Description
グラフェン−金属混合物を製造するにあたり、グラフェン溶液内のグラフェン含量に対する金属物質の含量は、得ようとするグラフェン層によって制御されることができる。即ち、素地鋼板上にコーティングされたグラフェン層を純粋のグラフェン層に得ようとする場合はグラフェンと金属物質を約1:1程度に混合することが好ましく、グラフェン−金属複合層の形態にグラフェン層を得ようとする場合はグラフェンと金属物質を約1:2または1:2以上程度に混合することが好ましい。このとき、グラフェンに比べて金属物質の含量が高い場合、グラフェンの電荷を帯びる性質が高くなって素地鋼板上に蒸着される速度を速くすることができる。
まず、グラフェン溶液としては、化学的剥離法を用いて黒鉛からグラフェンを分離し、酸化還元法によって製造されたRGO溶液(Angstron materials社)を用意し、グラフェンパウダー/プレートレットとしては、グラフェンナノプレートレット(XG−SCIENCE社)を購買して用意した。
