Description
1つまたは複数のガス状反応物質の流れを反応器に通す工程と、
反応器の反応領域内で1つまたは複数のガス状反応物質を反応させて、生成物粒子を形成する工程と、
生成物粒子を凝集物へと凝集させる工程と、
凝集物に力を加えて、それを反応領域外に連続的に移動させる工程と
を含む凝集物の製造方法を提供する。
1.ポリマー充填剤
この使用は、繊維の機械的、電気的および熱的特性を利用する。繊維はプレプレグに織られ得る。スピンコーティングを用いて、複雑な形状を有する物体を形成し得る。
2.高級衣類に用いられる伝導性生地
3.電極
4.フィルターに関するガス吸収
5.ガス貯蔵
反応器の反応領域内で炭素源を反応させてカーボンナノチューブを生成する工程と、
カーボンナノチューブに力を加えることによりカーボンナノチューブを凝集物へと凝集させる工程と
を含むカーボンナノチューブ凝集物の製造方法を提供する。
本発明の好ましい一実施形態では、該方法は、図1に示した装置で実行する。該装置は、垂直配列円筒形石英反応器12を取り囲む垂直配列円筒形炉10より成る。代替的反応器は、円錐形であり得る。反応器12は、その上端に注入口14を、その下端に放出口16を有する。注入口14近くの反応器12内に配置されるのは、金属ワイヤの環の形態のナノチューブキャッチャ18である。代替的実施形態では、ナノチューブキャッチャ18は、ガラスワイヤまたは磁性材料の環であり得る。放出口16近くの反応器12内に配置されるのは、水平に延びるねじ20、適切には長さ300mmのステンレススチールねじである。代替的実施形態では、ねじは垂直に、または他の方向に延び得る。ねじ20はモーター22に連結され、内部ねじ込み棒21を保有する。
上記と同様の方法を、図1の装置の変形型を用いて実行した。
実施例1の反応条件ならびに図1の装置の変形型を用いて、多層カーボンナノチューブを生成した。
図1の装置のさらなる変形型を用いて、実施例2を繰り返した。この変形を図8に示す。ねじ20および棒21を、反応軸に対して約25°の角度のスピンドル20’に取り換えて、60rpmでその軸の周囲を回転させた。その他の数字で示した部分は、図1/実施例1と同じである。このスピンドルは反応器の熱領域(管の横断面積の約12%を覆う)に貫入して、エーロゲルを捕獲した後、それは冷却領域に到達し、そこでそれは壁に突き刺さり得る。
スピンドルを用いずに、実施例2を反復した。エーロゲルはガス流に伴って炉を下降し、これは、温度低下のために炉の下方部分で減速した(熱領域では6.5mm/秒、500℃点では3.5mm/秒)。エーロゲルが炉の冷却端に到達すると、それは炉壁に張り付いて、炉全体に極薄い膜を形成し、これは時間とともに厚くなった。
