石墨烯（ graphene ）是由单层碳原子紧密堆积成二维蜂窝状晶格结构的一种碳质新材料，是构建其它维度碳质材料（如零维富勒烯、一维碳纳米管、三维石墨）的基本单元。虽然人们已在理论上研究了石墨烯六十多年，但石墨烯一直被认为不可能以自由态存在，直到 2004 年被 Novoselov 等发现 。石墨烯具有优异的电学、热学和力学性能，可望在高性能纳电子器件、复合材料、场发射材料、气体传感器及能量存储等领域获得广泛应用 。由于其独特的二维结构和优异的晶体学结构，石墨烯蕴含了丰富而新奇的物理现象，具有重要的理论研究价值。 我们课题组通过对石墨烯的表面改性制备了在极性基液中（如水、乙醇、乙二醇等）稳定的石墨烯胶体。通过对石墨烯的表面修饰，制备了在非极性基液中分散的胶体，可以在液体石蜡、 DMF 等非极性溶液中很好的分散。 鉴于大家对于可溶性的石墨烯非常感兴趣，特整理了以下文献，供大家参考： 1.Bourlinos, A.B., et al., Aqueous-phase exfoliation of graphite in the presence of polyvinylpyrrolidone for the production of water-soluble graphenes.
