Abstract
Description
(a)配向されていないナノチューブを含んだカーボンナノチューブの不織シートを準備するステップ、
(b)このカーボンナノチューブの不織シートをカップリング剤と接触させて、隣接するカーボンナノチューブ間の機械的結合を得るステップ、
(c)機械的に結合したカーボンナノチューブを含んだこのカーボンナノチューブの不織シートを延伸して、
(i)カーボンナノチューブ間のストレスを与え、かつ
(ii)不織シートが延伸される方向に個々のナノチューブの配向を与えるステップ
を含む不織シート中のカーボンナノチューブを配向させる方法に向けられる。
パートI
カーボンナノチューブの不織シートをまず過剰のクロロスルホン酸で均一に濡らす。その後、その濡れた不織シートを破断するまで延伸する。最初の長さおよび最終の長さを記録し、下記の式を使用して破壊歪みを計算する。
破壊歪み=(最終の長さ−最初の長さ)/最初の長さ×100
カーボンナノチューブの別の不織シートを、まず潜在性カップリング剤と組み合わせた過剰のクロロスルホン酸で濡らしかつ接触させる。このクロロスルホン酸および潜在性カップリング剤は、重量を基準にして99対1の比で存在する。この濡らし、接触させた不織シートを破断するまで延伸する。
破壊歪み=(最終の長さ−最初の長さ)/最初の長さ×100
(パートIおよびパートIIの試験手順では歪み速度および温度を含めたすべての変数は同一である。パートIとパートIIの違いは、カップリング剤が存在しないか存在するかである。)
クロロスルホン酸と潜在性カップリング剤が、重量を基準にして99.9対0.1の比で存在すること除いて、パートIIAと同じ手順に従う。
クロロスルホン酸と潜在性カップリング剤が、重量を基準にして90対10の比で存在すること除いて、パートIIAと同じ手順に従う。
代わりの試験法は、クロロスルホン酸の代わりに硫酸を使用することを除いて試験法Aと同一である。硫酸および潜在性カップリング剤は、99対1(試験法BパートIIA)、99.9対0.1(試験法BパートIIB)、および90対10(試験法BパートIIC)の比で存在する。
本発明の好ましい実施形態ではカップリング剤と共に希釈液が使用されることになる。希釈液は、隣接するカーボンナノチューブ間の結合の程度を制御することを可能にし、カーボンナノチューブが相互間で位置を変えることを可能にし、かつカーボンナノチューブの配向を容易にする。したがって希薄液を使用することが高度に好ましい。希釈液なしでの不織シートの延伸操作においてはより一層の注意が必要である。
試験法Aおよび試験法Bを引き受ける適切な装置を図示する。中ぐり棒支え(outer support)1は、2本の平行なネジ棒2を含有する。静止クランプ3および移動クランプ4が、不織カーボンナノチューブのシートである試験片を保持する。軸受け5(モーターまたは手廻しクランクに取り付けられた)がネジ棒の回転を可能にし、それによって移動クランプが試験片にストレスをかける。過剰なストレスが破断を引き起こす。代わりの装置は、Lashmoreの米国特許出願公開第2009/0075545号明細書に開示されている。
カーボンナノチューブの配向不織シートは、広角X線回折によって得られる(FWHM)値を有することになる。この(FWHM)値は、20°を超えず、好ましくは10°以下、またさらに一層好ましくは5°以下であるはずである。
(FWHM)値は、不織シートを光線に対して直角に装着した状態でCu Kα放射線(波長=0.1542nm)を使用する広角X線回折によって求められる。赤道反射の方位角強度スキャンの半値全幅(FWHM)の値は、2θ=25°の領域に現れる。
