【摘要】：日益流行的柔性电子器件要求在反复变形状态下,材料仍能保持优异的力学和电学性能.而石墨烯作为一种二维(two dimensional,2D)碳纳米片,具有独特的力学和电学性能,成为构筑此类柔性电子器件的首选基元材料.然而,如何将石墨烯纳米片组装成高性能的石墨烯纳米复合材料,仍然存在巨大挑战.天然鲍鱼壳因其内部有序规整的层状结构和丰富的界面相互作用,而具有综合优异的力学性能.这种独特的界面结构设计,为2D纳米片仿生组装提供了新的思想源泉.本文按照"有所发现,有所发明,有所创造"的学术研究思路,总结了最近几年国内外课题组关于仿生石墨烯纳米复合材料(bioinspired graphene-based nanocomposites,BGBNs)的研究进展;分析了石墨烯层间不同的界面相互作用;详细讨论了基于协同效应,仿生构筑强韧一体化石墨烯纳米复合材料的策略;重点阐述了BGBNs的拉伸强度、韧性以及电导率等基本物理性能.最后,本文也简单概括了BGBNs在柔性电子器件领域的应用和潜在的挑战,并展望了BGBNs未来的发展方向.
[Abstract]:The increasingly popular flexible electronic devices require that the materials can maintain excellent mechanical and electrical properties in the state of repeated deformation. Graphene, as a two-dimensional (two dimensional,2D) carbon nanochip, has unique mechanical and electrical properties and has become the preferred basic material for the construction of this kind of flexible electronic devices. However, how to assemble graphene nanocomposites into high performance graphene nanocomposites remains a great challenge. Natural abalone shell has excellent mechanical properties because of its ordered layered structure and rich interfacial interaction. This unique interface structure provides a new source of thought for bionic assembly of 2D nanochips. In this paper, according to the academic research ideas of "some discoveries, inventions and innovations", the research progress of bionic graphene nanocomposites (bioinspired graphene-based nanocomposites,BGBNs) at home and abroad in recent years is summarized. The different interfacial interactions between graphene layers are analyzed, the strategy of bionic construction of graphene nanocomposites based on synergism is discussed in detail, and the tensile strength of BGBNs is discussed. Toughness and electrical conductivity and other basic physical properties. Finally, the application and potential challenges of BGBNs in the field of flexible electronic devices are briefly summarized, and the future development of BGBNs is prospected.
