A.グラファイト化金属触媒の前駆体水溶液の製造
グラファイト化触媒としてCo−V金属触媒を準備した。
Vの前駆体物質としてNH4VO3を20mlの水に溶解させたフラスコAにクエン酸を投入した。Co:Vのモル比が10:1になるように、Coの前駆体物質としてCo(NO3)2・6H2Oを投入した。製造された金属水溶液は、沈殿が見えない綺麗な溶液状態で観察された。
アルミニウム系支持体として水酸化アルミニウム(Al(OH)3)を250〜500℃で4時間焼成して得られた支持体20gをフラスコBに準備した。XRD分析によれば、焼成後の支持体は、AlO(OH)を40重量%以上含むものと表された。
ATH400 20gをモル基準100に換算すれば、Coが30モル、Vが3モルになるように、フラスコBに前記フラスコAの溶液40gを添加した。グラファイト化金属触媒の前駆体を十分にATH400に担持させた後、60℃の恒温槽で5分間撹拌して熟成させた。それを前記温度に維持しながら、80rpmで回転させ、真空乾燥下で60分間乾燥させた。乾燥した触媒を675℃で4時間第2焼成させ、担持触媒を製造した。

Cu Kα radiation(波長:1.54Å)

前記で製造されたCNT合成用担持触媒をそれぞれ用いて、実験室規模の流動層反応装置でCNT合成を試した。具体的には、前記Cで製造されたCNT合成用触媒を、直径58mmの内径と長さ1200mmの石英管反応器で窒素雰囲気で675℃まで昇温した後に維持させ、窒素、水素及びエチレンガスの体積混合比を5.5:1:1で分当たり総4000ml流しながら2時間合成して、所定量のCNT集合体を合成した。
実施例による触媒で製造されたCNT集合体の含量が3重量%になるようにポリカーボネート(MI22)と混合した後、二軸スクリュー押出機を用いて240〜280℃に溶融押出してペレット形態のコンパウンドを製造した。前記コンパウンドを使用して伝導度測定用試片を製作した後、伝導度測定器(SRM−110、PINION社製)を使用して伝導度を測定した。触媒の結晶サイズによる高分子複合材の表面抵抗の関係を図4に示した。
