繊維状柱状物の長さLは、走査型電子顕微鏡(SEM)によって測定した。
ガラス(MATSUNAMI スライドガラス27mm×56mm)に、1cm2単位面積に切り出したナノインデンター用試料固定部材の先端(ナノインデンター用試料固定部材がカーボンナノチューブ集合体を含む場合は、カーボンナノチューブの先端)が接触するように載置し、5kgのローラーを一往復させてナノインデンター用試料固定部材の先端をガラスに圧着した。その後、30分間放置した。引張り試験機(Instro Tensil Tester)で引張速度50mm/minにて、室温(25℃)にてせん断試験を行い、得られたピークをせん断接着力とした。
カーボンナノチューブ集合体におけるカーボンナノチューブの層数および層数分布は、走査型電子顕微鏡(SEM)および/または透過電子顕微鏡(TEM)によって測定した。得られたカーボンナノチューブ集合体の中から少なくとも10本以上、好ましくは20本以上のカーボンナノチューブをSEMおよび/またはTEMにより観察し、各カーボンナノチューブの層数を調べ、層数分布を作成した。
ナノインデンター測定はバーコビッチ型三角錐型圧子を用いて行った。

荷重に対する校正データとの変位差の評価は下記の基準で行った。
○:荷重に対する校正データとの変位差が3nm以下。
×:荷重に対する校正データとの変位差が3nmより大きい。
