PROBLEM TO BE SOLVED: To provide rubber compositions having improved mechanical properties and decreased hysteresis.SOLUTION: A composition comprises graphene sheets, at least one reinforcing agent, and at least one rubber. Preferably, the graphene sheets have a surface area of at least 300 m/g and a carbon-to-oxygen molar ratio of at least 10:1, and are contained in an amount of about 0.1 to about 20 pts.wt. in the total composition. The composition may further comprise carbon black. A tire formed from such the composition is also preferable.SELECTED DRAWING: None

    【課題】ヒステリシスを減少させ、機械的特性を向上したゴム組成物を得る。【解決手段】グラフェンシートと、少なくとも1種の補強材と、少なくとも1種のゴムと、を含む組成物。より好ましくはグラフェンシートは、少なくとも300m2/gの表面積を有し、10:1以上の炭素対酸素比を有し、全組成物中に約0.1〜約20重量部を含有する。この組成物は、更にカーボンブラックを含んでもよい。これらの組成物から形成されるタイヤも好ましい。【選択図】なし
