in which the inclined surface 61 is not provided on the side surface 6A on the CNT supply source 2A side of the drawing start position setting means 6 is shown in FIG. It is preferable to move it so that it is parallel to.

図7および図8に示したように、除去部2B側の側面6Bにのみ傾斜面61が形成された引出開始位置設定手段6を用いれば、引出位置設定ステップによって、CNT供給源2A側のCNTは押し固めることなく、除去部2Bを塊として取り除きやすくしながら引出開始位置23を設定することができる。したがって、引出ステップにより、引出開始位置23から均質なCNT構造体4を容易かつ安定的に引き出すことができる(図1(a)〜図1(c)参照)。   As shown in FIG. 7 and FIG. 8, if the drawing start position setting means 6 in which the inclined surface 61 is formed only on the side surface 6B on the removal unit 2B side is used, the CNT on the CNT supply source 2A side is obtained by the drawing position setting step. The extraction start position 23 can be set while easily removing the removal portion 2B as a lump without pressing. Therefore, the homogeneous CNT structure 4 can be easily and stably extracted from the extraction start position 23 by the extraction step (see FIGS. 1A to 1C).

引出開始位置設定手段として、引出開始位置設定手段1、5、6、7および後述されている8(図9〜図10参照)のいずれを用いるかは、原料として用いるCNTアレイや形成するCNT構造体の性質等に応じて、適宜選択すればよい。   Which of the drawing start position setting means 1, 5, 6, 7 and 8 described later (see FIGS. 9 to 10) is used as the drawing start position setting means depends on the CNT array used as a raw material and the CNT structure to be formed What is necessary is just to select suitably according to the property etc. of a body.

[糸状部材]
図9(a)〜図9(c)は、本発明の実施形態に係る製造方法において、糸状部材を有する引出開始位置設定手段を用いた場合を模式的に示している。図9(a)はCNTアレイの表面側から引出開始位置設定手段の挿入を開始する段階(所定位置Xへ移動させる前)の斜視図であり、図9(b)は引出開始位置設定手段を所定位置Xで停止させた段階の斜視図であり、図9(c)引出開始位置設定手段をCNTアレイのCNT供給源側から離れる方向に移動させてCNT構造体を引き出した段階(所定位置Xから移動させた後)の斜視図である。同図に示すCNT構造体の製造方法は、引出開始位置設定手段が板状部材ではなく、糸状部材81を有している引出開始位置設定手段8を用いる点において、図1(a)〜図1(c)に示した製造方法と異なっている。
[Threaded member]
FIG. 9A to FIG. 9C schematically show the case where the drawing start position setting means having a thread-like member is used in the manufacturing method according to the embodiment of the present invention. FIG. 9A is a perspective view of the stage of starting insertion of the drawing start position setting means from the surface side of the CNT array (before moving to the predetermined position X), and FIG. 9B shows the drawing start position setting means. FIG. 9C is a perspective view of a stage stopped at a predetermined position X, and FIG. 9C is a stage at which the CNT structure is pulled out by moving the extraction start position setting means away from the CNT supply source side of the CNT array (predetermined position X); FIG. The manufacturing method of the CNT structure shown in FIG. 1 is that the drawing start position setting means uses a drawing start position setting means 8 having a thread-like member 81 instead of a plate-like member. This is different from the manufacturing method shown in 1 (c).

図10は、本発明の実施形態に係る製造方法における糸状部材を備えている引出開始位置設定手段の断面形状の一例を示す、所定位置Xに移動した段階における図9(b)のB−B矢視断面図である。本実施形態において「糸状部材」とは、細長く連続した形状の部材をいい、図10に示すように、CNTアレイ2の高さHよりも、糸状部材の直径Lが小さいことをいう。換言すれば、所定位置Xに挿入された状態(図9(b)参照)において、CNTアレイ2の表面21の外側に位置する部分が有しないことをいう。   FIG. 10 shows an example of the cross-sectional shape of the drawing start position setting means provided with the thread-like member in the manufacturing method according to the embodiment of the present invention, and shows the BB in FIG. It is arrow sectional drawing. In the present embodiment, the “thread-like member” means a member having an elongated and continuous shape, and means that the diameter L of the thread-like member is smaller than the height H of the CNT array 2 as shown in FIG. In other words, it means that there is no portion located outside the surface 21 of the CNT array 2 in the state of being inserted at the predetermined position X (see FIG. 9B).

