石墨烯具有高导电性、高导热性以及稳定性,因而被认为是一种良好的驱动材料。而智能材料是指能感知外部刺激且本身可执行的新型功能材料。聚合物/石墨烯智能复合材料兼具石墨烯材料和智能材料的特性,因而被应用到驱动器的设计中。概述了聚合物/石墨烯智能复合材料驱动器的最新进展,并且讨论了在多种驱动条件或刺激下石墨烯所发挥的作用,介绍了不同刺激下聚合物/石墨烯复合材料的制备方法,最后对聚合物/石墨烯智能复合材料及器件作了总结并对其前景作了展望。
Graphene has recently been revealed to be an outstanding actuating material due to its high electron mobility,high thermal conductivity and environmental stability.The intelligent materials are new functional materials which are sensitive to external stimulus.Polymer/graphene composite combines the properties of graphehe and intelligent material,which is applied in the design of actuator.Some of the recent advances in polymer/graphene intelligent composite actuators were summarized,and discussed the different roles that graphene played in various actuation circumstances or stimulus.Preparation methods and prospects of composite were also discussed.
