Description
本願は、2013年12月10日出願のMiao Yuによる米国仮特許出願第61/914,011号、発明の名称「水処理用の超薄型グラフェンベース膜ならびにそれらの形成法及び使用」に基づく優先権を主張し、これを引用によって本明細書に援用する。
本開示は、一般的に、調節可能な細孔径を有する超薄型のグラフェンベースの膜を形成する方法に向けられる。得られる超薄型グラフェンベース膜は高効率の水処理に特に適している。
全般的に、膜を形成するための方法が提供される。一態様において、当該方法は、GOナノ粒子を溶媒中に分散させ;GOナノ粒子を支持体上に付着させてGO膜を形成させ;そしてGO膜を還元してrGO膜を形成させることを含む。また、そのような方法から形成されたrGO膜を複数の積重ねrGO層とともに提供する。水/油エマルションから、例えば水をrGO膜に通すことによって、水を分離するための方法も提供される。
当業者に対する本発明の、その最良の形態を含む完全かつ実施可能な開示は、本明細書の残りの部分において、添付図面への参照とともに、さらに詳細に示される。
本明細書において、接頭辞“ナノ”は、ナノメートルスケール(例えば、約1nm〜約100nm)のことを言う。例えば、ナノメートルスケール(例えば、約1nm〜約100nm)の平均直径を有する粒子は“ナノ粒子”と呼ばれる。
次に、本発明の態様について言及し、その一つ又は複数の実施例を以下に示す。各実施例は、本発明を説明するために提供されているのであって、本発明の制限として提供されているのではない。実際、当業者には、本発明において、本発明の範囲又は精神から逸脱することなく、様々な修正及び変形が可能であることは明白であろう。例えば、一つの態様として説明又は記載されている特徴を別の態様で使用して、なお更なる態様を得ることも可能である。従って、本発明は、そのような修正及び変形も、添付のクレーム及びそれらの均等物の範囲内に含まれるとしてカバーするものとする。当業者であれば、本解説は、例示的態様の説明に過ぎず、本発明のより広い側面を制限することを意図していないことは分かるであろう。そのより広い側面は、例示的構成において具体化されている。
UV誘導酸化とスチームエッチングを用いてグラフェンナノフレークを制御的にエッチングし、構造欠陥サイズを制御的に増大させて、標的分離にふさわしい所望の細孔径を作り出すことができる。約0.4nm未満(グラフェン上の構造欠陥)から約10nmを超える(例えば、約0.3nm〜約20nm、例えば約0.4nm〜約10nm)調節可能な細孔径と、ごく薄い厚さ(例えば、約5nm未満(例えば約2nm〜約5nm))は、小気体分子の分離(H2分離、CO2捕捉など)、脱塩及び浄水用のナノろ過から透析などの医療用途まで、広範な分離用途を超薄型グラフェンベース膜が有することを可能にする。
本発明の一つの特別な態様に従って、酸化グラフェン膜を利用して、水/油エマルション/混合物から水を分離する。酸化グラフェン膜の使用により、水/油エマルションからの水の分離は、従来の膜よりも1桁高い透水量で達成できる。
ii)極めて薄い膜厚とGOフレーク間の2次元間隙を通る低摩擦水流のために高透水性であること;
iii)水の透過中のナノメートルサイズの間隙及び親水性の膜入口(membrane entrance) のため、膜ファウリング、特に内部ファウリングに対して優れた抵抗性があること;
iv)GO膜の製造プロセスの優れた拡張可能性;及び
v)膜厚が極めて薄いため、膜材料が低コストであること。
一つの特別な態様において、還元型GO(“rGO”)は、水に対しては不透性で、有機化合物に対して高透過性であることが示されている。従って、水からの有機物抽出は、還元型GO膜を用いて達成できる。
単層GO(SLGO)ナノフレークを利用して超薄型(1.8〜18nm)GO膜を製造した。ろ過により、超薄型GO膜を陽極酸化アルミニウム(AAO)多孔性支持体(20nm細孔)上に製造し、純ガスの透過とH2混合物の分離を測定した。H2は、GOフレーク上の小さな構造欠陥を選択的に透過することが見出され、H2/CO2及びH2/N2混合物の選択性は、それぞれ3400及び900に達した。このことは、簡便なろ過によって製造された超薄型GO膜が高品質を有し、有効膜細孔径は、CO2(動的直径(kinetic diameter):0.33nm)及びN2(0.364nm)分子よりも小さいことを示している。従って、GOフレーク上の構造欠陥は、水和一価イオン(〜0.6nm)を除去すると予想される。
膜技術を用いる混合物分離は、産業プロセスにおけるエネルギーコストを大きく削減できる。この技術の中心は、高流量を有する高選択膜である。グラファイトの単層であるグラフェンは、極めて薄く、ゆえに高透過量を提供できるため、理想的な膜材料と見なされている。しかしながら、現在のところ、混合物を高度に選択的に分離できる超薄型(<5nm)グラフェンベース膜を製造するのに利用できる技術がない。本発明では、低コストで超薄型(2nmに至る)及び無欠陥の、調節可能な細孔径(0.3〜20nm)を有するグラフェンベース膜を製造するための拡張可能なろ過技術を開発した。この完全に新タイプの膜は、高選択性と高流量をともに提供できるので、膜技術を用いる分離に大変革をもたらす大きな可能性を秘めている。