細長く連続した方向に対して垂直に切断した糸状部材81の断面形状としては、例えば、円形、楕円形、矩形、多角形などが挙げられる。また、糸状部材81には細長いリボン状のものも含まれる。これら例示した断面形状では、CNTアレイ2に挿入する際にどの側面から挿入しても同じ条件となるという点において、断面円形の糸状部材8が好ましい。   Examples of the cross-sectional shape of the thread-like member 81 cut perpendicular to the elongated and continuous direction include a circle, an ellipse, a rectangle, and a polygon. Further, the thread-like member 81 includes an elongated ribbon. In these exemplified cross-sectional shapes, the thread-like member 8 having a circular cross-section is preferable in that the same condition is satisfied regardless of which side is inserted into the CNT array 2.

引出開始位置設定手段101は、CNTアレイ2からCNT構造体4の引き出しを開始するための手段であり、上述した引出開始位置設定手段1、5〜8などを用いることができる(図1〜10参照)。   The extraction start position setting means 101 is a means for starting the extraction of the CNT structure 4 from the CNT array 2, and the above-described extraction start position setting means 1, 5 to 8, etc. can be used (FIGS. 1 to 10). reference).

制御手段102は、引出開始位置設定手段101をCNTアレイ2の表面側から基板3側に移動させて、所定位置Xで停止させて引出開始位置を設定し、引出開始位置設定手段101をCNTアレイ2から除去される除去部2B側に移動させて、CNTアレイ2からCNT構造体4を引き出す。例えば、引出開始位置設定手段101の位置をレールで規定して移動させる構成や、引出開始位置設定手段101の位置をロボットアームで移動させる構成や、除去部2Bをつまんで移動させる構成などが挙げられる。引出開始位置設定手段101の位置制御は、コンピュータなどを用いて行うことができる。   The control means 102 moves the drawing start position setting means 101 from the surface side of the CNT array 2 to the substrate 3 side, stops at the predetermined position X, sets the drawing start position, and sets the drawing start position setting means 101 to the CNT array. Then, the CNT structure 4 is pulled out from the CNT array 2. For example, a configuration in which the position of the drawing start position setting unit 101 is defined by a rail and moved, a configuration in which the position of the drawing start position setting unit 101 is moved by a robot arm, a configuration in which the removal unit 2B is pinched and moved, and the like. It is done. The position control of the drawing start position setting means 101 can be performed using a computer or the like.

板状部材を有する引出開始位置設定手段を用いる場合、制御手段は、所定位置において、板状部材を除去部側に傾斜可能な構成とすることが好ましい。板状部材の基板側の端部を同じ位置に維持したまま、反対側の端部を除去部側に移動させることにより、板状部材を除去部側に傾斜させることができる。この構成により、安定的に連続部2Cを引出開始位置23としてCNT構造を引き出すことができる(図6(a)、図6(b)参照)。   When using the drawing start position setting means having a plate-like member, it is preferable that the control means is configured to be able to incline the plate-like member toward the removal portion at a predetermined position. The plate-like member can be inclined to the removal portion side by moving the opposite end portion to the removal portion side while maintaining the substrate-side end portion of the plate-like member at the same position. With this configuration, the CNT structure can be pulled out stably with the continuous portion 2C as the drawing start position 23 (see FIGS. 6A and 6B).

糸状部材81を有する引出位置設定手段8を用いることにより、引出位置設定手段8とCNTアレイ2との接触を弱めることができるから、引出位置設定手段8に接するCNT供給源2Aが引出開始位置となる可能性を低下させて、連続部2Cを引出開始位置23とすることができる(図9(a)〜図9(c)、図10参照)。   By using the drawing position setting means 8 having the thread-like member 81, the contact between the drawing position setting means 8 and the CNT array 2 can be weakened, so that the CNT supply source 2A in contact with the drawing position setting means 8 is set to the drawing start position. The possibility of becoming lower can be reduced, and the continuous portion 2C can be set to the extraction start position 23 (see FIGS. 9A to 9C and FIG. 10).

