同济大学声子学与热能科学中心与瑞士苏黎世联邦理工学院合作,在石墨烯层间导热性能研究方面取得了重要的成果,提出了一种显著提高石墨烯层间导热性能的新方法:用sp~2共价键(强相互作用)来代替石墨烯层间的范德华力(弱相互作用),构造无缝连接的石墨烯-碳纳米管混合结构。此外,研究人员还展示了通过流体将固体混 In collaboration with the Federal Institute of Technology Zurich, Switzerland, the Phonology and Thermal Science Center of Tongji University has made important achievements in the study of the thermal conductivity of graphene layers. A new method of significantly improving the thermal conductivity between layers of graphene is proposed: ~ 2 covalent bonds (strong interactions) to replace the van der Waals forces (weak interactions) between the graphene layers to construct a seamlessly connected graphene-carbon nanotube mixed structure. In addition, the researchers also demonstrated mixing of solids by fluid
