Abstract
Description
カーボンナノフィラー分散液は、親水基により表面修飾された修飾カーボンナノフィラーと、金属ナノフィラーと、水系溶媒と、を含有する。修飾カーボンナノフィラーは、図2又は図3に示す、循環式キャビテーションプラズマ処理装置によって、水系溶媒に分散されたグラファイト(カーボンナノフィラー)をプラズマ処理により表面を分散媒への親和性を有するように修飾させることによって得られる。
合成樹脂は、成形性の良さから、乗用車、家電など様々な工業製品に使用されている成型材料である。合成樹脂は、成形品の厚みを厚くすることによって高い強度(曲げ強さ、引張強さなど)を得ることができるが、重量の増大やコストの増大を招くため、成形品の厚みが薄くても高い強度が得られるものが求められる。実施形態の複合材料は、合成樹脂に上記のカーボンナノフィラー分散液が含有されることによって、成形品の厚みが薄くても、高強度の複合材料とすることができるものである。
カーボンナノフィラーとして使用するグラファイトは、表1に記載のグラファイトAを使用した。グラファイト分散液の配合は、表2に記載する。キャビテーションプラズマ処理装置には、表3に記載のキャビテーションプラズマ処理装置Aを使用した。
複合材料の混合には、東洋樹脂株式会社所有の二軸押出機(特注品)を使用し、表4に記載の条件で混合を行った。なお、合成樹脂には、ポリアミド6を使用し、カーボンナノフィラー分散液には、上記のカーボンナノフィラー分散液Aを使用した。
Claims (4)
- 親水基により表面修飾された修飾カーボンナノフィラーと、金属ナノフィラーと、水系溶媒と、を含有することを特徴とするカーボンナノフィラー分散液。
