Description
本実施例では、本発明のBNNT材料(実施例1の試料)と、比較として、本発明のBNNT材料からBNフラーレン中空粒子を除いて作製したBNNT(比較例1の試料)を作製した。また、BNNT合成後にBNフラーレン中空粒子を添加してBNNTのバンドル化を抑制できるか否かを確認するため、BNNTとBNフラーレン中空粒子を別々に用意して混合して作製したBNNT材料(比較例2の試料)を作製した。以上の実施例1、比較例1、比較例2について、バンドル化の程度を評価した。
実施例1の試料を用いて、母材をアルミニウムとするBNNT複合材料を作製した。本発明のバンドル化が抑制され、高分散化されたBNNT材料を用いて、金属複合材料や樹脂複合材料などの各種のBNNT複合材料を作製することが可能である。本実施例では、BNNT複合材料として、BNNTとアルミニウムの複合材料(BNNT/Al複合材料)と、BNNTとフッ素樹脂の複合材料(BNNT/フッ素樹脂複合材料)を作製した。
次に、母材をフッ素含有樹脂とするBNNTとフッ素樹脂の複合材料を作製した。
BNNT/フッ素樹脂複合材料は、フッ素含有樹脂の有機溶液と、上記実施例1のBNNT材料の有機溶液を混合し、その後、有機溶媒を乾燥除去することにより作製した。BNNT材料の含有量は5質量%である。
