Description
本出願は2011年12月12日に出願された米国特許仮出願番号第61/569,435号の優先権を主張するものであり、参照によりその全体が本明細書に組み込まれる。
ここで用いる「重量部」とはゴム100重量部に対する配合物の重量部のことである。
補強材の例としては無機充填材が挙げられる。無機充填材としては、例えば、シリカ、ケイ酸塩、クレイ、ナノクレイなどのケイ素含有化合物が挙げられる。例として、ガラス、ケイ酸アルミニウム、ケイ灰石、カオリン、モンモリロナイト(ナノクレイを含む)、ハロイサイト(ナノクレイを含む)、亜塩素酸塩、焼成クレイなどが含まれる。
補強材はグラフェンシートの他には炭素充填材でもよく、これにはカーボンブラック、カーボンナノチューブなどが含まれる。
補強材は繊維状でもよく、これには短繊維(例えば、ガラス、炭素、ポリアラミド、超高分子量ポリエチレン)、ナノチューブ類(カーボンナノチューブ類(例えば、単層および2層ナノチューブ)、ケイ酸塩を含む)などが含まれる。これらは繊維をマット状又は織物状にしたものでもよい。
いくつかの態様では、特に低表面積の充填材(例えば、無機充填材、ケイ素含有剤、カーボンブラック、グラファイト)などが使用される場合、前記組成物は、約1重量部〜約100重量部の充填材、又は約10〜約100重量部の充填材、又は約20〜約100重量部の充填材、又は約30〜約100重量部の充填材、又は約40〜約100の重量部の充填材、又は約50〜約100重量部の充填材、又は約60〜約100重量部の充填材、又は約10〜約80重量部の充填材、又は約20〜約80重量部の充填材、又は約30〜約80重量部の充填材、又は約40〜約80重量部の充填材、又は約50〜約80重量部、又は約60〜約90重量部の充填材を含んでもよい。
加熱はバッチプロセス又は連続プロセスで行うことができ、また不活性及び還元性雰囲気(例えば、窒素、アルゴン、及び/又は水素雰囲気)を含む種々の雰囲気下で行うことができる。加熱時間は、用いる温度や最終的な熱剥離グラファイト酸化物の所望の特性に応じて、数秒から数時間以上の範囲にわたってもよい。加熱は、任意の適切な容器、例えば、溶融シリカ、鉱物、金属、炭素(グラファイト等)、セラミックなどの容器内で行うことができる。加熱は閃光電球を用いてもよい。加熱中、グラファイト酸化物は、1基のバッチ反応容器中の本質的に一定の場所に置かれていてもよく、又は連続式やバッチ式の反応時に1基以上の容器を介して搬送されてもよい。加熱は、炉や赤外線ヒーターの使用を含む任意の好適な手段を用いて行ってよい。
染色は次のように行われる。既知量のグラフェンシートをフラスコに加える。次いで、グラフェンシート1グラム当たり少なくとも1.5gのMBをフラスコに添加する。エタノールをフラスコに添加し、この混合物を約15分間超音波処理する。その後、エタノールを蒸発させ、既知量の水をフラスコに添加して遊離MBを再溶解する。未溶解材料は、好ましくは試料を遠心分離することで沈降させる。溶液中のMBの濃度は、UV−可視分光光度計を用いて基準濃度時の吸光度に対し、λmax=298nmにおける吸光度を測定することにより判定する。
前記組成物は、シール、ケーブル、プロファイル、ホース、工業用ゴム製品、ベルト、コンベヤーベルト、動力伝達ベルト、ローラー、床材、ゴルフボール、窓、振動制御用途(地震防護装置(ゴムベアリング等)、床、壁、窓、ヘリコプターの振動ダンパー等)に使用してもよい。