引出開始位置設定手段とCNTアレイとの付着性は、CNT供給源側面よりも、除去部側面が高いことが好ましい。除去部側の側面のCNTアレイに対する付着性を高くすることにより、引出開始位置設定手段とCNTアレイ供給部との接触を弱めるとともに、引出開始位置設定手段とCNTアレイの除去部との接触を強めることができる。したがって、CNT構造体が引き出される際に、引出開始位置設定手段のCNTアレイ供給部側面が引出開始位置となる可能性を低下させて、CNTアレイの所定位置と基板表面との間の連続部を引出開始位置として均一なCNT構造体を引き出すことができる。   The adhesion between the drawing start position setting means and the CNT array is preferably higher on the side of the removal unit than on the side of the CNT supply source. By increasing the adhesion of the side surface on the removal unit side to the CNT array, the contact between the drawing start position setting unit and the CNT array supply unit is weakened, and the contact between the drawing start position setting unit and the removal unit of the CNT array is strengthened. be able to. Therefore, when the CNT structure is pulled out, the possibility that the side of the CNT array supply unit of the pulling start position setting means becomes the pulling start position is reduced, and a continuous portion between the predetermined position of the CNT array and the substrate surface is reduced. A uniform CNT structure can be drawn out as a drawing start position.

CNTアレイに対する「付着性」とは、CNTアレイの付着しやすさの程度をいう。例えば、引出開始位置設定手段の側面に接着剤や粘着剤を塗布することにより、CNTアレイを付着しやすくすることができる。接着剤や粘着剤の種類は特定されず、一般に用いられている天然系や合成系の接着剤や粘着剤を用いることができる   “Adhesiveness” to a CNT array refers to the degree of ease with which the CNT array adheres. For example, the CNT array can be easily attached by applying an adhesive or a pressure-sensitive adhesive to the side surface of the drawing start position setting means. The type of adhesive or pressure-sensitive adhesive is not specified, and commonly used natural and synthetic adhesives and pressure-sensitive adhesives can be used.

「CNT供給源側面」とは、引出開始位置設定手段のCNT供給源に接する側面をいう(図6、図10参照)。引出開始位置設定手段が、図6に示す板状部材1を有する場合、CNT供給源2Aと接する側面1AがCNT供給源側面である。図10に示す糸状部材8を有する場合、同図に示す糸状部材81の断面の中心線Yを基準としてCNT供給源2A側の側面81AがCNT供給源側面である。   The “CNT supply source side surface” refers to a side surface in contact with the CNT supply source of the drawing start position setting means (see FIGS. 6 and 10). When the drawing start position setting means has the plate-like member 1 shown in FIG. 6, the side surface 1A in contact with the CNT supply source 2A is the CNT supply source side surface. When the thread-like member 8 shown in FIG. 10 is provided, the side surface 81A on the CNT supply source 2A side is the CNT supply source side face with reference to the center line Y of the cross-section of the thread-like member 81 shown in FIG.

「除去部側面」とは、引出開始位置設定手段の除去部に接する側面をいう(図6、図10参照)。引出開始位置設定手段が、図6に示す板状部材1を有する場合、除去部2Bと接する側面1Bが除去部側面である。図10に示す糸状部材81を有する場合、同図に示す糸状部材81の断面の中心線Yを基準として、除去部2B側の側面81Bが除去部側面である。   The “removal part side surface” means a side surface in contact with the removal part of the drawing start position setting means (see FIGS. 6 and 10). When the drawing start position setting means has the plate-like member 1 shown in FIG. 6, the side surface 1B in contact with the removal portion 2B is the removal portion side surface. When the thread-like member 81 shown in FIG. 10 is provided, the side surface 81B on the removal portion 2B side is the removal portion side surface with reference to the center line Y of the cross-section of the thread-like member 81 shown in FIG.
